11 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 DailyMedingredient 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.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
ℹ️
No price is published for this exact package yet. CMS surveys NADAC per package size, so a different pack of the same drug often has one.
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.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 52427-821-30, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 52427-0821-30, written without dashes as 52427082130. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 52427-0821-30, the first segment (52427) is the labeler code FDA assigned to Almatica Pharma LLC; the middle segment (0821) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (30) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Almatica Pharma LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Almatica Pharma LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?

( 5.2 ) Orthostatic Hypotension, Falls and Syncope : Consider dosage reduction or discontinuation if these events occur. ( 5.3 ) Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents but also when taken alone. If it occurs, discontinue Duloxetine Delayed-Release Capsules and serotonergic agents.

( 5.4 ) Increased Risk of Bleeding : May increase the risk of bleeding events. Concomitant use of antiplatelet drugs and anticoagulants may increase this risk. ( 5.5 , 7 , 8.1 ) Severe Skin Reactions: Severe skin reactions, including erythema multiforme and Stevens-Johnson Syndrome (SJS), can occur.

Discontinue at the first appearance of blisters, peeling rash, mucosal erosions, or any other sign of hypersensitivity if no other etiology can be identified. ( 5.6 ) Discontinuation Syndrome : Taper dose when possible and monitor for discontinuation symptoms. ( 5.7 ) Activation of Mania or Hypomania : Prior to initiating, screen patients for personal or family history of bipolar disorder, mania, or hypomania.

5.1Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in the antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied.

There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1. Table 1: Risk Differences of the Number of Patients of Suicidal Thoughts and Behavior in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range Drug-Placebo Difference in Number of Patients of Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo <18 14 additional patients 18 to 24 5 additional patients Decreases Compared to Placebo 25 to 64 1 fewer patient ≥65 6 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months.

However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors. Monitor all antidepressant-treated patients for any indication for clinical worsening and emergence of…

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. The safety of Duloxetine Delayed-Release Capsules for the treatment for major depressive disorder (MDD) in adults and for the treatment of generalized anxiety disorder (GAD) in adults and pediatric patients is based upon adequate and well-controlled studies of another duloxetine delayed-release capsule product.

The results of these adequate and well-controlled studies of duloxetine delayed-release capsules are presented below. The stated frequencies of adverse reactions represent the proportion of patients who experienced, at least once, one treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation.

Adverse Reactions in Adults Adult Clinical Trial Database The data described below reflect exposure to duloxetine delayed-release capsules in placebo-controlled trials for MDD (N=3779), GAD (N=1018), and other indications (N=3303). The population studied was 17 years to 89 years of age. 66% and 61% were female, and 82% and 73% were Caucasian in the MDD and GAD populations, respectively.

Most patients received duloxetine delayed-release capsules dosages of a total of 60 mg to 120 mg per day [see Clinical Studies ( 14.1 , 14.2 )] . The data below do not include results of the trial examining the efficacy of duloxetine delayed-release capsules in patients ≥ 65 years old for the treatment of generalized anxiety disorder; however, the adverse reactions observed in this geriatric sample were generally similar to adverse reactions in the overall adult population. Adverse Reactions Reported as Reasons for Discontinuation of Treatment in Adult Placebo-Controlled Trials Major Depressive Disorder Approximately 8.4% (319/3779) of the duloxetine delayed-release capsules-treated patients in placebo-controlled adult trials for MDD discontinued treatment due to an adverse reaction, compared with 4.6% (117/2536) of placebo-treated patients.

