Why two NDCs? The FDA registers this code as 17772-102-01 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 17772-0102-01. Same drug, same package — only the format differs.

🩺 Clinical

Label name TROKENDI XR 50 MG CAPSULE Ingredient Topiramate
📖 What it is MedlinePlus · NLM

Topiramate is used to treat certain types of seizures. Topiramate is also used to prevent migraine headaches but not to relieve the pain of migraine headaches when they occur. Topiramate is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

💡 Tap an ingredient (hover on desktop) to see what it is and why it’s used.

  • UNII 656HXR6YXN

20 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

FDA-approved generic versions are listed, and recent pricing/market data suggests they may be available — see Therapeutic equivalents.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Apr 2028. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Aug 16, 2013 AB1 TE-rated RLD RS ⏳ ~1.5 yr to latest listed protection

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of TROKENDI XR 50 MG CAPSULE?
Yes — an FDA-approved generic equivalent is listed in the FDA Orange Book for TROKENDI XR 50 MG CAPSULE. See the alternatives section for substitutable, lower-cost products.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

Medicare Part D (outpatient prescription) spending for Trokendi XR — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Trokendi XR. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION TROKENDI XR initial dose, titration, and recommended maintenance dose varies by indication and age group. See Full Prescribing Information for recommended dosage, and dosing considerations in patients with renal impairment, geriatric patients, and patients undergoing hemodialysis ( 2.1 , 2.2 , 2.3 , 2.4 , 2.5 , 2.6 ) Swallow capsule whole and intact. Do not sprinkle on food, chew, or crush ( 2.7 )

2.1Dosing in Monotherapy Epilepsy Adults and Pediatric Patients 10 Years of Age and Older with Partial Onset or Primary Generalized Tonic-Clonic Seizures The recommended dose for TROKENDI XR monotherapy in adults and in pediatric patients 10 years of age and older is 400 mg orally once daily. Titrate TROKENDI XR according to the following schedule: Week 1: 50 mg once daily Week 2: 100 mg once daily Week 3: 150 mg once daily Week 4: 200 mg once daily Week 5: 300 mg once daily Week 6: 400 mg once daily Pediatric Patients Ages 6 to 9 Years of Age Dosing in patients 6 to 9 years of age is based on weight.

During the titration period, the initial dose of TROKENDI XR is 25 mg/day nightly for the first week. Based upon tolerability, the dosage can be increased to 50 mg/day in the second week. Dosage can be increased by 25 mg to 50 mg/day each subsequent week as tolerated.

Titration to the minimum maintenance dose should be attempted over 5-7 weeks of the total titration period. Based upon tolerability and clinical response, additional titration to a higher dose (up to the maximum maintenance dose) can be attempted at 25 mg to 50 mg/day weekly increments. The total daily dose should not exceed the maximum maintenance dose for each range of body weight (see Table 1 ).

Table 1: Monotherapy Target Total Daily Maintenance Dosing for Patients 6 to 9 Years of Age Weight (kg) Total Daily Dose (mg/day) Minimum Maintenance Dose Total Daily Dose (mg/day) Maximum Maintenance Dose Up to 11 150 250 12 - 22 200 300 23 - 31 200 350 32 - 38 250 350 Greater than 38 250 400

2.2Dosing in Adjunctive Therapy Epilepsy Adults (17 Years of Age and Older) The recommended total daily dose of TROKENDI XR as adjunctive therapy in adults with partial-onset seizures or Lennox-Gastaut Syndrome is 200 mg to 400 mg orally once daily and with primary generalized tonic-clonic seizures is 400 mg orally once daily. Initiate therapy at 25 mg to 50 mg once daily followed by titration to an effective dose in increments of 25 mg to 50 mg every week. Titrating in increments of 25 mg/day every week may delay the time to reach an effective dose.

Doses above 400 mg/day have not been shown to improve responses in adults with partial-onset seizures. Pediatric Patients 6 to 16 Years of Age The recommended total daily dose of TROKENDI XR as adjunctive therapy for patients 6 to 16 years of age with partial-onset seizures, primary generalized tonic-clonic seizures, or seizures associated with Lennox-Gastaut syndrome is approximately 5 mg/kg to 9 mg/kg orally once daily. Begin titration at 25 mg once daily (or less, based on a range of 1 mg/kg/day to 3 mg/kg/day) given nightly for the first week.

