TAZORAC
TAZORAC- tazarotene gel
Allergan, Inc.
1 INDICATIONS AND USAGE
1.1 Plaque Psoriasis
TAZORAC® (tazarotene) Gel, 0.05% and 0.1% are indicated for the topical treatment of patients with plaque psoriasis of up to 20% body surface area involvement.
1.2 Acne Vulgaris
TAZORAC (tazarotene) Gel, 0.1% is also indicated for the topical treatment of patients with facial acne vulgaris of mild to moderate severity.
The efficacy of TAZORAC Gel in the treatment of acne previously treated with other retinoids or resistant to oral antibiotics has not been established.
1.3 Limitat ions of Use
The safety of TAZORAC Gel use on more than 20% body surface area has not been established in psoriasis or acne [see Warnings and Precautions ( 5.1) and Use in Specific Populations ( 8.1)].
2 DOSAGE AND ADMINISTRATION
TAZORAC Gel is for topical use only. TAZORAC Gel is not for ophthalmic, oral, or intravaginal use. Avoid accidental transfer of TAZORAC Gel into eyes, mouth, or other mucous membranes. If contact with mucous membranes occurs, rinse thoroughly with water [see Warnings and Precautions ( 5.2)].
Wash hands thoroughly after application.
2. 1 Psoriasis
It is recommended that treatment starts with TAZORAC Gel, 0.05%, with strength increased to 0.1% if tolerated and medically indicated. Apply a thin film (2 mg/cm2) of TAZORAC Gel once per day, in the evening, to cover only the psoriatic lesions on no more than 20% of body surface area. If a bath or shower is taken prior to application, the skin should be dry before applying the gel. If emollients are used, they should be applied at least an hour before application of TAZORAC Gel. Because unaffected skin may be more susceptible to irritation, application of tazarotene to these areas should be carefully avoided. TAZORAC Gel was investigated for up to 12 months during clinical trials for psoriasis.
2. 2 Acne
Cleanse the face gently. After the skin is dry, apply a thin layer (2 mg/cm2) of TAZORAC Gel 0.1% once per day, in the evening, to the skin where acne lesions appear. Use enough to cover the entire affected area. TAZORAC Gel was investigated for up to 12 weeks during clinical trials for acne.
Use effective sunscreens and wear protective clothing while using TAZORAC Gel [see Warnings and Precautions ( 5.3)].
3 DOSAGE FORMS AND STRENGTHS
Gel, 0.05% and 0.1%, in 30 g and 100 g tubes. Each gram of TAZORAC Gel, 0.05% and 0.1% contains 0.5 mg and 1 mg of tazarotene, respectively in a translucent, aqueous gel.
4 CONTRAINDICATIONS
TAZORAC Gel is contraindicated in:
- Pregnancy. Retinoids may cause fetal harm when administered to a pregnant female [see Warnings and Precautions ( 5.1), Use in Specific Populations ( 8.1, 8.3)].
- Individuals who have known hypersensitivity to any of its components [see Warnings and Precautions ( 5.2)].
5 WARNINGS AND PRECAUTIONS
5.1 Embryofetal Toxicity
Based on data from animal reproduction studies, retinoid pharmacology and the potential for systemic absorption, TAZORAC Gel may cause fetal harm when administered to a pregnant female and is contraindicated during pregnancy. Tazarotene elicits malformations and developmental effects associated with retinoids after topical and oral administration to pregnant rats and rabbits during organogenesis.
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.
Although there may be less systemic exposure in the treatment of acne of the face alone due to less surface area for application, tazarotene is a teratogenic substance and causes fetal malformations in animals, and it is not known what level of exposure is required for teratogenicity in humans [see Clinical Pharmacology ( 12.3)].
There were thirteen reported pregnancies in subjects who participated in the clinical trials for topical tazarotene. Nine of the subjects had been treated with topical tazarotene, and the other four had been treated with vehicle. One of the subjects who was treated with tazarotene cream elected to terminate the pregnancy for non-medical reasons unrelated to treatment. The other eight pregnant women who were inadvertently exposed to topical tazarotene during the clinical trials subsequently delivered apparently healthy babies. As the exact timing and extent of exposure in relation to the gestation times are not certain, the significance of these findings is unknown.
Females of Child-bearing Potential
Females of child-bearing potential should be warned of the potential risk and use adequate birth-control measures when TAZORAC Gel 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 result for pregnancy test should be obtained within 2 weeks prior to TAZORAC Gel therapy. TAZORAC Gel therapy should begin during a normal menstrual period [see Use in Specific Populations ( 8.1)].
5.2 Local Irritation and Hypersensitivity Reactions
Application of TAZORAC Gel may cause excessive irritation in the skin of certain sensitive individuals. Local reactions (including blistering and skin desquamation, pruritus, burning, erythema) and hypersensitivity adverse reactions (including urticaria) have been observed with topical tazarotene.
If these adverse reactions occur, consider discontinuing the medication or reducing the dosing frequency, as appropriate, until the integrity of the skin is restored. Alternatively, patients with psoriasis who are being treated with the 0.1% concentration can be switched to the lower concentration. Frequency of application should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance. Therapy can be resumed, or the drug concentration or frequency of application can be increased as the patient becomes able to tolerate treatment.
Concomitant topical medications and cosmetics that have a strong drying effect should be avoided. It is also advisable to “rest” a patient’s skin until the effects of such preparations subside before treatment with TAZORAC Gel is initiated.
TAZORAC Gel, should not be used on eczematous skin, as it may cause severe irritation.
Weather extremes, such as wind or cold, may be more irritating to patients using TAZORAC Gel.
5.3 Photosensitivity and Risk for Sunburn
Because of heightened burning susceptibility, exposure to sunlight (including sunlamps) should be avoided unless deemed medically necessary, and in such cases, exposure should be minimized during the use of TAZORAC Gel. Patients must be warned to use sunscreens and protective clothing when using TAZORAC Gel. Patients with sunburn should be advised not to use TAZORAC Gel 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 TAZORAC Gel.
TAZORAC Gel 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.
