📖 What it is MedlinePlus · NLM

Isotretinoin is used to treat severe recalcitrant nodular acne (a certain type of severe acne) that has not been helped by other treatments, such as antibiotics. Isotretinoin is in a class of medications called retinoids. It works by slowing the production of certain natural substances that can cause acne.

17 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 · Q2 2026 $4.13 $123.90 / 30 capsules
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.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Isotretinoin — the program that covers self-administered drugs. 7 manufacturers.
⚠️ 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 Isotretinoin. 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.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

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 69238-1255-3, 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: 69238-1255-03, written without dashes as 69238125503. 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 69238-1255-03, the first segment (69238) is the labeler code FDA assigned to Amneal Pharmaceuticals NY LLC; the middle segment (1255) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (03) 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 Amneal Pharmaceuticals NY LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Amneal Pharmaceuticals NY 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?

🚨 Boxed Warning ~1 min read

WARNING: EMBRYO-FETAL TOXICITY – CONTRAINDICATED IN PREGNANCY Isotretinoin can cause life-threatening birth defects and is contraindicated in pregnancy. There is an extremely high risk that life-threatening birth defects will result if pregnancy occurs while taking any amount of isotretinoin even for short periods of time. Potentially any fetus exposed during pregnancy can be affected.

There are no accurate means of determining prenatally whether an exposed fetus has been affected. If pregnancy occurs, discontinue isotretinoin immediately and refer the patient to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling [see Contraindications (4) , Warnings and Precautions (5.1) , and Use in Specific Populations (8.1) ] . Because of the risk of embryo-fetal toxicity, isotretinoin are available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the iPLEDGE REMS [see Warnings and Precautions (5.2) ] .

⏱️ Dosage and Administration ~3 min read

2 DOSAGE AND ADMINISTRATION Isotretinoin capsules are not substitutable with ABSORICA LD because of different bioavailability and recommended dosage. (2.1 , 5.3) Recommended dosage for: Isotretinoin capsules are 0.5 to 1 mg/kg/day given in two divided doses without regard to meals for 15 to 20 weeks (2.1) Adult patients with very severe disease (scarring, trunk involvement) may increase dosage to 2 mg/kg/day of isotretinoin capsules in divided doses. (2.1) Once daily dosing is not recommended.

(2.1) If a dose of isotretinoin capsules is missed, just skip that dose. Do not take two doses of isotretinoin capsules at the same time. (2.1) Perform pregnancy tests prior to prescribing, each month during therapy, end of therapy, and one month after discontinuation.

(2.3 , 8.3) Prior to prescribing, perform fasting lipid profile and liver function tests. (2.3)

2.1Recommended Dosage Isotretinoin capsules are not substitutable with ABSORICA LD [see Warnings and Precautions (5.3) ] . The recommended dosage of: Isotretinoin capsules are 0.5 to 1 mg/kg/day given in two divided doses with or without meals for 15 to 20 weeks (see Table 1). To decrease the risk of esophageal irritation, instruct patients to swallow the capsules with a full glass of liquid.

During treatment, the dosage may be adjusted according to response of the disease and/or adverse reactions, some of which may be dose-related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dosage adjustments up to 2 mg/kg/day for isotretinoin capsules in divided doses, as tolerated. The safety and effectiveness of once daily dosing with isotretinoin capsules has not been established and is not recommended.

If a dose of isotretinoin capsules are missed, just skip that dose. Do not take two doses of isotretinoin capsules at the same time.

2.2Duration of Use A normal course of treatment is 15 to 20 weeks. If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, may discontinue isotretinoin capsules. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, may initiate a second course of isotretinoin capsules in patients who have completed skeletal growth.

The use of another course of isotretinoin capsules therapy is not recommended before a two-month waiting period because the patient’s acne may continue to improve after a 15 to 20-week course of therapy. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of isotretinoin capsules, even in low dosages, has not been studied, and is not recommended.

