Why two NDCs? The FDA registers this code as 0078-0337-05 — a 4-4-2 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 labeler segment → 00078-0337-05. Same drug, same package — only the format differs.

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.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 00078-0337-05, not the drug overall. Other pack sizes report separately.

💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

📅 Q1 2025 – Q4 2025 · 4 quarters of data

💊 Medicaid utilization by pack size

Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

Medicare Part D (outpatient prescription) spending for Trileptal — 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 Trileptal. 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.

🎯 Indications and Usage 98 words ▾

1 INDICATIONS AND USAGE TRILEPTAL is indicated for use as monotherapy or adjunctive therapy in the treatment of partial-onset seizures in adults and as monotherapy in the treatment of partial-onset seizures in pediatric patients aged 4 years and above, and as adjunctive therapy in pediatric patients aged 2 years and above with partial-onset seizures. TRILEPTAL is indicated for: Adults: Monotherapy or adjunctive therapy in the treatment of partial-onset seizures Pediatrics: - Monotherapy in the treatment of partial-onset seizures in children 4-16 years - Adjunctive therapy in the treatment of partial-onset seizures in children 2-16 years ( 1 )

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Adults: Initiate with a dose of 600 mg/day, given twice a day Adjunctive Therapy: Maximum increment of 600 mg/day at approximately weekly intervals. The recommended daily dose is 1200 mg/day ( 2.1 ) Conversion to Monotherapy: Withdrawal concomitant over 3 to 6 weeks; reach maximum dose of TRILEPTAL in 2 to 4 weeks with increments of 600 mg/day at weekly intervals to a recommended daily dose of 2400 mg/day ( 2.2 ) Initiation of Monotherapy: Increments of 300 mg/day every third day to a dose of 1200 mg/day ( 2.3 ) Initiate at one-half the usual starting dose and increase slowly in patients with a creatinine clearance < 30 mL/min ( 2.7 ) Pediatrics : Initiation with 8 to 10 mg/kg/day, given twice a day.

For patients aged 2 to < 4 years and under 20 kg, a starting dose of 16 to 20 mg/kg/day may be considered. Recommended daily dose is dependent upon patient weight. Adjunctive Patients (Aged 2-16 Years): For patients aged 4 to 16 years, target maintenance dose should be achieved over 2 weeks ( 2.4 ).

For patients aged 2 to < 4 years, maximum maintenance dose should be achieved over 2 to 4 weeks and should not exceed 60 mg/kg/day ( 2.4 ) Conversion to Monotherapy for Patients (Aged 4-16 Years): Maximum increment of 10 mg/kg/day at weekly intervals, concomitant antiepileptic drugs (AEDs) can be completely withdrawn over 3 to 6 weeks ( 2.5 ) Initiation of Monotherapy for Patients (Aged 4-16 Years): Increments of 5 mg/kg/day every third day ( 2.6 )

2.1Adjunctive Therapy for Adults Initiate TRILEPTAL with a dose of 600 mg/day, given twice a day. If clinically indicated, the dose may be increased by a maximum of 600 mg/day at approximately weekly intervals; the maximum recommended daily dose is 1200 mg/day. Daily doses above 1200 mg/day show somewhat greater effectiveness in controlled trials, but most patients were not able to tolerate the 2400 mg/day dose, primarily because of central nervous (CNS) effects.

Dosage adjustment is recommended with concomitant use of strong CYP3A4 enzyme inducers or UDP-glucuronosyltransferases (UGT) inducers, which include certain antiepileptic drugs (AEDs) [ see Drug Interactions (7.1, 7.2) ].

2.2Conversion to Monotherapy for Adults Patients receiving concomitant AEDs may be converted to monotherapy by initiating treatment with TRILEPTAL at 600 mg/day (given in a twice a day regimen) while simultaneously initiating the reduction of the dose of the concomitant AEDs. The concomitant AEDs should be completely withdrawn over 3 to 6 weeks, while the maximum dose of TRILEPTAL should be reached in about 2 to 4 weeks. TRILEPTAL may be increased as clinically indicated by a maximum increment of 600 mg/day at approximately weekly intervals to achieve the maximum recommended daily dose of 2400 mg/day.

