Version May 2024
Acitretin must not be used by females who are pregnant, or who intend to become pregnant during therapy or at any time for at least 3 years following discontinuation of therapy. Acitretin also must not be used by females who may not use reliable contraception while undergoing treatment and for at least 3 years following discontinuation of treatment. Acitretin is a metabolite of etretinate, and major human fetal abnormalities have been reported with the administration of acitretin and etretinate. Potentially, any fetus exposed can be affected.
Clinical evidence has shown that concurrent ingestion of acitretin and ethanol has been associated with the formation of etretinate, which has a significantly longer elimination half-life than acitretin. Because the longer elimination half-life of etretinate would increase the duration of teratogenic potential for female patients, ethanol must not be ingested by female patients of childbearing potential either during treatment with acitretin or for 2 months after cessation of therapy. This allows for elimination of acitretin, thus removing the substrate for transesterification to etretinate. The mechanism of the metabolic process for conversion of acitretin to etretinate has not been fully defined. It is not known whether substances other than ethanol are associated with transesterification.
Acitretin has been shown to be embryotoxic and/or teratogenic in rabbits, mice, and rats at doses of 0.6, 3, and 15 mg/kg, respectively. These doses are approximately 0.2, 0.3, and 3 times the maximum recommended therapeutic dose, respectively, based on a mg/m2 comparison.
Major human fetal abnormalities associated with acitretin and/or etretinate administration have been reported, including meningomyelocele, meningoencephalocele, multiple synostoses, facial dysmorphia, syndactyly, absence of terminal phalanges, malformations of hip, ankle and forearm, low-set ears, high palate, decreased cranial volume, cardiovascular malformation, and alterations of the skull and cervical vertebrae.
Acitretin should be prescribed only by those who have special competence in the diagnosis and treatment of severe psoriasis, are experienced in the use of systemic retinoids, and understand the risk of teratogenicity.
Because of the teratogenicity of acitretin, manufacturer-specific programs have been developed to educate women of childbearing potential and their health care providers about the serious risks associated with acitretin and to help prevent pregnancies from occurring with the use of this drug and for 3 years after its discontinuation.

Acitretin should be considered only for women with severe psoriasis unresponsive to other therapies or whose clinical condition contraindicates the use of other treatments.
Females of reproductive potential must not be given a prescription for acitretin until pregnancy is excluded. Acitretin is contraindicated in females of reproductive potential unless the patient meets all of the following conditions:
Must have had 2 negative urine or serum pregnancy tests with a sensitivity of at least 25 milliunits/mL before receiving the initial acitretin prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue acitretin therapy. The second pregnancy test (a confirmation test) should be done during the first 5 days of the menstrual period immediately preceding the beginning of acitretin therapy. For patients with amenorrhea, the second test should be done at least 11 days after the last act of unprotected sexual intercourse (without using 2 effective forms of contraception [birth control] simultaneously). If the second pregnancy test is negative, initiation of treatment should begin within 7 days of the specimen collection. Acitretin should be limited to a monthly supply.
Must have a pregnancy test with a sensitivity of at least 25 milliunits/mL repeated every month during treatment with acitretin. The patient must have a negative result from a urine or serum pregnancy test before receiving a prescription for acitretin. To encourage compliance with this recommendation, a monthly supply of the drug should be prescribed. For at least 3 years after discontinuing therapy, a pregnancy test must be repeated every 3 months.
Must have selected and have committed to use 2 effective forms of contraception (birth control) simultaneously, at least 1 of which must be a primary form, unless absolute abstinence is the chosen method, or the patient has undergone a hysterectomy or is clearly postmenopausal.