The effect of long-term use of isotretinoin capsules on bone loss is unknown [see Warnings and Precautions (5.12) ] .

2.3Laboratory Testing Prior to Administration The following laboratory testing must be completed prior to isotretinoin capsules use: Pregnancy testing: Ensure patient is not pregnant prior to administering isotretinoin capsules [see Contraindications (4) and Use in Specific Populations (8.1 , 8.3) ] A fasting lipid profile including triglycerides [see Warnings and Precautions (5.8 , 5.15) ] . Liver function tests [see Warnings and Precautions (5.10 , 5.15) ] .

5 WARNINGS AND PRECAUTIONS Psychiatric Disorders (depression, psychosis, suicidal thoughts and behavior, and aggressive and/or violent behaviors): Prior to and during therapy assess for these conditions; stop if these conditions occur on therapy (5.4) Intracranial Hypertension (Pseudotumor Cerebri): Avoid use with concomitant tetracyclines (5.5) Serious Skin Reactions: Monitor for Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and other serious skin reactions (5.6) Acute Pancreatitis: If occurs, discontinue treatment (5.7) Lipid Abnormalities (hypertriglyceridemia, low HDL, and elevation of cholesterol): Monitor lipid levels at regular intervals; stop if hypertriglyceridemia cannot be controlled (5.8) Hearing Impairment: Discontinue and refer to specialized care (5.9) Hepatotoxicity: Monitor liver function tests prior to and during therapy (5.10 , 5.15) Inflammatory Bowel Disease: Discontinue for abdominal pain, rectal bleeding, or severe diarrhea (5.11) Musculoskeletal Abnormalities: Arthralgias, back pain, decreases in bone mineral density and premature epiphyseal closure (5.12) Ocular Abnormalities e.g., corneal opacities, decreased night vision: If visual symptoms occur, discontinue and refer for an ophthalmological exam (5.13)

5.1Embryo-Fetal Toxicity Isotretinoin is contraindicated in pregnancy [see Contraindications (4.1) ] . Based on human data, isotretinoin can cause fetal harm when administered to a pregnant patient. There is an extremely high risk that life-threatening birth defects will result if pregnancy occurs while taking any amount of isotretinoin even for short periods of time.

Potentially any fetus exposed during pregnancy can be affected. There are no accurate means of determining prenatally whether an exposed fetus has been affected. Major congenital malformations, spontaneous abortions, and premature births have been documented following exposure to isotretinoin during pregnancy [see Use in Specific Populations (8.1) ] .

If a pregnancy occurs during isotretinoin treatment, discontinue isotretinoin immediately and refer the patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure during or 1 month after isotretinoin therapy must be reported immediately to the FDA via the MedWatch telephone number 1-800-FDA-1088, and also to the iPLEDGE pregnancy registry at 1-866-495-0654 or via the internet ( www.ipledgeprogram.com ). Patients must be informed not to donate blood during isotretinoin therapy and for 1 month following discontinuation because the blood might be given to a pregnant patient whose fetus must not be exposed to isotretinoin.

Isotretinoin is available only through a restricted program under a REMS [see Warnings and Precautions (5.2) ] . 5.2 iPLEDGE Program Isotretinoin are available only through a restricted program under a REMS called the iPLEDGE REMS because of the risk of embryo-fetal toxicity [see Warnings and Precautions (5.1) ] . Notable requirements of the iPLEDGE REMS include the following: Prescribers must be certified with the program and comply with the following requirements: Determine reproductive status of all patients prior to initiating treatment Provide contraception counseling to patients who can get pregnant prior to and during treatment, or refer patients who can get pregnant to an expert for such counseling Provide scheduled pregnancy testing, and verify and document the negative pregnancy test result prior to writing each prescription, for no more than a 30-day supply Patients who can become pregnant must be enrolled by signing an informed consent form and must comply with the following requirements Comply with the pregnancy testing and contraception requirements [see Use in Specific Populations (8.3) ] Demonstrate comprehension of the safe-use conditions of the program every month Obtain the prescription within 7 days of the pregnancy test collection Patients who canno…

7 DRUG INTERACTIONS Vitamin A: may cause additive adverse reactions (7.1) Tetracyclines: avoid concomitant use (7.2)

7.1Vitamin A Isotretinoin is closely related to vitamin A. Therefore, the use of both vitamin A and isotretinoin at the same time may lead to vitamin A related adverse reactions. Patients treated with isotretinoin should be advised against taking supplements containing Vitamin A to avoid additive toxic effects.