A daily dose of 1200 mg/day has been shown in one study to be effective in patients in whom monotherapy has been initiated with TRILEPTAL. Patients should be observed closely during this transition phase.

2.3Initiation of Monotherapy for Adults Patients not currently being treated with AEDs may have monotherapy initiated with TRILEPTAL. In these patients, initiate TRILEPTAL at a dose of 600 mg/day (given twice a day); the dose should be increased by 300 mg/day every third day to a dose of 1200 mg/day. Controlled trials in these patients examined the effectiveness of a 1200 mg/day dose; a dose of 2400 mg/day has been shown to be effective in patients converted from other AEDs to TRILEPTAL monotherapy (see above).

2.4Adjunctive Therapy for Pediatric Patients (Aged 2-16 Years) In pediatric patients aged 4-16 years, initiate TRILEPTAL at a daily dose of 8 to 10 mg/kg generally not to exceed 600 mg/day, given twice a day. The target maintenance dose of TRILEPTAL should be achieved over 2 weeks, and is dependent upon patient weight, according to the following chart: 20 to 29 kg-900 mg/day 29.1 to 39 kg-1200 mg/day 39 kg-1800 mg/day In the clinical trial, in which the intention was to reach th…

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Hyponatremia: Monitor serum sodium levels ( 5.1 ) Cross Hypersensitivity Reaction to Carbamazepine: Discontinue immediately if hypersensitivity occurs ( 5.3 ) Serious Dermatological Reactions: If occurs, consider discontinuation ( 5.4 ) Suicidal Behavior and Ideation: Monitor for suicidal thoughts/behavior ( 5.5 ) Withdrawal of AEDs: Withdraw TRILEPTAL gradually ( 5.6 ) Cognitive/Neuropsychiatric Adverse Reactions: May cause cognitive dysfunction, somnolence, and coordination abnormalities.

Use caution when operating machinery ( 5.7 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multi-Organ Hypersensitivity: Monitor and discontinue if another cause cannot be established ( 5.8 ) Hematologic Events: Consider discontinuing ( 5.9 ) Seizure Control During Pregnancy: Active metabolite may decrease ( 5.10 ) Risk of Seizure Aggravation: Discontinue if occurs ( 5.11 )

5.1Hyponatremia Clinically significant hyponatremia (sodium < 125 mmol/L) can develop during TRILEPTAL use. In the 14 controlled epilepsy studies, 2.5% of TRILEPTAL-treated patients (38/1524) had a sodium of less than 125 mmol/L at some point during treatment, compared to no such patients assigned placebo or active control (carbamazepine and phenobarbital for adjunctive and monotherapy substitution studies, and phenytoin and valproate for the monotherapy initiation studies). Clinically significant hyponatremia generally occurred during the first 3 months of treatment with TRILEPTAL, although there were patients who first developed a serum sodium < 125 mmol/L more than 1 year after initiation of therapy.

Most patients who developed hyponatremia were asymptomatic, but patients in the clinical trials were frequently monitored and some had their TRILEPTAL dose reduced, discontinued, or had their fluid intake restricted for hyponatremia. Whether or not these maneuvers prevented the occurrence of more severe events is unknown. Cases of symptomatic hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH) have been reported during postmarketing use.

In clinical trials, patients whose treatment with TRILEPTAL was discontinued due to hyponatremia generally experienced normalization of serum sodium within a few days without additional treatment. Measurement of serum sodium levels should be considered for patients during maintenance treatment with TRILEPTAL, particularly if the patient is receiving other medications known to decrease serum sodium levels (e.g., drugs associated with inappropriate ADH secretion), or if symptoms possibly indicating hyponatremia develop (e.g., nausea, malaise, headache, lethargy, confusion, obtundation, or increase in seizure frequency or severity).

5.2Anaphylactic Reactions and Angioedema Rare cases of anaphylaxis and angioedema involving the larynx, glottis, lips and eyelids have been reported in patients after taking the first or subsequent doses of TRILEPTAL. Angioedema associated with laryngeal edema can be fatal. If a patient develops any of these reactions after treatment with TRILEPTAL, the drug should be discontinued and an alternative treatment started.

