🩺 Clinical
Tazarotene (Tazorac, Fabior) is used to treat acne. Tazarotene (Tazorac) is also used to treat psoriasis (a skin disease in which red, scaly patches form on some areas of the body). Tazarotene (Avage) is used to reduce facial wrinkling and discoloration in patients who are also using other skin care and sunlight avoidance programs. Tazarotene is in a class of medications called retinoids. It works to treat acne and psoriasis by slowing skin cell overgrowth and decreasing skin cell inflammation, which can lead to acne or psoriasis.

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⛔ Contraindications ▾
4 CONTRAINDICATIONS FABIOR Foam is contraindicated in pregnancy. FABIOR Foam may cause fetal harm when administered to a pregnant woman. Tazarotene elicits teratogenic and developmental effects associated with retinoids after topical or systemic administration in rats and rabbits [see Use in Specific Populations (8.1) ].
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, treatment should be discontinued and the patient apprised of the potential hazard to the fetus [see Warnings and Precautions (5.1) , Use in Specific Populations (8.1) ]. Pregnancy. ( 4 , 8.1 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Fetal Risk: FABIOR Foam contains tazarotene, which is a teratogenic substance. FABIOR Foam is contraindicated in pregnancy. Females of childbearing potential should have a negative pregnancy test within 2 weeks prior to initiating treatment and use an effective method of contraception during treatment.
( 5.1 ) Local Irritation: Use with caution in patients with a history of local tolerability reactions or local hypersensitivity. ( 5.2 ) Potential Irritant Effect with Concomitant Topical Medications: Use with caution because a cumulative irritant effect may occur. ( 5.3 ) Photosensitivity and Risk for Sunburn: Avoid exposure to sunlight, sunlamps, and weather extremes.
Wear sunscreen daily. ( 5.4 ) Contents are flammable. Instruct the patient to avoid fire, flame, and smoking during and immediately following application.
( 5.5 )
5.1Fetal Risk Systemic exposure to tazarotenic acid is dependent upon the extent of the body surface area treated. In patients treated topically over sufficient body surface area, exposure could be in the same order of magnitude as in orally treated animals. Tazarotene is a teratogenic substance, and it is not known what level of exposure is required for teratogenicity in humans [see Clinical Pharmacology (12) ] .
There were 5 reported pregnancies in subjects who participated in clinical trials for topical tazarotene foam. One of the subjects was found to have been treated with topical tazarotene for 25 days, 2 were treated with vehicle foam, and the other 2 did not receive either tazarotene foam or vehicle foam. The subjects were discontinued from the trials when their pregnancy was reported.
The one pregnant woman who was inadvertently exposed to topical tazarotene during the clinical trial delivered a full-term healthy infant. Females of Childbearing Potential: Females of child-bearing potential should be warned of the potential risk and use adequate birth-control measures when tazarotene foam is used. The possibility of pregnancy should be considered in females of child-bearing potential at the time of institution of therapy.
A negative serum or urine result for pregnancy test having a sensitivity down to at least 25 mIU/mL for human chorionic gonadotropin (hCG) should be obtained within 2 weeks prior to therapy with FABIOR Foam, which should begin during a normal menstrual period for females of childbearing potential. Advise patients of the need to use an effective method of contraception to avoid pregnancy [see Use in Specific Populations (8.1) ] .
5.2Local Irritation FABIOR Foam should be used with caution in patients with a history of local tolerability reactions or local hypersensitivity. Retinoids should not be used on abraded or eczematous skin, as they may cause severe irritation. Contact with the mouth, eyes, and mucous membranes should be avoided.
In case of accidental contact, rinse well with water. Some individuals may experience skin redness, peeling, burning or excessive pruritus. If these effects occur, the medication should either be discontinued until the integrity of the skin is restored, or the dosing should be reduced to an interval the patient can tolerate.
However, efficacy at reduced frequency of application has not been established. Weather extremes, such as wind or cold, may be more irritating to patients using FABIOR Foam.
5.3Potential Irritant Effect with Concomitant Topical Medications Concomitant topical acne therapy should be used with caution because a cumulative irritant effect may occur. If irritancy or dermatitis occurs, reduce frequency of application or temporarily interrupt treatment and resume once the irritation subsides. Treatment should be discontinued if the irritation persists.