Subsequently, increase the dosage at 1- or 2-week intervals by increments of 1 mg/kg/day to 3 mg/kg/day to achieve optimal clinical response. Dose titration should be guided by clinical outcome. The total daily dose should not exceed 400 mg/day.

2.3Dosing for the Preventive Treatment of Migraine The recommended total daily dose of TROKENDI XR as treatment for the preventive treatment of migraine in patients 12 years of age and older is 100 mg once daily. Titrate TROKENDI XR for the preventive treatment of migraine according to the following schedule: Week 1: 25 mg once daily Week 2: 50 mg once daily Week 3: 75 mg once daily Week 4: 100 mg once daily Dose and titration rate should be guided by clinical outcome. If required, longer intervals between dose adjustments can be used.

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Acute myopia and secondary angle closure glaucoma: can lead to permanent visual loss; discontinue TROKENDI XR as soon as possible ( 5.1 ) Visual field defects: consider discontinuation of TROKENDI XR ( 5.2 ) Oligohydrosis and hyperthermia: monitor decreased sweating and increased body temperature, especially in pediatric patients ( 5.3 ) Metabolic acidosis: baseline and periodic measurement of serum bicarbonate is recommended; consider dose reduction or discontinuation of TROKENDI XR if clinically appropriate ( 5.4 ) Suicidal behavior and ideation: antiepileptic drugs increase the risk of suicidal behavior or ideation ( 5.6 ) Cognitive/neuropsychiatric adverse reactions: use caution when operating machinery including cars; depression and mood problems may occur ( 5.7 ) Fetal toxicity: use during pregnancy can cause major congenital malformations, including but not limited to cleft lip and/or palate, and being small for gestational age ( 5.8 ) Withdrawal of AEDs: withdraw TROKENDI XR gradually ( 5.9 ) Decrease in Bone Mineral Density: has been shown to decrease bone mineral density and bone mineral content in pediatric patients ( 5.10 ) Negative effects on growth (height and weight): may slow height increase and weight gain; carefully monitor children receiving prolonged therapy ( 5.11 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity, serious skin reactions, anaphylaxis, and angioedema: Discontinue TROKENDI XR if an alternative etiology cannot be established ( 5.12 , 5.13 , 5.14 ) Hyperammonemia/encephalopathy: measure ammonia if encephalopathic symptoms occur ( 5.15 ) Kidney stones: avoid use with other carbonic anhydrase inhibitors, other drugs causing metabolic acidosis, or in patients on a ketogenic diet ( 5.16 ) Hypothermia has been reported with and without hyperammonemia during topiramate treatment with concomitant valproic acid use ( 5.17 )

5.1Acute Myopia and Secondary Angle Closure Glaucoma Syndrome A syndrome consisting of acute myopia associated with secondary angle closure glaucoma has been reported in patients receiving topiramate. Symptoms include acute onset of decreased visual acuity and/or ocular pain. Ophthalmologic findings can include some or all of the following: myopia, mydriasis, anterior chamber shallowing, ocular hyperemia (redness), choroidal detachments, retinal pigment epithelial detachments, macular striae, and increased intraocular pressure.

This syndrome may be associated with supraciliary effusion resulting in anterior displacement of the lens and iris, with secondary angle closure glaucoma. Symptoms typically occur within 1 month of initiating topiramate therapy. In contrast to primary narrow angle glaucoma, which is rare under 40 years of age, secondary angle closure glaucoma associated with topiramate has been reported in pediatric patients as well as adults.

The primary treatment to reverse symptoms is discontinuation of TROKENDI XR as rapidly as possible, according to the judgment of the treating physician. Other measures, in conjunction with discontinuation of TROKENDI XR, may be helpful. Elevated intraocular pressure of any etiology, if left untreated, can lead to serious sequelae including permanent vision loss.

5.2Visual Field Defects Visual field defects (independent of elevated intraocular pressure) have been reported in clinical trials and in postmarketing experience in patients receiving topiramate. In clinical trials, most of these events were reversible after topiramate discontinuation. If visual problems occur at any time during treatment with TROKENDI XR, consideration should be given to discontinuing the drug.