Nausea (duloxetine delayed-release capsules 1.1%, placebo 0.4%) was the only adverse reaction reported as a reason for discontinuation and considered to be drug-related (i.e., discontinuation occurring in at least 1% of the…

8 USE IN SPECIFIC POPULATIONS Pregnancy : Third trimester use may increase risk for symptoms of poor adaptation (respiratory distress, temperature instability, feeding difficulty, hypotonia, tremor, irritability) in the neonate. ( 8.1 ) Hepatic Impairment : Avoid use in patients with chronic liver disease or cirrhosis. ( 8.6 ) Renal Impairment : Avoid use in patients with severe renal impairment, GFR <30 mL/minute. ( 8.7 )

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors the pregnancy outcomes in women exposed to antidepressants, including Duloxetine Delayed-Release Capsules, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/antidepressants. Risk Summary Data from a postmarketing retrospective cohort study indicate that use of duloxetine in the month before delivery may be associated with an increased risk of postpartum hemorrhage.

Data from published literature and from a postmarketing retrospective cohort study have not identified a clear drug-associated risk of major birth defects or other adverse developmental outcomes (see Data) . There are risks associated with untreated depression in pregnancy, and with exposure to SNRIs and SSRIs, including Duloxetine Delayed-Release Capsules, during pregnancy (see Clinical Considerations). In rats and rabbits treated with duloxetine during the period of organogenesis, fetal weights were decreased but there was no evidence of developmental effects at doses up to 3 times and 6 times, respectively, the maximum recommended human dose (MRHD) of 120 mg/day given to adolescents on a mg/m 2 basis.

When duloxetine was administered orally to pregnant rats throughout gestation and lactation, pup weights at birth and pup survival to 1 day postpartum were decreased at a dose 2 times the MRHD given to adolescents on a mg/m 2 basis. At this dose, pup behaviors consistent with increased reactivity, such as increased startle response to noise and decreased habituation of locomotor activity were observed. Post-weaning growth was not adversely affected.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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.

Clinical Considerations Disease-associated Maternal and/or Embryo/Fetal Risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. This finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

Maternal Adverse Reactions Use of Duloxetine Delayed-Release Capsules in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions ( 5.5 )]. Fetal/Neonatal Adverse Reaction Neonates exposed to duloxetine and other SNRIs or SSRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery.

Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These findings are consistent with either a direct tox…

🧒 Pediatric Use ~2 min read

8.4Pediatric Use Antidepressants increased the risk of suicidal thoughts and behavior in pediatric patients. Monitor all pediatric patients being treated with antidepressants for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of treatment, or at times of dosage changes [see Warnings and Precautions ( 5.1 )] . Perform regular monitoring of weight and growth in pediatric patients treated with Duloxetine Delayed-Release Capsules [see Adverse Reactions ( 6.1 )] .

Generalized Anxiety Disorder The safety and effectiveness of Duloxetine Delayed-Release Capsules for the treatment of generalized anxiety disorder (GAD) in patients 7 years to 17 years of age is based upon an adequate and well‑controlled study of another duloxetine delayed-release capsule product. Use of Duloxetine Delayed-Release Capsules for this indication is supported by evidence from a single 10-week, placebo-controlled trial (Study 6) in 272 patients aged 7 to 17 years with GAD. Duloxetine delayed-release capsules demonstrated superiority over placebo as measured by greater improvement in the Pediatric Anxiety Rating Scale (PARS) for GAD severity score [see Clinical Studies ( 14.2 )].

The safety and effectiveness of Duloxetine Delayed-Release Capsules for the treatment of GAD have not been established in pediatric patients less than 7 years of age. Major Depressive Disorder The safety and effectiveness of Duloxetine Delayed-Release Capsules have not been established in pediatric patients for the treatment of MDD. Effectiveness was not demonstrated in two adequate and well controlled trials conducted in 800 pediatric patients aged 7 years to 17 years with MDD.

Neither duloxetine delayed-release capsules nor an active control approved for treatment of pediatric MDD were superior to placebo in the 10-week trials. The most frequently observed adverse reactions in the MDD pediatric clinical trials included nausea, headache, decreased weight, and abdominal pain. Decreased appetite and weight loss have been observed in association with the use of SSRIs and SNRIs.