7.2Tetracyclines Concomitant treatment with isotretinoin and tetracyclines should be avoided because isotretinoin use has been associated with a number of cases of intracranial hypertension (pseudotumor cerebri), some of which involved concomitant use of tetracyclines [see Warnings and Precautions (5.5) ] .

7.3Phenytoin Phenytoin is known to cause osteomalacia. No formal clinical trials have been conducted to assess if there is an interactive effect on bone loss between phenytoin and isotretinoin. Therefore, caution should be exercised when using these drugs together.

7.4Systemic Corticosteroids Systemic corticosteroids are known to cause osteoporosis. No formal clinical trials have been conducted to assess if there is an interactive effect on bone loss with concomitant use of systemic corticosteroids and isotretinoin. Therefore, caution should be exercised when using these drugs together.

7.5Norethindrone and Ethinyl Estradiol In a trial of 31 premenopausal female patients with severe recalcitrant nodular acne receiving norethindrone and ethinyl estradiol as an oral contraceptive agent, isotretinoin capsules within the recommended dosage, did not induce clinically relevant changes in the pharmacokinetics of ethinyl estradiol and norethindrone and in the serum levels of progesterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Although this study did not show any clinically significant interaction between isotretinoin and norethindrone, it is not known if there is an interaction between isotretinoin with other progestins.

8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding not recommended (8.2) .

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in patients exposed to isotretinoin during pregnancy. Report any suspected fetal exposure during or 1 month after isotretinoin therapy immediately to the FDA via the MedWatch telephone number 1-800-FDA-1088 and also to the iPLEDGE pregnancy registry at 1-866-495-0654 or via the internet ( www.ipledgeprogram.com ). Risk Summary Isotretinoin are contraindicated during pregnancy because isotretinoin can cause fetal harm when administered to a pregnant patient.

There is an increased risk of major congenital malformations, spontaneous abortions, and premature births following isotretinoin exposure during pregnancy in humans. If isotretinoin is used during pregnancy, or if the patient becomes pregnant while taking isotretinoin, the patient should be apprised of the potential hazard to a fetus. If pregnancy occurs during treatment of a patient who is taking isotretinoin, isotretinoin must be discontinued immediately and the patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.

Data Human Data Major congenital malformations that have been documented following isotretinoin exposure include malformations of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. External malformations include: skull; ear (including anotia, micropinna, small or absent external auditory canals); eye (including microphthalmia); facial dysmorphia and cleft palate. Internal abnormalities include: CNS (including cerebral and cerebellar malformations, hydrocephalus, microcephaly, cranial nerve deficit); cardiovascular; thymus gland; parathyroid hormone deficiency.

In some cases, death has occurred as a result of the malformations. Cases of IQ scores less than 85 with or without other abnormalities have been reported in children exposed in utero to isotretinoin. An increased risk of spontaneous abortion and premature births have been reported with isotretinoin exposure during pregnancy.

8.2Lactation Risk Summary There are no data on the presence of isotretinoin in either animal or human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions in nursing infants from isotretinoin, advise patients that breastfeeding is not recommended during treatment with isotretinoin, and for at least 8 days after the last dose of isotretinoin.

8.3Females and Males of Reproductive Potential All patients who can become pregnant must comply with the iPLEDGE program requirements [see Warnings and Precautions (5.2) ] . Pregnancy Testing Isotretinoin must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test. Patients who can become pregnant must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initial isotretinoin prescription (the interval between the two tests must be at least 19 days).

