Fabior Prescribing Information
FABIOR® (tazarotene) Foam, 0.1% is indicated for the topical treatment of acne vulgaris in patients 12 years of age or older.
FABIOR Foam is for topical use only. FABIOR Foam is not for oral, ophthalmic, or intravaginal use.
FABIOR Foam should be applied once daily in the evening after washing with a mild cleanser and fully drying the affected area. Dispense a small amount of foam into the palm of the hand. Using fingertips, apply only enough foam to lightly cover the entire affected areas of the face and/or upper trunk with a thin layer; gently massage the foam into the skin until the foam disappears. Avoid the eyes, lips, and mucous membranes. Wash hands after application.
Patients may use moisturizer as needed.
If undue irritation (redness, peeling, or discomfort) occurs, patients should reduce frequency of application or temporarily interrupt treatment. Treatment may be resumed once irritation subsides. Treatment should be discontinued if irritation persists.
0.1%, white to off-white foam
Pregnancy
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/cm2 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/cm2 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/cm2 of FABIOR Foam 0.1% over a 15% body surface area.
Nursing Mothers
After single topical doses of 14C-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.
Pediatric 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.
Geriatric Use
FABIOR Foam for the treatment of acne has not been clinically evaluated in persons over the age of 65.
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)].
Fetal 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)].
Local 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.
Potential 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.
Photosensitivity 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 sunburn should be advised not to use FABIOR Foam until fully recovered. Patients who may have considerable sun exposure due to their occupation and those patients with inherent sensitivity to sunlight should exercise particular caution when using FABIOR Foam and ensure that the precautions are observed [see FDA-approved patient labeling]. Due to the potential for photosensitivity resulting in greater risk for sunburn, FABIOR Foam should be used with caution in patients with a personal or family history of skin cancer.
FABIOR Foam should be administered with caution if the patient is also taking drugs known to be photosensitizers (e.g., thiazides, tetracyclines, fluoroquinolones, phenothiazines, sulfonamides) because of the increased possibility of augmented photosensitivity.
Flammability
The propellant in FABIOR Foam is flammable. Instruct the patient to avoid fire, flame, and/or smoking during and immediately following application.