5.3Oligohydrosis and Hyperthermia Oligohydrosis (decreased sweating), resulting in hospitalization in some cases, has been reported in association with topiramate use. Decreased sweating and an elevation in body temperature above normal characterized these cases. Some of the cases were reported after…

6 ADVERSE REACTIONS The following serious adverse reactions are discussed in more detail in other sections of the labeling: Acute Myopia and Secondary Angle Closure Glaucoma [see Warnings and Precautions (5.1) ] Visual Field Defects [see Warnings and Precautions 5.2 ] Oligohydrosis and Hyperthermia [see Warnings and Precautions (5.3) ] Metabolic Acidosis [see Warnings and Precautions (5.4) ] Interaction With Alcohol [see Warnings and Precautions (5.5) ] Suicidal Behavior and Ideation [see Warnings and Precautions (5.6) ] Cognitive/Neuropsychiatric Adverse Reactions [see Warnings and Precautions (5.7) ] Fetal Toxicity [see Warnings and Precautions (5.8) ] Withdrawal of Antiepileptic Drugs [see Warnings and Precautions (5.9) ] Decrease of Bone Mineral Density [see Warnings and Precautions (5.10) ] Negative Effects on Growth (Height and Weight) [see Warnings and Precautions (5.11) ] Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity Reactions [see Warnings and Precautions (5.12) ] Serious Skin Reactions [see Warnings and Precautions (5.13) ] Anaphylaxis and Angioedema [see Warnings and Precautions (5.14) ] Hyperammonemia and Encephalopathy (Without and With Concomitant Valproic Acid Use) [see Warnings and Precautions (5.15) ] Kidney Stones [see Warnings and Precautions (5.16) ] Hypothermia With Concomitant Valproic Acid Use [see Warnings and Precautions (5.17) ] The data described in the following sections were obtained using immediate-release topiramate tablets.

TROKENDI XR has not been studied in a randomized, placebo-controlled Phase III clinical study; however, it is expected that TROKENDI XR would produce a similar adverse reaction profile as immediate-release topiramate. Epilepsy: Most common (≥10% more frequent than placebo or low-dose topiramate) adverse reactions in adult and pediatric patients were paresthesia, anorexia, weight loss, speech disorders/related speech problems, fatigue, dizziness, somnolence, nervousness, psychomotor slowing, abnormal vision, and fever ( 6.1 ).

Migraine: Most common (≥5% more frequent than placebo) adverse reactions in adult and pediatric patients were: paresthesia, anorexia, weight loss, difficulty with memory, taste perversion, diarrhea, hypoesthesia, nausea, abdominal pain, and upper respiratory tract infection ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Supernus Pharmaceuticals, Inc. at 1-866-398-0833 or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Monotherapy Epilepsy Adults 16 Years of Age and Older The most common adverse reactions in the controlled trial (Study 1) that occurred in adults in the 400 mg/day topiramate group and at an incidence higher (≥10%) than in the 50 mg per day group were: paresthesia, weight loss, and anorexia (see Table 3 ).

Approximately 21% of the 159 adult patients in the 400 mg/day group who received topiramate as monotherapy in Study 1 discontinued therapy due to adverse reactions. The most common (≥2% more frequent than low-dose 50 mg/day topiramate) adverse reactions causing discontinuation were difficulty with memory, fatigue, asthenia, insomnia, somnolence, and paresthesia. Pediatric Patients 6 Years to 15 Years of Age The most common adverse reactions in the controlled trial (Study 1) that occurred in pediatric patients in the 400 mg/day topiramate group and at an incidence higher (≥10%) than in the 50 mg/day group were fever and weight loss (see Table 3 ).

Approximately 14% of the 77 pediatric patients in the 400 mg/day group who received topiramate as monotherapy in the controlled clinical trial discontinued therapy due to adverse reactions. The most common (≥2% more frequent than in the 50 mg/day group…

7 DRUG INTERACTIONS Contraceptives: Decreased contraceptive efficacy and increased breakthrough bleeding, especially at doses greater than 200 mg per day ( 7.5 ) Monitor lithium levels if lithium is used with high-dose TROKENDI XR ( 7.8 )

7.1Alcohol Alcohol use is contraindicated within 6 hours prior to and 6 hours after TROKENDI XR administration [see Contraindications (4) and Warnings and Precautions (5.5) ].