The first test (a screening test) is obtained by the prescriber when the decision is made to prescribe isotretinoin therapy. The second pregnancy test (a confirmation test) is performed after the patient has used 2 forms of contraception for 1 month and during the first 5 days of the menstrual period immediately preceding the beginning of isotretinoin therapy (for patients with regular menstrual cycles) or immediately preceding the beginning of isotretinoin therapy (for patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding).

A pregnancy test must be repeated each month, in a CLIA-certified laboratory prior to the patient receiving each prescription. A pregnancy test must also be completed at…

🧒 Pediatric Use ~3 min read

8.4Pediatric Use The safety and effectiveness of isotretinoin for the treatment of severe recalcitrant nodular acne have been established in pediatric subjects ages 12 to 17 years. Use of isotretinoin in this age group for this indication is supported by evidence from a clinical trial (Study 1) that compared the use of isotretinoin capsules to another isotretinoin capsule product in 397 pediatric subjects (12 to 17 years) [see Clinical Studies (14) ] and pharmacokinetic data in pediatric subjects [see Clinical Pharmacology (12.3) ] .

The safety and effectiveness of isotretinoin in pediatric patients less than 12 years of age have not been established. Adverse Reactions in Pediatric Subjects In trials with isotretinoin capsules, adverse reactions reported in pediatric subjects aged 12 to 17 years old were similar to those described in adults except for the increased incidence of back pain and arthralgia (both of which were sometimes severe) and myalgia in pediatric subjects. In a trial of pediatric subjects aged 12 to 17 years old treated with isotretinoin capsules, approximately 29% (104/358) developed back pain.

Back pain was severe in 14% (14/104) of the cases and occurred at a higher frequency in female subjects than male subjects. Arthralgias were experienced in 22% (79/358) of pediatric subjects including severe arthralgias in 8% (6/79) of subjects. Appropriate evaluation of the musculoskeletal system should be done in adolescents who present with these symptoms during or after a course of isotretinoin.

Consider discontinuing isotretinoin if any significant abnormality is found. Effects on Bone Mineral Density in Pediatric Subjects The effect on bone mineral density (BMD) of a 20-week course of therapy with isotretinoin capsules or another isotretinoin capsule product was evaluated in a double-blind, randomized clinical trial involving 396 adolescents with severe recalcitrant nodular acne (mean age 15.4 years old, range 12 to 17 years old, 80% males). Given that there were no statistically significant differences between the two isotretinoin capsule groups following 20 weeks of treatment, the results are presented for the pooled treatment groups.

The mean changes in BMD from baseline for the overall trial population were 1.8% for lumbar spine, -0.1% for total hip and -0.3% for femoral neck. Mean BMD Z-scores declined from baseline at each of these sites (-0.053, -0.109 and -0.104 respectively). Out of 306 adolescents, 27 (9%) had clinically significant BMD declines defined as ≥4% lumbar spine or total hip, or ≥5% femoral neck, including 2 subjects for lumbar spine, 17 for total hip and 20 for femoral neck.

Repeat DXA scans within 2 to 3 months after the post treatment scan showed no recovery of BMD. Long-term follow-up at 4 to 11 months showed that 3 out of 7 subjects had total hip and femoral neck BMD below pre-treatment baseline, and 2 others did not show the increase in BMD above baseline expected in this adolescent population. The significance of these changes in regard to long-term bone health and future fracture risk is unknown [see Warnings and Precautions (5.12) ] .

In an open-label clinical trial (N=217) of a single course of therapy with isotretinoin capsules for adolescents with severe recalcitrant nodular acne, BMD at several skeletal sites were not significantly decreased (lumbar spine change >-4% and total hip change >-5%) or were increased in the majority of subjects. One patient had a decrease in lumbar spine BMD >4% based on unadjusted data. Sixteen (8%) subjects had decreases in lumbar spine BMD >4%, and all the other subjects (92%) did not have significant decreases or had increases (adjusted for body mass index).