These patients should not be rechallenged with the drug [ see Warnings and Precautions (5.3) ].

5.3Cross Hypersensitivity Reaction to Carbamazepine Approximately 25% to 30% of patients who have had hypersensitivity reactions to carbamazepine will experience hypersensitivity reactions with TRILEPTAL. For this reason, patients should be specifically questioned about any prior experience with carbamazepine, and patients with a history of hypersensitivity reactions to carbamazepine should ordinarily be treated with TRILEPTAL only if the potential benefit justifies the potential risk. If signs or symptoms of hypersensitivity develop, TRILEPTAL should be discontinued immediately [ see Warnings and Precautions (5.2, 5.8) ].

7 DRUG INTERACTIONS Phenytoin: Increased phenytoin levels. Reduced dose of phenytoin may be required ( 7.1 ) Carbamazepine, Phenytoin, and Phenobarbital: Decreased plasma levels of MHD (the active metabolite). Dose adjustments may be necessary ( 7.1 ) Oral Contraceptive: TRILEPTAL may decrease the effectiveness of hormonal contraceptives ( 7.3 )

7.1Effect of TRILEPTAL on Other Drugs Phenytoin levels have been shown to increase with concomitant use of TRILEPTAL at doses greater than 1200 mg/day [see Clinical Pharmacology (12.3)] . Therefore, it is recommended that the plasma levels of phenytoin be monitored during the period of TRILEPTAL titration and dosage modification. A decrease in the dose of phenytoin may be required.

7.2Effect of Other Drugs on TRILEPTAL Strong inducers of cytochrome P450 enzymes and/or inducers of UGT (e.g., rifampin, carbamazepine, phenytoin and phenobarbital) have been shown to decrease the plasma/serum levels of MHD, the active metabolite of TRILEPTAL (25% to 49%) [see Clinical Pharmacology (12.3)] . If TRILEPTAL and strong CYP3A4 inducers, or UGT inducers are administered concurrently, it is recommended that the plasma levels of MHD be monitored during the period of TRILEPTAL titration. Dose adjustment of TRILEPTAL may be required after initiation, dosage modification, or discontinuation of such inducers.

7.3Hormonal Contraceptives Concurrent use of TRILEPTAL with hormonal contraceptives may render these contraceptives less effective [see Use in Specific Populations (8.3) and Clinical Pharmacology (12.3)] . Studies with other oral or implant contraceptives have not been conducted.

8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause fetal harm ( 8.1)

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to AEDs, such as TRILEPTAL, during pregnancy. Encourage women who are taking TRILEPTAL during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. Risk Summary Although TRILEPTAL is closely related structurally to carbamazepine, which is considered to be teratogenic in humans, available human data from published literature and ongoing pregnancy registry studies on use of oxcarbazepine during pregnancy have not demonstrated an increased prevalence of major congenital malformations with first trimester exposure.

However, all published studies reviewed have important methodological limitations, including unmeasured confounding and a small number of exposed cases ( see Data ). There are risks to the mother and fetus associated with partial onset seizures ( see Clinical Considerations ). There are no data on the risks associated with the use of TRILEPTAL and miscarriage or other adverse maternal outcomes.

Increased incidences of fetal structural abnormalities and other manifestations of developmental toxicity (embryolethality, growth retardation) were observed in the offspring of animals treated with either oxcarbazepine or its active 10-hydroxy metabolite (MHD) during pregnancy at doses similar to the maximum recommended human dose (MRHD). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. Clinical Considerations Disease-associated Maternal and/or Embryofetal Risk Epilepsy, with or without exposure to antiepileptic drugs, has been associated with several adverse outcomes during pregnancy, including preeclampsia, preterm labor, antepartum and postpartum hemorrhage, placental abruption, poor fetal growth, prematurity, fetal death, and maternal mortality. The risk of maternal or fetal injury may be greatest for patients with untreated or poorly controlled convulsive seizures.

Women with epilepsy who become pregnant should not abruptly discontinue antiepileptic drugs, including TRILEPTAL, due to the risk of status epilepticus or severe seizures, which may be life-threatening [see Warnings and Precautions (5.6)] . Maternal Adverse Reactions An increase in seizure frequency may occur during pregnancy because of altered levels of the active metabolite of oxcarbazepine. Monitor patients carefully during pregnancy and through the postpartum period [see Warnings and Precautions (5.10)] .