Patients must use 2 effective forms of contraception (birth control) simultaneously for at least 1 month prior to initiation of acitretin therapy, during acitretin therapy, and for at least 3 years after discontinuing acitretin therapy. Counseling about contraception and behaviors associated with an increased risk of pregnancy must be repeated on a monthly basis by the prescriber during acitretin therapy and every 3 months for at least 3 years following discontinuation of acitretin. Effective forms of contraception include both primary and secondary forms of contraception. Primary forms of contraception include the following: tubal ligation, partner's vasectomy, intrauterine devices, birth control pills, and injectable/implantable/insertable/topical hormonal birth control products. Secondary forms of contraception include condoms (with or without spermicide), diaphragms, and cervical caps (which must be used with a spermicide) and vaginal sponges (contains spermicide). Any birth control method can fail. Therefore, it is critically important that women of childbearing potential use 2 effective forms of contraception (birth control) simultaneously. It has not been established if there is a pharmacokinetic interaction between acitretin and combined oral contraceptives. However, it has been established that acitretin interferes with the contraceptive effect of microdosed progestin preparations. Microdosed “minipill” progestin preparations are not recommended for use with acitretin. It is not known whether other progestin-only contraceptives, such as implants and injectables, are adequate methods of contraception during acitretin therapy. Prescribers are advised to consult the package insert of any medication administered concomitantly with hormonal contraceptives because some medications may decrease the effectiveness of these birth control products. Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John's wort because a possible interaction has been suggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John's wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John's wort.
Must have signed a Patient Agreement/Informed Consent for Female Patients that contains warnings about the risk of potential birth defects if the fetus is exposed to acitretin, about contraceptive failure, and about the fact that they must not ingest beverages or products containing ethanol while taking acitretin and for 2 months after acitretin treatment has been discontinued, and about preventing pregnancy while taking acitretin and for at least 3 years after discontinuing treatment.
If pregnancy does occur during acitretin therapy or at any time for at least 3 years following discontinuation of acitretin therapy, the prescriber and patient should discuss the possible effects on the pregnancy. The available information is as follows:
Acitretin, the active metabolite of etretinate, is teratogenic and is contraindicated during pregnancy. The risk of severe fetal malformations is well established when systemic retinoids are taken during pregnancy. Pregnancy must also be prevented after stopping acitretin therapy, while the drug is being eliminated to below a threshold blood concentration that would be associated with an increased incidence of birth defects. Because this threshold has not been established for acitretin in humans and because elimination rates vary among patients, the duration of posttherapy contraception to achieve adequate elimination cannot be calculated precisely. It is strongly recommended that contraception be continued for at least 3 years after stopping treatment with acitretin, based on the following considerations:
In the absence of transesterification to form etretinate, greater than 98% of the acitretin would be eliminated within 2 months, assuming a mean elimination half-life of 49 hours.
In cases where etretinate is formed, as has been demonstrated with concomitant administration of acitretin and ethanol, greater than 98% of the etretinate formed would be eliminated in 2 years, assuming a mean elimination half-life of 120 days, and greater than 98% of the etretinate formed would be eliminated in 3 years, based on the longest demonstrated elimination half-life of 168 days. However, etretinate was found in plasma and subcutaneous fat in 1 patient reported to have had sporadic alcohol intake, 52 months after she stopped acitretin therapy.
Severe birth defects have been reported where conception occurred during the time interval when the patient was being treated with acitretin and/or etretinate. In addition, severe birth defects have also been reported when conception occurred after the mother completed therapy. These cases have been reported both prospectively (before the outcome was known) and retrospectively (after the outcome was known). The events below are listed without distinction as to whether the reported birth defects are consistent with retinoid-induced embryopathy or not.
There have been 318 prospectively reported cases involving pregnancies and the use of etretinate, acitretin, or both. In 238 of these cases, the conception occurred after the last dose of etretinate (103 cases), acitretin (126), or both (9). Fetal outcome remained unknown in approximately one-half of these cases, of which 62 were terminated and 14 were spontaneous abortions. Fetal outcome is known for the other 118 cases and 15 of the outcomes were abnormal (including cases of absent hand/wrist, clubfoot, GI malformation, hypocalcemia, hypotonia, limb malformation, neonatal apnea/anemia, neonatal ichthyosis, placental disorder/death, undescended testicle, and 5 cases of premature birth). In the 126 prospectively reported cases where conception occurred after the last dose of acitretin only, 43 cases involved conception at least 1 year but less than 2 years after the last dose. There were 3 reports of abnormal outcomes out of these 43 cases (involving limb malformation, GI tract malformations, and premature birth). There were only 4 cases where conception occurred at least 2 years after the last dose but there were no reports of birth defects in these cases.