7.2Antiepileptic Drugs Concomitant administration of phenytoin or carbamazepine with topiramate resulted in a clinically significant decrease in plasma concentrations of topiramate when compared to topiramate given alone. A dosage adjustment may be needed [see Dosage and Administration (2.1) , Clinical Pharmacology (12.3) ]. Concomitant administration of valproic acid and topiramate has been associated with hypothermia and hyperammonemia with and without encephalopathy.

Examine blood ammonia levels in patients in whom the onset of hypothermia has been reported [see Warnings and Precautions (5.15 , 5.17) and Clinical Pharmacology (12.3) ] .

7.3Other Carbonic Anhydrase Inhibitors Concomitant use of topiramate, a carbonic anhydrase inhibitor, with any other carbonic anhydrase inhibitor (e.g., zonisamide or acetazolamide) may increase the severity of metabolic acidosis and may also increase the risk of kidney stone formation. Patients should be monitored for the appearance or worsening of metabolic acidosis when TROKENDI XR is given concomitantly with another carbonic anhydrase inhibitor [see Clinical Pharmacology (12.3) ].

7.4CNS Depressants Concomitant administration of topiramate with other CNS depressant drugs or alcohol has not been evaluated in clinical studies. Because of the potential of topiramate to cause CNS depression, as well as other cognitive and/or neuropsychiatric adverse reactions, TROKENDI XR should be used with extreme caution if used in combination with alcohol and other CNS depressants [see Contraindications (4) and Warnings and Precautions (5.7) ].

7.5Contraceptives The possibility of decreased contraceptive efficacy and increased breakthrough bleeding may occur in patients taking contraceptive products with TROKENDI XR. Patients taking estrogen-containing or progestin-only contraceptives should be asked to report any change in their bleeding patterns. Contraceptive efficacy can be decreased even in the absence of breakthrough bleeding [see Clinical Pharmacology (12.3) ] .

7.6Hydrochlorothiazide (HCTZ) Topiramate C max and AUC increased when HCTZ was added to immediate-release topiramate. The clinical significance of this change is unknown. The addition of HCTZ to TROKENDI XR may require a decrease in the TROKENDI XR dose [see Clinical Pharmacology (12.3) ] .

7.7Pioglitazone A decrease in the exposure of pioglitazone and its active metabolites were noted with the concurrent use of pioglitazone and immediate-release topiramate in a clinical trial. The clinical relevance of these observations is unknown; however, when TROKENDI XR is added to pioglitazone therapy or pioglitazone is added to TROKENDI XR therapy, careful attention should be given to the routine monitoring of patients for adequate control of their diabetic disease state [see Clinical Pharmacology (12.3) ] .

7.8Lithium An increase in systemic exposure of lithium following topiramate doses of up to 600 mg/day can occur. Lithium levels should be monitored when co-administered with high-dose TROKENDI XR [see Clinical Pharmacology (12.3) ].

7.9Amitriptyline Some patients may experience a large increase in amitriptyline concentration in the presence of TROKENDI XR and any adjustments in amitriptyline dose should be made according to the patients' clinical response and not on the basis of plasma levels [see Clinical Pharmacology (12.3) ] .

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as TROKENDI XR, during pregnancy. Patients should be encouraged to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy.

To enroll, patients can call the toll-free number 1-888-233-2334. Information about the North American Drug Pregnancy Registry can be found at http://www.aedpregnancyregistry.org/. Risk Summary TROKENDI XR can cause fetal harm when administered to a pregnant woman.

Data from pregnancy registries indicate that infants exposed to topiramate in utero have increased risk of major congenital malformations, including but not limited to cleft lip and/or cleft palate (oral clefts), and of being small for gestational age (SGA) [see Human Data ] . SGA has been observed at all doses and appears to be dose-dependent. The prevalence of SGA is greater in infants of women who received higher doses of topiramate during pregnancy.