Data Human Data Data from a published retrospective cohort study and ongoing pregnancy registry studies on the use of oxcarbazepine during pregnancy have not demonstrated an increased prevalence of major congenital malformations with first trimester exposure. A retrospective cohort study conducted in Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) from 1996-2020 found that there was no increased prevalence of major congenital malformations when pregnancies exposed to oxcarbazepine during the first trimester were compared to pregnancies exposed to lamotrigine (adjusted risk ratio =1.09; 95% CI 0.83 to 1.44; n pregnancies exposed to oxcarbazepine= 1,313, n exposed cases = 58).

In an ongoing pregnancy registry that included data from over 40 countries from 1999 to 2022 and 443 pregnancies exposed to oxcarbazepine, oxcarbazepine exposure during the first trimester was not associated with major congenital malformations (adjusted odds ratio =1.09; 95% CI 0.56 to 2.13, n exposed cases = 10). However, there are important methodological limitations of these studies including unmeasured confounding factors and a small number of exp…

🧒 Pediatric Use 144 words ▾

8.4Pediatric Use TRILEPTAL is indicated for use as adjunctive therapy for partial-onset seizures in patients aged 2 to 16 years. The safety and effectiveness for use as adjunctive therapy for partial-onset seizures in pediatric patients below the age of 2 have not been established. TRILEPTAL is also indicated as monotherapy for partial-onset seizures in patients aged 4 to 16 years.

The safety and effectiveness for use as monotherapy for partial-onset seizures in pediatric patients below the age of 4 have not been established. TRILEPTAL has been given to 898 patients between the ages of 1 month to 17 years in controlled clinical trials (332 treated as monotherapy) and about 677 patients between the ages of 1 month to 17 years in other trials [ s ee Warnings and Precautions (5.11), Adverse Reactions (6.1) , Clinical Pharmacology (12.3), and Clinical Studies (14 ) ].

🧓 Geriatric Use 117 words ▾

8.5Geriatric Use There were 52 patients over age 65 in controlled clinical trials and 565 patients over the age of 65 in other trials. Following administration of single (300 mg) and multiple (600 mg/day) doses of TRILEPTAL in elderly volunteers (60 to 82 years of age), the maximum plasma concentrations and area under the curve (AUC) values of MHD were 30% to 60% higher than in younger volunteers (18 to 32 years of age). Comparisons of creatinine clearance in young and elderly volunteers indicate that the difference was due to age-related reductions in creatinine clearance.

Close monitoring of sodium levels is required in elderly patients at risk for hyponatremia [ see Warnings and Precautions (5.1) ].

🆘 Overdosage 105 words ▾

10 OVERDOSAGE

10.1Human Overdose Experience Isolated cases of overdose with TRILEPTAL have been reported. The maximum dose taken was approximately 48,000 mg. All patients recovered with symptomatic treatment.

Nausea, vomiting, somnolence, aggression, agitation, hypotension, and tremor each occurred in more than one patient. Coma, confusional state, convulsion, dyscoordination, depressed level of consciousness, diplopia, dizziness, dyskinesia, dyspnea, QT prolongation, headache, miosis, nystagmus, overdose, decreased urine output, and blurred vision also occurred.

10.2Treatment and Management There is no specific antidote. Symptomatic and supportive treatment should be administered as appropriate. Removal of the drug by gastric lavage and/or inactivation by administering activated charcoal should be considered.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The pharmacological activity of TRILEPTAL is primarily exerted through the 10-monohydroxy metabolite (MHD) of oxcarbazepine [ see Clinical Pharmacology (12.3) ]. The precise mechanism by which oxcarbazepine and MHD exert their anti-seizure effect is unknown; however, in vitro electrophysiological studies indicate that they produce blockade of voltage-sensitive sodium channels, resulting in stabilization of hyperexcited neural membranes, inhibition of repetitive neuronal firing, and diminution of propagation of synaptic impulses.