There is also a total of 35 retrospectively reported cases where conception occurred at least 1 year after the last dose of etretinate, acitretin, or both. From these cases, there are 3 reports of birth defects when the conception occurred at least 1 year but less than 2 years after the last dose of acitretin (including heart malformations, Turner syndrome, and unspecified congenital malformations) and 4 reports of birth defects when conception occurred 2 or more years after the last dose of acitretin (including foot malformation, cardiac malformations [2 cases], and unspecified neonatal and infancy disorder). There were 3 additional abnormal outcomes in cases where conception occurred 2 or more years after the last dose of etretinate (including chromosome disorder, forearm aplasia, and stillbirth).
Females who have taken etretinate must continue to follow the contraceptive recommendations for etretinate. Etretinate is no longer marketed in the United States. For information, call the manufacturer:

Patients should not donate blood during and for at least 3 years following the completion of acitretin therapy because women of childbearing potential must not receive blood from patients being treated with acitretin.
Patients should not donate blood during and for at least 3 years following acitretin therapy because women of childbearing potential must not receive blood from patients being treated with acitretin.
Samples of seminal fluid from 3 male patients treated with acitretin and 6 male patients treated with etretinate have been assayed for the presence of acitretin. The maximum concentration of acitretin observed in the seminal fluid of these men was 12.5 ng/mL. Assuming an ejaculate volume of 10 mL, the amount of drug transferred in semen would be 125 ng, which is 1/200,000 of a single 25 mg capsule. Thus, although it appears that residual acitretin in seminal fluid poses little, if any, risk to a fetus while a male patient is taking the drug or after it is discontinued, the no-effect limit for teratogenicity is unknown and there is no registry for birth defects associated with acitretin. The available data are as follows:
There have been 25 cases of reported conception when the male partner was taking acitretin. The pregnancy outcome is known in 13 of these 25 cases. Of these, 9 reports were retrospective and 4 were prospective (meaning the pregnancy was reported prior to knowledge of the outcome).
When acitretin treatment was given at time of conception, there were 5 deliveries of healthy neonates (4 of 5 cases were prospective), 5 spontaneous abortions, and 1 induced abortion.
When acitretin was discontinued approximately 4 weeks prior to conception, there was 1 induced abortion (with malformation pattern not typical of retinoid embryopathy [bilateral cystic hygromas of neck, hypoplasia of lungs bilateral, pulmonary atresia, ventricular septal defect with overriding truncus arteriosus]).
When acitretin was discontinued approximately 6 to 8 months prior to conception, there was 1 spontaneous abortion.
An acitretin Medication Guide must be given to the patient each time acitretin is dispensed, as required by law.
Of the 525 patients treated in US clinical trials, 2 had clinical jaundice with elevated serum bilirubin and transaminases considered related to acitretin treatment. Liver function test results in these patients returned to normal after acitretin was discontinued. Two of the 1,289 patients treated in European clinical trials developed biopsy-confirmed toxic hepatitis. A second biopsy in 1 of these patients revealed nodule formation suggestive of cirrhosis. One patient in a Canadian clinical trial of 63 patients developed a 3-fold increase of transaminases. A liver biopsy of this patient showed mild lobular disarray, multifocal hepatocyte loss, and mild triaditis of the portal tracts compatible with acute reversible hepatic injury. The patient's transaminase levels returned to normal 2 months after acitretin was discontinued.
The potential of acitretin therapy to induce hepatotoxicity was prospectively evaluated using liver biopsies in an open-label study of 128 patients. Pretreatment and posttreatment biopsies were available for 87 patients. A comparison of liver biopsy findings before and after therapy revealed 58% of patients showed no change, 25% improved, and 17% of patients had a worsening of their liver biopsy status. For 6 patients, the classification changed from class 0 (no pathology) to class I (normal fatty infiltration; nuclear variability and portal inflammation; both mild); for 7 patients, the change was from class I to class II (fatty infiltration, nuclear variability, portal inflammation and focal necrosis; all moderate to severe); and for 1 patient, the change was from class II to class IIIb (fibrosis, moderate to severe). No correlation could be found between liver function test result abnormalities and the change in liver biopsy status, and no cumulative dose relationship was found.
Elevations of AST, ALT, gamma-glutamyl transpeptidase (GGT; GGTP), or lactate dehydrogenase (LDH) have occurred in approximately 1 in 3 patients treated with acitretin. Of the 525 patients treated in clinical trials in the United States, treatment was discontinued in 3.8% of patients due to elevated liver function test results. If hepatotoxicity is suspected during treatment with acitretin, the drug should be discontinued and the etiology further investigated.