In addition, the prevalence of SGA in infants of women who continued topiramate use until later in pregnancy is higher compared to the prevalence in infants of women who stopped topiramate use before the third trimester. In multiple animal species, topiramate demonstrated developmental toxicity, including increased incidences of fetal malformations, in the absence of maternal toxicity at clinically relevant doses [see Animal Data ] . All pregnancies have a background risk of birth defects, loss, or other adverse outcomes.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal Adverse reactions Consider the benefits and risks of topiramate when prescribing this drug to women of childbearing potential, particularly when topiramate is considered for a condition not usually associated with permanent injury or death.

Because of the risk of oral clefts to the fetus, which occur in the first trimester of pregnancy before many women know they are pregnant, all women of childbearing potential should be informed of the potential risk to the fetus from exposure to topiramate. Women who are planning a pregnancy should be counseled regarding the relative risks and benefits of topiramate use during pregnancy, and alternative therapeutic options should be considered for these patients. Labor or Delivery Although the effect of topiramate on labor and delivery in humans has not been established, the development of topiramate-induced metabolic acidosis in the mother and/or in the fetus might affect the fetus' ability to tolerate labor.

TROKENDI XR treatment can cause metabolic acidosis [see Warnings and Precautions (5.4) ] . The effect of topiramate-induced metabolic acidosis has not been studied in pregnancy; however, metabolic acidosis in pregnancy (due to other causes) can cause decreased fetal growth, decreased fetal oxygenation, and fetal death, and may affect the fetus' ability to tolerate labor. Pregnant patients should be monitored for metabolic acidosis and treated as in the nonpregnant state [see Warnings and Precautions (5.4) ] .

Newborns of mothers treated with TROKENDI XR should be monitored for metabolic acidosis because of transfer of topiramate to the fetus and possible occurrence of transient metabolic acidosis following birth. Based on limited information, topiramate has also been associated with pre-term labor and premature delivery. Data Human Data Data from pregnancy registries indicate an increased risk of major congenital malformations, including but not limited to oral clefts in infants exposed…

🧒 Pediatric Use ~3 min read ▾

8.4Pediatric Use Seizures in Pediatric Patients 6 Years of Age and Older The safety and effectiveness of TROKENDI XR for treatment of partial onset seizures, primary generalized tonic-clonic seizures, or Lennox-Gastaut syndromes in pediatric patients at least 6 years of age is based on controlled trials with immediate-release topiramate [see Adverse Reactions (6.1) , Clinical Studies (14.2 , 14.3) ] . The adverse reactions in pediatric patients treated for partial onset seizure, primary generalized tonic-clonic seizures, or Lennox-Gastaut syndrome are similar to those seen in adults [see Warnings and Precautions (5) and Adverse Reactions (6) ] .

These include, but are not limited to: oligohydrosis and hyperthermia [see Warnings and Precautions (5.3) ] dose-related increased incidence of metabolic acidosis [see Warnings and Precautions (5.4) ] dose-related increased incidence of hyperammonemia [see Warnings and Precautions (5.15) ] Not Recommended for Pediatric Patients Younger than 6 Years of Age The safety and effectiveness of TROKENDI XR for treatment of partial-onset seizures, primary generalized tonic-clonic seizures, or Lennox-Gastaut syndromes in pediatric patients younger than 6 years of age have not been established.

Because the capsule must be swallowed whole, and may not be sprinkled on food, crushed or chewed, TROKENDI XR is recommended only for children age 6 or older. The following pediatric use information for adjunctive treatment for partial onset epilepsy in infants and toddlers (1 to 24 months) is based on studies conducted with immediate-release topiramate, which failed to demonstrate efficacy. Safety and effectiveness of immediate-release topiramate in patients below the age of 2 years have not been established for the adjunctive therapy treatment of partial onset seizures, primary generalized tonic-clonic seizures, or seizures associated with Lennox-Gastaut syndrome.

In a single randomized, double-blind, placebo-controlled investigational trial, the efficacy, safety, and tolerability of immediate-release topiramate oral liquid and sprinkle formulations as an adjunct to concurrent antiepileptic drug therapy in pediatric patients 1 to 24 months of age with refractory partial-onset seizures were assessed. After 20 days of double-blind treatment, immediate-release topiramate (at fixed doses of 5, 15, and 25 mg/kg per day) did not demonstrate efficacy compared with placebo in controlling seizures.