Juvenile Animal Toxicology Data Duloxetine administration to young rats from post-natal day 21 (weaning) through post-natal day 90 (adult) resulted in decreased body weights that persisted into adulthood, but recovered when drug treatment was discontinued; slightly delayed (~1.5 days) sexual maturation in females, without any effect on fertility; and a delay in learning a complex task in adulthood, which was not observed after drug treatment was discontinued. These effects were observed at the high dose of 45 mg/kg/day (2 times the MRHD, for a child); the no-effect-level was 20 mg/kg/day (≈1 times the MRHD, for a child).

🧓 Geriatric Use ~2 min read

8.5Geriatric Use Geriatric Exposure in Premarketing Clinical Trials of Duloxetine Of the 2,418 patients in MDD trials, 6% (143) were 65 years of age or over. In the MDD and GAD studies, no overall differences in safety or effectiveness were generally observed between these patients and younger adult patients, and other reported clinical experience has not identified differences in responses between these geriatric and younger adult patients, but greater sensitivity of some older patients cannot be ruled out. SSRIs and SNRIs, including Duloxetine Delayed-Release Capsules, have been associated with clinically significant hyponatremia in geriatric patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions ( 5.12 )] .

In an analysis of data from all placebo-controlled trials, patients treated with duloxetine reported a higher rate of falls compared to placebo-treated patients. The increased risk appears to be proportional to a patient’s underlying risk for falls. Underlying risk appears to increase steadily with age.

As geriatric patients tend to have a higher prevalence of risk factors for falls such as medications, medical comorbidities and gait disturbances, the impact of increasing age by itself on falls during duloxetine treatment is unclear. Falls with serious consequences including bone fractures and hospitalizations have been reported with duloxetine use [see Warnings and Precautions ( 5.3 ), Adverse Reactions ( 6.1 )] . The pharmacokinetics of duloxetine after a single dose of 40 mg were compared in healthy elderly females (65 years to 77 years) and healthy middle-age females (32 years to 50 years).

There was no difference in the C max , but the area under the concentration-time curve (AUC) of duloxetine was somewhat (about 25%) higher and the half-life about 4 hours longer in the elderly females. Population pharmacokinetic analyses suggest that the typical values for clearance decrease by approximately 1% for each year of age between 25 years to 75 years of age; but age as a predictive factor only accounts for a small percentage of between-patient variability. Dosage adjustment based on the age of the adult patient is not necessary.

🆘 Overdosage ~1 min read

10 OVERDOSAGE

10.1Signs and Symptoms In postmarketing experience, fatal outcomes have been reported for acute duloxetine overdoses, primarily with mixed overdoses, but also with duloxetine only, including 1000 mg of duloxetine (approximately 8.3 times the maximum recommended dosage). Signs and symptoms of overdose (duloxetine alone or with mixed drugs) included somnolence, coma, serotonin syndrome, seizures, syncope, tachycardia, hypotension, hypertension, and vomiting.

10.2Management of Overdose There is no specific antidote to a duloxetine overdosage, but if serotonin syndrome ensues, specific treatment (such as with cyproheptadine and/or temperature control) may be considered. In case of acute overdose with Duloxetine Delayed-Release Capsules, treatment should consist of those general measures employed in the management of overdose with any drug, such as assuring an adequate airway, oxygenation, and ventilation and monitoring cardiac rhythm and vital signs. Gastric lavage with a large-bore orogastric tube with appropriate airway protection, if needed, may be indicated if performed soon after ingestion or in symptomatic patients.

Induction of emesis is not recommended. Activated charcoal may be useful in limiting absorption of duloxetine from the gastrointestinal tract. Administration of activated charcoal has been shown to decrease duloxetine AUC and C max by an average of one-third, although some patients had a limited effect of activated charcoal.

Due to the large volume of distribution of duloxetine, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be beneficial. In managing overdose, the possibility of multiple drug involvement should be considered. A specific caution involves patients who overdose with Duloxetine Delayed-Release Capsules and tricyclic antidepressants.