Ten of 652 patients treated in US clinical trials of etretinate, of which acitretin is the active metabolite, had clinical or histologic hepatitis considered to be possibly or probably related to etretinate treatment. There have been reports of hepatitis-related deaths worldwide; a few of these patients had received etretinate for 1 month or less before presenting with hepatic symptoms or signs.

Acitretin is contraindicated in females of childbearing potential unless all of the following conditions apply.
1) Patient has severe psoriasis unresponsive to other therapy or if clinical condition contraindicates other treatments.
2) Patient must have two negative urine or serum pregnancy tests prior to therapy.
3) Patient must have pregnancy test repeated monthly during therapy. After discontinuation of therapy, a pregnancy test must be repeated every 3 months for at least 3 years.
4) Patient must commit to using two effective forms of birth control starting 1 month prior to acitretin treatment and for 3 years after discontinuation. Prescriber must counsel patient about contraception every month during therapy and every 3 months following discontinuation for at least 3 years.
5) Patient is reliable in understanding and carrying out instructions.
6) Patient has received, and acknowledged, understanding of a careful oral and printed explanation of the hazards of fetal exposure to acitretin and the risk of possible contraception failure. Patient must sign an agreement/informed consent document stating that she understands these risks and that she should not consume ethanol during therapy or for 2 months after discontinuation.
Canadian labeling: Additional contraindications (not in US labeling): Breastfeeding; concomitant use with Vitamin A or other retinoids
Concerns related to adverse effects:
• Capillary leak syndrome: Capillary leak syndrome, a potential manifestation of retinoic acid syndrome (differentiation syndrome) has been reported with acitretin use. Capillary leak syndrome features may include localized or generalized edema with secondary weight gain, fever, and hypotension; rhabdomyolysis and myalgias have also been reported. Laboratory tests may show neutrophilia, hypoalbuminemia, and an elevated hematocrit. Discontinue use if capillary leak syndrome develops during therapy.
• Depression: Depression, including aggressive behavior and thoughts of self-harm have been reported; use with caution in patients with a history of mental illness.
• Exfoliative dermatitis: Exfoliative dermatitis has been reported with acitretin use; discontinue use if exfoliative dermatitis occurs during therapy.
• Lipid effects: Lipid changes, including increased triglycerides, increased cholesterol, and decreased HDL, are common (up to 66%), which were reversible upon discontinuation of treatment; increased triglycerides may lead to pancreatitis. Fatal fulminant pancreatitis has been reported. Use with caution in patients at risk of hypertriglyceridemia (eg, patients with lipid metabolism disturbances, diabetes mellitus, obesity, increased alcohol intake, or a familial history of these conditions). Consider discontinuation if hypertriglyceridemia and decreased HDL persist. Use is contraindicated in patients with chronic abnormally elevated blood lipid values.
• Otic effects: Tinnitus and impaired hearing have been reported with use; consider therapy discontinuation and further evaluation if clinically indicated.
• Photosensitivity: May be photosensitizing; minimize sun or other UV exposure to treated areas. The risk of burning is increased with phototherapy; decreased doses are required.
• Pseudotumor cerebri: Retinoids, including acitretin, have been associated with pseudotumor cerebri (benign intracranial hypertension). Concurrent use of other drugs associated with this effect (eg, tetracyclines) may increase risk. Early signs and symptoms include papilledema, headache, nausea, vomiting, and visual disturbances. Discontinue use in patients experiencing papilledema.
• Skeletal abnormalities: Patients receiving long-term treatment should be periodically examined for bony abnormalities; risk vs benefit of therapy should be considered if abnormalities occur.
• Visual disturbances: May cause adverse effects to the eyes and vision, including a decrease in night vision or decreased tolerance to contact lenses. Use caution when operating vehicles at night; discontinue if visual changes occur.
Disease-related concerns:
• Diabetes: Impaired glucose control has been reported with retinoid use. Use with caution in patients with diabetes mellitus; new cases of diabetes have been diagnosed.
Special populations:
• Pediatric: Safety and efficacy for pediatric patients have not been established; growth potential may be affected. Premature epiphyseal growth plate closure in pediatric patients may occur rarely (AAD/NPF [Menter 2020]).
