📖 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.

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 00591-2436-15, 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.

📊 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.

For the detailed requirements prior to prescribing isotretinoin capsules, see Use in Specific Populations ( 8.3 ) . Prior to isotretinoin capsules use in all patients, complete the following laboratory testing: 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 )] .

2.2Recommended Dosage Isotretinoin capsules are not substitutable with ABSORICA LD [see Warnings and Precautions ( 5.3 )] . The recommended dosage of: Isotretinoin capsules is 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.

Swallow capsules whole. Do not split, crush, chew, or suck on the capsules. 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 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 have not been established and is not recommended. If a dose of isotretinoin capsules is missed, just skip that dose.

Do not take two doses of isotretinoin capsules at the same time.

2.3Recommended Duration 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 treatment, 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 treatment is not recommended before a 2-month waiting period because the patient’s acne may continue to improve after a 15 to 20-week course of treatment. 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.

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, immediately discontinue isotretinoin and refer the patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Immediately report any suspected fetal exposure during or 1 month after isotretinoin treatment 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). Inform patients not to donate blood during isotretinoin treatment 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 REMS 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 ( 5.1 )] . Notable requirements of the iPLEDGE REMS include the following: Prescribers must be certified in the REMS and comply with the REMS requirements, including the following: Assess the reproductive status of all patients prior to initiating treatment and during treatment.

Counsel patients who cannot get pregnant on the risk and REMS requirements prior to initiating treatment. Counsel patients who can get pregnant on the risk and REMS requirements prior to and during treatment. Counsel patients who can get pregnant on pregnancy prevention requirements prior to and during treatment, or refer patients who can get pregnant to an expert for such counseling.

Comply with the pregnancy testing requirements. Assess the pregnancy status for patients who can get pregnant by reviewing pregnancy tests and documenting a negative result prior to each prescriptio…

7 DRUG INTERACTIONS Vitamin A : avoid concomitant use ( 7.1 ) Tetracyclines : avoid concomitant use ( 7.2 )

7.1Vitamin A Avoid concomitant use of isotretinoin with supplements containing vitamin A. Isotretinoin is closely related to vitamin A. Therefore, concomitant use of isotretinoin with vitamin A may lead to isotretinoin-associated adverse reactions.

7.2Tetracyclines Avoid concomitant use of isotretinoin with tetracyclines 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 )] .

7.3Oral Contraceptives Isotretinoin Capsules did not result in clinically significant changes in the pharmacokinetics of norethindrone and ethinyl estradiol when used concomitantly with a norethindrone and ethinyl estradiol oral contraceptive [see Clinical Pharmacology ( 12.3 )] . It is not known if there is an interaction with the concomitant use of isotretinoin with other oral contraceptives.

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Lactation : Breastfeeding not recommended ( 8.2 ). In Patients Who Can Get Pregnant : Pregnancy testing is required prior to, during, and after isotretinoin capsules treatment. See the Full Prescribing Information for the detailed pregnancy test and contraception requirements. ( 8.3 ).

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that documents pregnancies in patients exposed to isotretinoin during pregnancy. Report any suspected fetal exposure during or 1 month after isotretinoin treatment 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 is 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, apprise the patient of the potential hazard to a fetus. If pregnancy occurs during treatment of a patient who is taking isotretinoin, immediately discontinue isotretinoin and refer the patient 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: central nervous system (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 get pregnant must comply with the iPLEDGE REMS requirements [see Warnings and Precautions ( 5.2 )] . Pregnancy Testing In patients who can get pregnant, pregnancy testing is required prior to, during, and after isotretinoin treatment. Pregnancy Testing Prior to Prescribing Isotretinoin: In patients who can get pregnant, only prescribe isotretinoin after verification and documentation that they are not pregnant: (1) Complete the first urine or serum pregnancy test (screening test) in a medical setting (e.g., prescriber’s office, clinic, laboratory) and verify and document that the test is negative, AND (2) For patients with: Regular menstrual cycles, complete the second urine or serum pregnancy test (confirmatory test) in a medical setting (1) at least 30 days after the screening test and during the first five days of their menstrual period immediately preceding the beginning of isotretinoin treatment, AND (2) after the patient has used their chosen pregnancy prevention methods (i.e., two forms of contraception or committed to abstinence) for at least 30 days…

🧒 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 non-pregnant pediatric patients 12 years of age and older with multiple inflammatory nodules with a diameter of 5 mm or greater who are unresponsive to conventional therapy, including systemic antibiotics. Use of isotretinoin in this age group for this indication is supported by evidence from a clinical trial (Study 1) that compared the use isotretinoin capsules to another isotretinoin capsule product in 397 pediatric subjects 12 years of age and older [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 12 years of age and older 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 12 years of age and older 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. Evaluate the musculoskeletal system of pediatric patients 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 treatment with isotretinoin or another isotretinoin capsule product was evaluated in a double-blind, randomized clinical trial involving 396 pediatric subjects 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 pediatric subjects, 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 treatment with isotretinoin capsules for pediatric subjects 12 years of age and older 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 subject 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%)…

🧓 Geriatric Use 45 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 adult subjects. The effects of aging may increase some risks associated with isotretinoin treatment.

🆘 Overdosage 127 words

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

Because an overdosage would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, instruct male patients treated with isotretinoin to use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for 1 month after the overdose. Instruct all patients with isotretinoin overdose to not donate blood for at least 1 month. If an overdose occurs, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The exact mechanism of action of isotretinoin in the treatment of severe recalcitrant nodular acne in non-pregnant patients 12 years of age and older with multiple inflammatory nodules with a diameter of 5 mm or greater who are unresponsive to conventional therapy, including systemic antibiotics is unknown. Isotretinoin is a retinoid, which 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 reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.

12.2Pharmacodynamics Decreased sebum secretion is related to the dose and duration of treatment with isotretinoin.

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 Phenytoin: No clinically significant differences in the pharmacokinetics of phenytoin (CYP2C9 substrate) were observed when used concomitantly with isotretinoin. Norethindrone and Ethinyl Estradiol: There were no clinically significant differences in the pharmacokinetics of norethindrone and ethinyl estradiol after the concomitant use of isotretinoin capsules 1 mg/kg/day with an oral contraceptive in premenopausal female patients with severe recalcitrant nodular acne.

Additionally, there were no clinically significant differences in the serum levels of progesterone, follicle-stimulating hormone and luteinizing hormone in the serum levels of proges…