In general, the adverse reaction profile for immediate-release topiramate in this population was similar to that of older pediatric patients, although results from the above controlled study, and an open-label, long-term extension study in these pediatric patients 1 to 24 months old suggested some adverse reactions not previously observed in older pediatric patients and adults; i.e., growth/length retardation, certain clinical laboratory abnormalities, and other adverse reactions that occurred with a greater frequency and/or greater severity than had been recognized previously from studies in older pediatric patients or adults for various indications.

These very young pediatric patients appeared to experience an increased risk for infections (any topiramate dose 12%, placebo 0%) and of respiratory disorders (any topiramate dose 40%, placebo 16%). The following adverse reactions were observed in at least 3% of patients on immediate-release topiramate and were 3% to 7% more frequent than in patients on placebo: viral infection, bronchitis, pharyngitis, rhinitis, otitis media, upper respiratory infection, cough, and bronchospasm. A generally similar profile was observed in older pediatric patients [see Adverse Reactions (6.1) ].

Immediate-release topiramate resulted in an increased incidence of patients with increased creatinine (any topiramate dose 5%, placebo 0%), BUN (any topiramate dose 3%, placebo 0%), and protein (any topiramate dose 34%, placebo 6%), and an increased incidence of decreased potassium (any topiramat…

🧓 Geriatric Use 64 words ▾

8.5Geriatric Use Clinical studies of immediate-release topiramate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. Dosage adjustment may be necessary for elderly with creatinine clearance less than 70 mL/min/1.73 m 2 . Estimate GFR should be measured prior to dosing [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3) ] .

🆘 Overdosage 151 words ▾

10 OVERDOSAGE Overdoses of topiramate have been reported. Signs and symptoms included convulsions, drowsiness, speech disturbance, blurred vision, diplopia, impaired mentation, lethargy, abnormal coordination, stupor, hypotension, abdominal pain, agitation, dizziness, and depression. The clinical consequences were not severe in most cases, but deaths have been reported after overdoses involving topiramate.

Topiramate overdose has resulted in severe metabolic acidosis [see Warnings and Precautions (5.4) ] . A patient who ingested a dose of immediate-release topiramate between 96 g and 110 g was admitted to a hospital with a coma lasting 20 to 24 hours followed by full recovery after 3 to 4 days. Similar signs, symptoms, and clinical consequences are expected to occur with overdosage of TROKENDI XR.

In the event of overdose, TROKENDI XR should be discontinued and general supportive treatment given until clinical toxicity has been diminished or resolved. Hemodialysis is an effective means of removing topiramate from the body.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The precise mechanisms by which topiramate exerts its anticonvulsant and preventive migraine effects are unknown; however, preclinical studies have revealed four properties that may contribute to topiramate's efficacy for epilepsy and the preventive treatment of migraine. Electrophysiological and biochemical evidence suggests that topiramate, at pharmacologically relevant concentrations, blocks voltage-dependent sodium channels, augments the activity of the neurotransmitter gamma-aminobutyrate at some subtypes of the GABA-A receptor, antagonizes the AMPA/kainate subtype of the glutamate receptor, and inhibits the carbonic anhydrase enzyme, particularly isozymes II and IV.

12.2Pharmacodynamics Topiramate has anticonvulsant activity in rat and mouse maximal electroshock seizure (MES) tests. Topiramate is only weakly effective in blocking clonic seizures induced by the GABA-A receptor antagonist, pentylenetetrazole. Topiramate is also effective in rodent models of epilepsy, which include tonic and absence-like seizures in the spontaneous epileptic rat (SER) and tonic and clonic seizures induced in rats by kindling of the amygdala or by global ischemia.

Changes (increases and decreases) from baseline in vital signs (systolic blood pressure-SBP, diastolic blood pressure-DBP, pulse) occurred more frequently in pediatric patients (6 to 17 years) treated with various daily doses of topiramate (50 mg, 100 mg, 200 mg, 2 to 3 mg/kg) than in patients treated with placebo in controlled trials for the preventive treatment of migraine. The most notable changes were SBP <90 mm Hg, DBP <50 mm Hg, SBP or DBP increases or decreases ≥20 mm Hg, and pulse increases or decreases ≥30 beats per minute.