Other warnings/precautions:
• Subsequent use: Most patients experience relapse of psoriasis after discontinuing therapy. Subsequent courses, when clinically indicated, have produced results similar to the initial course of therapy.
• Worsening of disease: Transient worsening of psoriasis may initially occur; patients should be advised that it may take 2-3 months to achieve the full benefits of treatment.

Important information for females of childbearing potential:
Exclude pregnancy prior to therapy. Acitretin must not be used by patients who intend to become pregnant during therapy or at any time for at least 3 years following discontinuation of acitretin. Use is contraindicated in patients who could become pregnant unless all of the following conditions can be met:
• two negative urine or serum pregnancy tests with a sensitivity of ≥25 mIU per mL before receiving the initial acitretin prescription;
• a pregnancy test every month during treatment;
• use of 2 effective forms of contraception simultaneously (at least one of which must be a primary form, unless absolute abstinence is the chosen method, or the patient has undergone a hysterectomy or is clearly postmenopausal).
Patients who could become pregnant must sign the Patient Agreement/Informed Consent prior to beginning therapy. Only a 1-month supply of the acitretin should be prescribed. Pregnancy testing must be repeated every 3 months for at least 3 years after acitretin is discontinued.
Effective contraception must be used during therapy and for at least 3 years after the last acitretin dose. Effective contraception includes both a primary (tubal ligation, partner's vasectomy, intrauterine devices, birth control pills, and injectable/implantable/insertable/topical hormonal birth control products) and secondary (condoms with or without spermicide, diaphragms and cervical caps which must be used with a spermicide, and vaginal sponges containing a spermicide) form. Microdosed "minipill" progestin preparations are not recommended. Concomitant therapy should be evaluated for potential drug interactions that may decrease the effectiveness of the birth control methods used. A 24-hour number (1-800-739-6700) is available for patients to receive automated birth control and emergency contraception information. Do not use in patients unable to use reliable contraception. Contraception counseling should be repeated monthly during therapy and every 3 months for 3 years after acitretin is discontinued.
Patients who could become pregnant should abstain from ethanol or ethanol-containing products during therapy and for 2 months after the last dose of acitretin.
Prescribing of acitretin should be done only by providers who understand the risk of teratogenicity. Consider use only for patients of childbearing potential with severe psoriasis unresponsive to other therapies or whose clinical condition contraindicates the use of other treatments.
Manufacturer-specific programs have been developed to educate patients of childbearing potential and their health care providers about the serious risks associated with acitretin and to help prevent pregnancies from occurring with the use of this drug and for 3 years after its discontinuation (refer to product-specific labeling).
Important information for males taking acitretin:
Seminal fluid from 3 patients treated with acitretin and 6 patients treated with etretinate have observed the maximal concentration of acitretin in the seminal fluid to be 12.5 ng/mL. Assuming an ejaculate volume of 10 mL, the amount of drug transferred in semen would be 125 ng, which is 1/200,000 of a single 25 mg capsule. Although it appears that residual acitretin in seminal fluid poses little, if any, risk to a fetus, the no-effect limit for teratogenicity is unknown and there is no registry for birth defects associated with acitretin.
Acitretin must not be used by patients who are pregnant.
Acitretin is a metabolite of etretinate; major birth defects have been reported with both etretinate and acitretin. Birth defects in humans include meningomyelocele; meningoencephalocele; multiple synostoses; facial dysmorphia; syndactyly; absence of terminal phalanges; malformations of hip, ankle, and forearm; low-set ears; high palate; decreased cranial volume; cardiovascular malformation; and alterations of the skull and cervical vertebrae. All exposed fetuses have the potential to be affected.
Pregnancy outcome information is available from prospectively (n=318) and retrospectively (n=35) collected data following exposure to etretinate and/or acitretin. Of the 318 prospectively reported pregnancies, conception occurred in 238 cases after the last maternal dose and fetal outcome is known in 118 cases: 15 were abnormal (absent hand/wrist, clubfoot, GI malformation, hypocalcemia, hypotonia, limb malformation, neonatal apnea/anemia, neonatal ichthyosis, placental disorder/death, undescended testicle, and five cases of premature birth), 62 pregnancies were terminated, and 14 ended in spontaneous abortion. Conception occurred ≥1 year after the last dose of etretinate and/or acitretin in the retrospective reports. When conception occurred ≥1 year but <2 years after the last dose of acitretin, birth defects occurred in three cases (including heart malformations, Turner syndrome, and unspecified congenital malformations). When conception occurred ≥2 years after the last dose of acitretin, birth defects occurred in four cases (including foot malformation, cardiac malformations [two cases], and unspecified neonatal and infancy disorder). When conception occurred ≥2 years after the last dose of etretinate, abnormal outcomes were noted in three cases (including chromosome disorder, forearm aplasia, and stillbirth).