5.4Photosensitivity and Risk for Sunburn Because of heightened burning susceptibility, exposure to sunlight (including sunlamps) should be avoided. Patients must be warned to use sunscreens and protective clothing when using FABIOR Foam. Patients with s…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions reported at an incidence ≥6% are application site irritation, application site dryness, application site erythema, and application site exfoliation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Mayne Pharma at 1-844-825-8500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch
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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data reflect exposure to FABIOR Foam in 744 subjects with acne vulgaris. Subjects were aged 12 to 45 years and were treated once daily in the evening for 12 weeks.
Adverse reactions reported in ≥ 1% of subjects treated with FABIOR Foam are presented in Table 1. Most adverse reactions were mild to moderate in severity. Severe adverse reactions represented 3.0% of the subjects treated.
Overall, 2.7% (20/744) of subjects discontinued FABIOR Foam because of local skin reactions. Table 1. Incidence of Adverse Reactions in ≥1 % of Subjects Treated with FABIOR Foam FABIOR Foam N = 744 Vehicle Foam N = 741 Patients with any adverse reaction, n (%) 163 (22) 19 (3) Application site irritation 107 (14) 9 (1) Application site dryness 50 (7) 8 (1) Application site erythema 48 (6) 3 (<1) Application site exfoliation 44 (6) 3 (<1) Application site pain 9 (1) 0 Application site photosensitivity (including sunburn) 8 (1) 3 (<1) Application site pruritus 7 (1) 3 (<1) Application site dermatitis 6 (1) 1 (<1) Additional adverse reactions that were reported in <1% of subjects treated with FABIOR Foam included application site reactions (including discoloration, discomfort, edema, rash, and swelling), dermatitis, impetigo, and pruritus.
Local skin reactions, dryness, erythema, and peeling actively assessed by the investigator and burning/stinging and itching reported by the subject were evaluated at baseline, during treatment, and end of treatment. During the 12 weeks of treatment, each local skin reaction peaked at Week 2 and gradually reduced thereafter with the continued use of FABIOR Foam.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS No formal drug-drug interaction studies were conducted with FABIOR Foam. Concomitant dermatologic medications and cosmetics that have a strong drying effect should be avoided. It is recommended to postpone treatment until the effects of these products subside before use of FABIOR Foam is started.
Concomitant use with oxidizing agents, such as benzoyl peroxide, may cause degradation of tazarotene and may reduce the clinical efficacy of tazarotene. If combination therapy is required, they should be applied at different times of the day (e.g., one in the morning and the other in the evening). The impact of tazarotene on the pharmacokinetics of progestin-only oral contraceptives (i.e., minipills) has not been evaluated.
In a trial of 27 healthy female subjects between the ages of 20 to 55 years receiving a combination oral contraceptive tablet containing 1 mg norethindrone and 35 mcg ethinyl estradiol, concomitant use of tazarotene did not affect the pharmacokinetics of norethindrone and ethinyl estradiol over a complete cycle. Avoid concomitant dermatologic medications and cosmetics that have a strong drying effect. ( 7 )
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy FABIOR Foam is contraindicated in pregnancy [see Contraindications (4) ]. There are no adequate and well-controlled studies with FABIOR Foam in pregnant women. FABIOR Foam is contraindicated in females who are or may become pregnant [see Contraindications (4) ].
Females of child-bearing potential should be warned of the potential risk and use adequate birth-control measures when FABIOR Foam is used. The possibility that a female of child-bearing potential is pregnant at the time of institution of therapy should be considered. A negative serum or urine result for pregnancy test having a sensitivity down to at least 25 mIU/mL for hCG should be obtained within 2 weeks prior to therapy with FABIOR Foam, which should begin during a normal menstrual period for females of childbearing potential.