These actions are thought to be important in the prevention of seizure spread in the intact brain. In addition, increased potassium conductance and modulation of high-voltage activated calcium channels may contribute to the anticonvulsant effects of the drug. No significant interactions of oxcarbazepine or MHD with brain neurotransmitter or modulator receptor sites have been demonstrated.

12.2Pharmacodynamics Oxcarbazepine and its active metabolite (MHD) exhibit anticonvulsant properties in animal seizure models. They protected rodents against electrically induced tonic extension seizures and, to a lesser degree, chemically induced clonic seizures, and abolished or reduced the frequency of chronically recurring focal seizures in Rhesus monkeys with aluminum implants. No development of tolerance (i.e., attenuation of anticonvulsive activity) was observed in the maximal electroshock test when mice and rats were treated daily for 5 days and 4 weeks, respectively, with oxcarbazepine or MHD.

12.3Pharmacokinetics Following oral administration of TRILEPTAL tablets, oxcarbazepine is completely absorbed and extensively metabolized to its pharmacologically active 10-monohydroxy metabolite (MHD). In a mass balance study in people, only 2% of total radioactivity in plasma was due to unchanged oxcarbazepine, with approximately 70% present as MHD, and the remainder attributable to minor metabolites. The half-life of the parent is about 2 hours, while the half-life of MHD is about 9 hours, so that MHD is responsible for most antiepileptic activity.

Absorption Based on MHD concentrations, TRILEPTAL tablets and suspension were shown to have similar bioavailability. After single-dose administration of TRILEPTAL tablets to healthy male volunteers under fasted conditions, the median t max was 4.5 (range, 3 to 13) hours. After single-dose administration of TRILEPTAL oral suspension to healthy male volunteers under fasted conditions, the median t max was 6 hours.

Steady-state plasma concentrations of MHD are reached within 2 to 3 days in patients when TRILEPTAL is given twice a day. At steady state the pharmacokinetics of MHD are linear and show dose proportionality over the dose range of 300 to 2400 mg/day. Food has no effect on the rate and extent of absorption of oxcarbazepine from TRILEPTAL tablets.

Although not directly studied, the oral bioavailability of the TRILEPTAL suspension is unlikely to be affected under fed conditions. Therefore, TRILEPTAL tablets and suspension can be taken with or without food. Distribution The apparent volume of distribution of MHD is 49 L.

Approximately 40% of MHD is bound to serum proteins, predominantly to albumin. Binding is independent of the serum concentration within the therapeutically relevant range. Oxcarbazepine and MHD do not bind to alpha-1-acid glycoprotein.

Metabolism and Excretion Oxcarbazepine is rapidly reduced by cytosolic enzymes in the liver to its 10-monohydroxy metabolite, MHD, which is primarily responsible for the pharmacological effect of TRILEPTAL. MHD is metabolized further by conjugation with glucuronic acid. Minor amounts (4% of the dose) are oxidized to the pharmacologically inactive 10,11-dihydroxy metabolite (DHD).

Oxcarbazepine is cleared from the body mostly in the form of metabolites which are predominantly excreted by the kidneys. More than 95% of the dose appears in the urine, with less than 1% as unc…

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide and Instructions for Use). Administration Information Counsel patients that TRILEPTAL may be taken with or without food. For TRILEPTAL oral suspension, advise patients to shake the bottle well and prepare the dose immediately afterwards using the oral dosing syringe supplied.

Inform patients that TRILEPTAL oral suspension can be mixed in a small glass of water just prior to administration or, alternatively, may be swallowed directly from the syringe. Instruct patients to discard any unused TRILEPTAL oral suspension after 7 weeks of first opening the bottle [ se e Dosage and Administration (2.8 ) and How Supplied/Storage and Handling (16) ] . Hyponatremia Advise patients that TRILEPTAL may reduce the serum sodium concentrations especially if they are taking other medications that can lower sodium.

Instruct patients to report symptoms of low sodium like nausea, tiredness, lack of energy, confusion, and more frequent or more severe seizures [ see Warnings and Precautions (5.1) ]. Anaphylactic Reactions and Angioedema Anaphylactic reactions and angioedema may occur during treatment with TRILEPTAL. Advise patients to report immediately signs and symptoms suggesting angioedema (swelling of the face, eyes, lips, tongue, or difficulty in swallowing or breathing) and to stop taking the drug until they have consulted with their physician [ see Warnings and Precautions (5.2) ].