If pregnancy occurs during acitretin therapy or at any time for at least 3 years following discontinuation of acitretin, the prescriber and patient should discuss the possible effects on the pregnancy.
Manufacturer-specific programs have been developed to educate patients of childbearing potential and their health care providers about the serious risks associated with acitretin and to help prevent pregnancies from occurring with the use of this drug and for 3 years after its discontinuation. Any pregnancy that occurs during treatment, or at any time for at least 3 years after treatment is discontinued, should be reported to the manufacturer (refer to product-specific labeling) or to the FDA (1-800-FDA-1088).
Acitretin is present in breast milk.
Data are available from a woman who started acitretin 40 mg per day, 8 months postpartum. The woman discontinued breastfeeding prior to the study. Milk samples were collected prior to the first dose and twice daily for 9 days; maternal serum samples were also collected. Acitretin and its metabolite were detected in breast milk. Total concentrations of acitretin + metabolite remained relatively stable over the study period (30 to 40 ng/mL) showing no diurnal variation. Because acitretin is primarily distributed into milk fat, actual concentrations in breast milk may vary depending upon the lipid and fat content of the milk (Rollman 1990).
Due to the potential for serious adverse reactions in the breastfeeding infant, the manufacturer does not recommend acitretin prior to or during breastfeeding. Current guidelines do not recommend use during lactation due to the potential for cumulative toxicity in a breastfeeding infant (AAD/NPF [Menter 2020]; Butler 2014).
Avoid ingestion of additional sources of exogenous vitamin A (in excess of RDA); females of childbearing potential should not ingest ethanol and ethanol-containing products during therapy and for 2 months after the last dose of acitretin.
Lipid profile and LFTs (baseline and at 4-week intervals for the first 3 months, then every 3 months), CBC and renal function tests (baseline, then every 12 weeks) (AAD/NPF [Menter 2020]); blood glucose in patients with diabetes; evaluate for bone abnormalities (with long-term use).
Pregnancy testing in patients of reproductive potential:
• Two negative urine or serum pregnancy tests with a sensitivity of ≥25 mIU per mL before receiving the initial prescription. The first test should be done at the time the decision is made to prescribe acitretin; the second test should be conducted within the first 5 days of the menstrual period immediately prior to the initiation of treatment.
• A pregnancy test with a sensitivity of ≥25 mIU per mL must be repeated monthly during treatment and every 3 months for ≥3 years after discontinuation of acitretin.
Binds to and activates all nuclear subtypes (alpha, beta, and gamma) of retinoid X receptors (RXR) and retinoic acid receptors (RAR) to inhibit the expression of the proinflammatory cytokines interleukin-6 (IL-6), migration inhibitory factor-related protein-8 (MRP-8), and interferon-gamma (markers of hyperproliferation and abnormal keratinocyte differentiation). Resulting actions are anti-inflammatory and antiproliferative, and keratinocyte differentiation is normalized in the epithelium.
Etretinate has been detected in serum for up to 3 years following therapy, possibly due to storage in adipose tissue.
Onset of action: May take 3 to 6 months for full response (AAD/NPF [Menter 2020]); improvement may be seen within 8 weeks.
Absorption: Oral: ~72% absorbed when given with food
Protein binding: >99% bound, primarily to albumin
Metabolism: Metabolized to cis-acitretin; both compounds are further metabolized. Concomitant ethanol use leads to the formation of etretinate (active).
Half-life elimination: Acitretin: 49 hours (range: 33 to 96); cis-acitretin: 63 hours (range: 28 to 157); etretinate: 120 days (range: Up to 168 days)
Time to peak: 2 to 5 hours
Excretion: Feces (34% to 54%); urine (16% to 53%)
Altered kidney function: Plasma concentrations are lower in end-stage renal failure.
Older adult: Higher plasma concentrations are seen; however, no changes occur in the half-life.