In rats, tazarotene 0.05% gel administered topically during gestation days 6 through 17 at 0.25 mg/kg/day resulted in reduced fetal body weights and reduced skeletal ossification. Rabbits dosed topically with 0.25 mg/kg/day tazarotene gel during gestation days 6 through 18 were noted with single incidences of known retinoid malformations, including spina bifida, hydrocephaly, and heart anomalies. Systemic exposure (AUC) to tazarotenic acid at topical doses of 0.25 mg/kg/day tazarotene in a gel formulation in rats and rabbits were 15 and 166 times, respectively, the AUC in acne patients treated with 2 mg/cm 2 of FABIOR Foam 0.1% over a 15% body surface area.
As with other retinoids, when tazarotene was administered orally to experimental animals, developmental delays were seen in rats, and teratogenic effects and post-implantation loss were observed in rats and rabbits at doses 13 and 325 times, respectively, the AUC to tazarotenic acid in acne patients treated with 2 mg/cm 2 of FABIOR Foam 0.1% over a 15% body surface area. In female rats orally administered 2 mg/kg/day tazarotene from 15 days before mating through gestation day 7, a number of classic developmental effects of retinoids were observed including decreased number of implantation sites, decreased litter size, decreased numbers of live fetuses, and decreased fetal body weights.
A low incidence of retinoid-related malformations was also observed. AUC in rats was 42 times the AUC in acne patients treated with 2 mg/cm 2 of FABIOR Foam 0.1% over a 15% body surface area.
8.3Nursing Mothers After single topical doses of 14 C-tazarotene to the skin of lactating rats, radioactivity was detected in milk, suggesting that there would be transfer of drug-related material to the offspring via milk. It is not known whether this drug is excreted in human milk. The safe use of FABIOR Foam during lactation has not been established.
A decision should be made whether to discontinue breastfeeding or to discontinue therapy with FABIOR Foam taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
8.4Pediatric Use The safety and effectiveness of FABIOR Foam in pediatric patients younger than 12 years have not been established. Clinical studies of FABIOR Foam included 860 patients aged 12 to 17 years with acne vulgaris.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Tazarotene is a retinoid prodrug that is converted to its active form, the cognate carboxylic acid of tazarotene, by rapid deesterification in animals and man. Tazarotenic acid binds to all 3 members of the retinoic acid receptor (RAR) family: RARα, RARβ, and RARγ but shows relative selectivity for RARβ and RARγ and may modify gene expression. The clinical significance of these findings is unknown.
The mechanism of tazarotene action in acne vulgaris is not defined. However, the basis of tazarotene's therapeutic effect in acne may be due to its anti-hyperproliferative, normalizing-of-differentiation and anti-inflammatory effects. Tazarotene inhibited corneocyte accumulation in rhino mouse skin and cross- linked envelope formation in cultured human keratinocytes.
The clinical significance of these findings is unknown.
12.2Pharmacodynamics The pharmacodynamics of FABIOR Foam are unknown.
12.3Pharmacokinetics Following topical application, tazarotene undergoes esterase hydrolysis to form its active metabolite, tazarotenic acid. Tazarotenic acid was highly bound to plasma proteins (greater than 99%). Tazarotene and tazarotenic acid were metabolized to sulfoxides, sulfones, and other polar metabolites which were eliminated through urinary and fecal pathways.
Systemic exposure following topical application of FABIOR Foam 0.1% was evaluated in one trial. Patients aged 15 years and older with moderate-to-severe acne applied approximately 3.7 grams of FABIOR Foam 0.1% (N = 13) to approximately 15% body surface area (face, upper chest, upper back, and shoulders) once daily for 22 days. On Day 22, the mean (±SD) tazarotenic acid C max was 0.43 (±0.19) ng/mL, the AUC 0 - 24h was 6.98 (±3.56) ng∙h/mL, and the half-life was 21.7 (±15.7) hours.
The median T max was 6 hours (range: 4.4 to 12 hours). The AUC 0-24h for tazarotenic acid was approximately 50-fold higher compared with the parent compound tazarotene. The mean (±SD) half-life of tazarotene was 8.1 (±3.7) hours.
Accumulation was observed upon repeated once-daily dosing as the tazarotenic acid predose concentrations were measurable in the majority of subjects. Steady state was attained within 22 days of daily application. Once-daily dosing resulted in little to no accumulation of tazarotene as predose concentrations were mostly below the quantitation limit throughout the study.