In such a case, decreased clearance of the parent tricyclic and/or its active metabolite may increase the possibility of clinically significant sequelae and extend the time needed for close medical observation [see Warnings and Precautions ( 5.4 ), Drug Interactions ( 7 )] . Consider contacting a Poison Help line (1-800-222-1222 or www.poison.org) for additional information on the treatment of overdosage.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Although the exact mechanisms of the antidepressant, central pain inhibitory and anxiolytic actions of duloxetine in humans are unknown, these actions are believed to be related to its potentiation of serotonergic and noradrenergic activity in the CNS.

12.2Pharmacodynamics Preclinical studies have shown that duloxetine is a potent inhibitor of neuronal serotonin and norepinephrine reuptake and a less potent inhibitor of dopamine reuptake. Duloxetine has no significant affinity for dopaminergic, adrenergic, cholinergic, histaminergic, opioid, glutamate, and GABA receptors in vitro . Duloxetine does not inhibit monoamine oxidase (MAO).

Duloxetine is in a class of drugs known to affect urethral resistance [see Warnings and Precautions ( 5.14 )] . Cardiac Electrophysiology The effect of duloxetine 160 mg and 200 mg administered twice daily (2.7 times and 3.3 times the maximum recommended dosage, respectively) to steady state was evaluated in a randomized, double-blinded, two-way crossover study in 117 healthy female adult subjects. No QT interval prolongation was detected.

Duloxetine appears to be associated with concentration-dependent but not clinically meaningful QT shortening. Alcohol When duloxetine and ethanol were administered several hours apart so that peak concentrations of each would coincide, duloxetine did not increase the impairment of mental and motor skills caused by alcohol.

12.3Pharmacokinetics No clinically significant difference in duloxetine exposure was observed following oral administration of either duloxetine delayed-release capsules or Duloxetine Delayed-Release Capsules. Duloxetine pharmacokinetics are dose proportional over the therapeutic range. Steady-state plasma concentrations are typically achieved after 3 days of dosing.

Absorption After oral duloxetine delayed-release capsules administration, the median lag time of absorption (T lag ) is 2 hours and maximal plasma concentrations (C max ) of duloxetine occurs at 6 hours post dose. There is a 3-hour delay in absorption and a one-third increase in apparent clearance of duloxetine after an evening dose as compared to a morning dose. Effect of Food Food delays the median time to reach peak concentration from 6 to 8 hours.

Administration of Duloxetine Delayed-Release Capsules to healthy subjects with a high-fat meal (containing 1000 calories, 50% fat) increased C max and area under the plasma concentration-time curve (AUC inf ) by 29% and 35%, respectively, compared to the fasted state. Distribution The apparent volume of distribution averages about 1640 L. Duloxetine is highly bound (>90%) to proteins in human plasma, binding primarily to albumin and α 1 -acid glycoprotein.

The interaction between duloxetine and other highly protein bound drugs has not been fully evaluated. Plasma protein binding of duloxetine is not affected by renal or hepatic impairment. Elimination Duloxetine has an elimination half-life of about 12 hours (range 8 hours to 17 hours).

Elimination of duloxetine is mainly through hepatic metabolism involving two P450 isozymes, CYP1A2 and CYP2D6. Metabolism Biotransformation and disposition of duloxetine in humans have been determined following oral administration of 14 C-labeled duloxetine. Duloxetine comprises about 3% of the total radiolabeled material in the plasma, indicating that it undergoes extensive metabolism to numerous metabolites.

The major biotransformation pathways for duloxetine involve oxidation of the naphthyl ring followed by conjugation and further oxidation. Both CYP1A2 and CYP2D6 catalyze the oxidation of the naphthyl ring in vitro . Metabolites found in plasma include 4-hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate.

Excretion Many additional metabolites have been identified in urine, some representing only minor pathways of elimination. Only trace (less than 1% of the dose) amounts of unchanged duloxetine are present in the urine. M…