These changes were often dose-related, and were most frequently associated with the greatest treatment difference at the 200 mg dose level. Systematic collection of orthostatic vital signs has not been conducted. The clinical significance of these various changes in vital signs has not been clearly established.

12.3Pharmacokinetics Absorption and Distribution Linear pharmacokinetics of topiramate from TROKENDI XR were observed following a single oral dose over the range of 50 mg to 200 mg. At 25 mg, the pharmacokinetics of TROKENDI XR is nonlinear possibly due to the binding of topiramate to carbonic anhydrase in red blood cells. The peak plasma concentrations (C max ) of topiramate occurred at approximately 24 hours following a single 200 mg oral dose of TROKENDI XR.

At steady-state, the (AUC 0-24 , C max , and C min ) of topiramate from TROKENDI XR administered once-daily and the immediate-release tablet administered twice-daily were shown to be bioequivalent. Fluctuation of topiramate plasma concentrations at steady-state for TROKENDI XR administered once-daily was approximately 26% and 42% in healthy subjects and in epileptic patients, respectively, compared to approximately 40% and 51%, respectively, for immediate-release topiramate [see Clinical Pharmacology (12.6) ] . Compared to the fasted state, high-fat meal increased the C max of topiramate by 37% and shortened the T max to approximately 8 hours following a single dose of TROKENDI XR, while having no effect on the AUC.

Modeling of the observed single dose fed data with simulation to steady state showed that the effect on C max is significantly reduced following repeat administrations. TROKENDI XR can be taken without regard to meals. Topiramate is 15% to 41% bound to human plasma proteins over the blood concentration range of 0.5 mcg/mL to 250 mcg/mL.

The fraction bound decreased as blood concentration increased. Carbamazepine and phenytoin do not alter the binding of immediate-release topiramate. Sodium valproate, at 500 mcg/mL (a concentration 5 to 10 times higher than considered therapeutic for valproate) decreased the protein binding of immediate-release topiramate from 23% to 13%.

Immediate-release topiramate does not influence the bind…

💬 Information for Patients ~3 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide). Administration Instructions Counsel patients to swallow TROKENDI XR capsules whole and intact. TROKENDI XR should not be sprinkled on food, chewed, or crushed [see Dosage and Administration (2.7)] .

Consumption of Alcohol Advise patients to completely avoid consumption of alcohol at least 6 hours prior to and 6 hours after taking TROKENDI XR [see Warnings and Precautions (5.5) ] . Eye Disorders Advise patients taking TROKENDI XR to seek immediate medical attention if they experience blurred vision, visual disturbances, or periorbital pain [see Warnings and Precautions (5.1 , 5.2) ] . Oligohydrosis and Hyperthermia Counsel patients that TROKENDI XR, especially pediatric patients, can cause decreased sweating and increased body temperature, especially in hot weather, and they should seek medical attention if this is noticed [see Warnings and Precautions (5.3) ] .

Metabolic Acidosis Inform patients about the potentially significant risk for metabolic acidosis that may be asymptomatic and may be associated with adverse effects on kidneys (e.g., kidney stones, nephrocalcinosis), bones (e.g., osteoporosis, osteomalacia, and/or rickets in children), and growth (e.g., growth delay/retardation) in pediatric patients, and on the fetus [see Warnings and Precautions (5.4) ] . Suicidal Behavior and Ideation Counsel patients, their caregivers, and families that AEDs, including TROKENDI XR, may increase the risk of suicidal thoughts and behavior and they should be advised of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior or the emergence of suicidal thoughts, behavior, or thoughts about self-harm.

Behaviors of concern should be reported immediately to healthcare providers [see Warnings and Precautions (5.6) ]. Interference With Cognitive and Motor Performance Warn patients about the potential for somnolence, dizziness, confusion, difficulty concentrating, or visual effects and advise them not to drive or operate machinery until they have gained sufficient experience on TROKENDI XR to gauge whether it adversely affects their mental performance, motor performance, and/or vision [see Warnings and Precautions (5.7) ] .