Nine subjects (5%) had a decrease in total hip BMD >5% based on unadjusted data. Twenty-one (11%) subjects had decreases in total hip BMD >5%, and all the other subjects (89%) did not have significant decreases or had increases (adjusted for body mass index). Follow-up trials performed in 8 o…

🧓 Geriatric Use 58 words

8.5Geriatric Use Clinical studies of isotretinoin did not include sufficient numbers of geriatric subjects (subjects aged 65 years of age and older) to determine whether they respond differently from younger adults. Although reported clinical experience has not identified differences in responses between geriatric and younger adults, effects of aging may increase some risks associated with isotretinoin therapy.

🆘 Overdosage 109 words

10 OVERDOSAGE In humans, isotretinoin overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolved without apparent residual effects. Patients who can become pregnant who present with an isotretinoin overdosage should be evaluated for pregnancy.

Because an overdosage would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients treated with isotretinoin should use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for 1 month after the overdose. All patients with isotretinoin overdose should not donate blood for at least 1 month.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Isotretinoin is a retinoid, which when administered at the recommended dosage [see Dosage and Administration (2.1) ] , inhibits sebaceous gland function and keratinization. Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with isotretinoin capsules and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.

The exact mechanism of action of isotretinoin in the treatment of severe recalcitrant nodular acne is unknown.

12.2Pharmacodynamics The pharmacodynamics of isotretinoin is unknown.

12.3Pharmacokinetics No clinically significant differences in the pharmacokinetics of isotretinoin between patients with nodular acne and healthy subjects without acne were reported in published literature. Absorption Following Isotretinoin Administration The isotretinoin mean T max was 6.4 hours under fed conditions and 2.9 hours under fasting conditions following administration of a single 40 mg dose. Effect on Food No clinically significant differences in isotretinoin pharmacokinetics were observed following administration with a modified high-fat, high-calorie meal (123.2 calories from protein, 265.6 calories from carbohydrates, and 468 calories from fat; total calories 857 calories) with reduced vitamin A content.

The mean AUC 0-t and C max of isotretinoin were 6095 ng*hr/mL and 369 ng/mL, respectively, following administration of a single 40 mg isotretinoin dose under fed conditions; which were approximately 50% and 26% higher, respectively, compared to fasting conditions. However, isotretinoin may be given with or without meals [see Dosage and Administration (2.1) ] . Distribution Isotretinoin is more than 99.9% bound to plasma proteins, primarily albumin.

Elimination The mean elimination half-lives of isotretinoin and its 4-oxo-isotretinoin metabolite were: 18 hours and 38 hours, respectively, after a single oral isotretinoin 40 mg dose. Metabolism: Isotretinoin is primarily metabolized by CYP2C8, 2C9, 3A4, and 2B6 in vitro . Isotretinoin and its metabolites are further metabolized into conjugates.

Following oral administration of isotretinoin capsules, at least three metabolites (4-oxo-isotretinoin, retinoic acid (tretinoin), and 4-oxo-retinoic acid (4-oxo-tretinoin)) have been identified in human plasma. The extent of formation of all metabolites was higher under fed conditions. All of these metabolites possess retinoid activity in vitro .

The clinical significance is unknown. Excretion: Following oral administration of an 80 mg dose of radiolabeled-isotretinoin as a liquid suspension, the metabolites of isotretinoin were excreted in feces and urine in relatively equal amounts (total of 65% to 83%). Specific Populations Pediatric Patients: No clinically significant differences in the pharmacokinetics of isotretinoin were observed based on age (12 to 15 years (n=38), and ≥18 years (n=19)).

In both age groups, 4- oxo -isotretinoin was the major metabolite; tretinoin and 4- oxo -tretinoin were also observed [see Use in Specific Populations (8.4) ] . Drug Interaction Studies No clinically significant differences in the pharmacokinetics of phenytoin (CYP2C9 substrate) were observed when used concomitantly with isotretinoin.