Cross Hypersensitivity Reaction to Carbamazepine Inform patients who have exhibited hypersensitivity reactions to carbamazepine that approximately 25% to 30% of these patients may experience hypersensitivity reactions with TRILEPTAL. Patients should be advised that if they experience a hypersensitivity reaction while taking TRILEPTAL they should consult with their physician immediately [ see Warnings and Precautions (5.3) ]. Serious Dermatological Reactions Advise patients that serious skin reactions have been reported in association with TRILEPTAL.

In the event a skin reaction should occur while taking TRILEPTAL, patients should consult with their physician immediately [ see Warnings and Precautions (5.4) ]. Suicidal Behavior and Ideation Patients, their caregivers, and families should be counseled that AEDs, including TRILEPTAL, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of 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 (5.5)] . Driving and Operating Machinery Advise patients that TRILEPTAL may cause adverse reactions, such as dizziness, somnolence, ataxia, visual disturbances, and depressed level of consciousness.

This Medication Guide has been approved by the U.S. Food and Drug Administration Revised: 9/2025 MEDICATION GUIDE TRILEPTAL (try-LĔP-tăl) (oxcarbazepine) film-coated tablets, for oral use and oral suspension What is the most important information I should know about TRILEPTAL? Do not stop taking TRILEPTAL without first talking to your healthcare provider.

Stopping TRILEPTAL suddenly can cause serious problems. TRILEPTAL can cause serious side effects, including: 1. TRILEPTAL may cause the level of sodium in your blood to be low .

Symptoms of low blood sodium include: • nausea • confusion • tiredness (lack of energy) • more frequent or more severe seizures • headache Similar symptoms that are not related to low sodium may occur from taking TRILEPTAL. You should tell your healthcare provider if you have any of these side effects and if they bother you or they do not go away. Some other medicines can also cause low sodium in your blood.

Be sure to tell your healthcare provider about all the other medicines that you are taking. Your healthcare provider may do blood tests to check your sodium levels during your treatment with TRILEPTAL. 2.

TRILEPTAL may also cause allergic reactions or serious problems which may affect organs and other parts of your body like the liver or blood cells . You may or may not have a rash with these types of reactions. Call your healthcare provider right away if you have any of the following: • swelling of your face, eyes, lips, or tongue • painful sores in the mouth or around your eyes • trouble swallowing or breathing • yellowing of your skin or eyes • a skin rash • unusual brusing or bleeding • hives • severe fatigue or weakness • fever, swollen glands, or sore throat that do not go away or come and go • severe muscle pain • frequent infections or infections that do not go away Many people who are allergic to carbamazepine are also allergic to TRILEPTAL.

Tell your healthcare provider if you are allergic to carbamazepine. 3. Like other antiepileptic drugs (AEDs), TRILEPTAL 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 • trouble sleeping (insomnia) • attempts to commit suicide • new or worse irritability • new or worse depression • acting aggressive, being angry, or violent • new or worse anxiety • acting on dangerous impulses • feeling agitated or restless • an extreme increase in activity and talking (mania) • panic attacks • other unusual changes in behavior or mood 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.

Do not stop taking TRILEPTAL without first talking to a healthcare provider. Stopping TRILEPTAL suddenly can cause serious problems. Stopping a seizure medicine suddenly in a patient who has epilepsy may cause seizures that will not stop (status epilepticus).

Suicidal thoughts or actions may be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes. What is TRILEPTAL?

TRILEPTAL is a prescription medicine used: alone or with other medicines to treat partial-onset seizures in adults alone to treat partial-onset seizures in children 4 years of age and older with other medicines to treat partial-onset seizures in children 2 years of age and older It is not known if TRILEPTAL is safe and effective for use alone to treat partial-onset seizures in children less than 4 years of age or for use with other medicines to treat partial-onset seizures in children less than 2 years of age. Do not take TRILEPTAL if you are allergic to TRILEPTAL or a…