Advise patients that even when taking TROKENDI XR or other anticonvulsants, some patients with epilepsy will continue to have unpredictable seizures. Therefore, counsel all patients taking TROKENDI XR for epilepsy to exercise appropriate caution when engaging in any activities where loss of consciousness could result in serious danger to themselves or those around them (including swimming, driving a car, climbing in high places, etc.). Some patients with refractory epilepsy will need to avoid such activities altogether.

Physicians should discuss the appropriate level of caution with their patients, before patients with epilepsy engage in such activities. Fetal Toxicity Counsel pregnant women and women of childbearing potential that use of TROKENDI XR during pregnancy can cause fetal harm. TROKENDI increases the risk of major congenital malformations, including but not limited to cleft lip and/or cleft palate (oral clefts), which occur early in pregnancy before many women know they are pregnant.

Also inform patients that infants exposed to topiramate monotherapy in utero may be SGA [see Use in Specific Populations (8.1) ] . There may also be risks to the fetus from chronic metabolic acidosis with use of TROKENDI XR during pregnancy [see Warnings and Precautions (5.4 , 5.8) ]. When appropriate, prescribers should counsel pregnant women and women of childbearing potential about alternative therapeutic options.

Advise women of childbearing potential who are not planning a pregnancy to use effective contraception while using topiramate, keeping in mind that there is a potential for decreased contraceptive efficacy when using estrogen-cont…

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: 3/2026 MEDICATION GUIDE TROKENDI XR ® (tro-KEN-dee eks ahr) (topiramate) Extended-Release Capsules What is the most important information I should know about Trokendi XR?

Take Trokendi XR capsules whole. Do not sprinkle Trokendi XR on food, or break, crush, dissolve, or chew Trokendi XR capsules before swallowing. If you cannot swallow Trokendi XR capsules whole, tell your healthcare provider.

You may need a different medicine. Do not drink alcohol within 6 hours prior to and 6 hours after Trokendi XR administration. Trokendi XR may cause eye problems.

Serious eye problems include: any sudden decrease in vision with or without eye pain and redness, a blockage of fluid in the eye causing increased pressure in the eye (secondary angle closure glaucoma). These eye problems can lead to permanent loss of vision if not treated. You should call your healthcare provider right away if you have any new eye symptoms, including any new problems with your vision.

Trokendi XR may cause decreased sweating and increased body temperature (fever). People, especially children, should be watched for signs of decreased sweating and fever, especially in hot temperatures. Some people may need to be hospitalized for this condition.

If a high fever, a fever that does not go away, or decreased sweating develops, call your healthcare provider right away. Trokendi XR can increase the level of acid in your blood (metabolic acidosis). If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant.

Metabolic acidosis can happen with or without symptoms. Sometimes people with metabolic acidosis will: feel tired not feel hungry (loss of appetite) feel changes in heartbeat have trouble thinking clearly Your healthcare provider should do a blood test to measure the level of acid in your blood before and during your treatment with Trokendi XR. If you are pregnant, you should talk to your healthcare provider about whether you have metabolic acidosis.

Like other antiepileptic drugs, Trokendi XR may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you: thoughts about suicide or dying attempts to commit suicide new or worse depression new or worse anxiety feeling agitated or restless panic attacks trouble sleeping (insomnia) new or worse irritability acting aggressive, being angry, or violent acting on dangerous impulses an extreme increase in activity and talking (mania) other unusual changes in behavior or mood Do not stop Trokendi XR without first talking to a healthcare provider.

Stopping Trokendi XR suddenly can cause serious problems. Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

How can I watch for early symptoms of suicidal thoughts and actions? Pay attention to any changes, especially sudden changes in mood, behaviors, thoughts, or feelings. Keep all follow-up visits with your healthcare provider as scheduled.

Call your healthcare provider between visits as needed, especially if you are worried about symptoms. Trokendi XR can harm your unborn baby. If you take Trokendi XR during pregnancy, your baby has a higher risk for birth defects including cleft lip and cleft palate.

These defects can begin early in pregnancy, even before you know you are pregnant. Birth defects may happen even in children born to women who are not taking any medicines and do not have other risk factors. There may be other medicines to treat your condition that have a lower chance of birth defects.

All women of childbearing age should talk to their healthcare providers a…
