How does this medication work? What will it do for me?
This combination product contains two medications: halobetasol and tazarotene. Tazarotene belongs to a group of medications called retinoids. Halobetasol belongs to the family of medications called topical corticosteroids. In combination they are used to treat the signs and symptoms of moderate-to-severe plaque psoriasis.
Tazarotene is believed to help psoriasis by reducing inflammation and keeping skin cell growth down to a normal rate. Halobetasol helps to control redness, itchiness, and irritation of the skin by reducing inflammation.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Absorption: Absorption of the medication into the bloodstream may lead to adrenal suppression (reduction of the body's reaction to stressful situations) and side effects, especially if the lotion is used over large areas or for an extended period of time. Occasionally, symptoms of steroid withdrawal may develop when the medication is stopped after prolonged use.
Circulation problems: Topical corticosteroids should be used with caution by people with skin diseases associated with impaired circulation.
Eczema: Retinoids can cause severe irritation of eczema. If you have eczema, your doctor will monitor your condition while you are using halobetasol-tazarotene.
Exposure to sunlight: This medication can make the skin more sensitive to sunlight. This may be made worse if you are taking other medications that cause sensitivity to sunlight (e.g., tetracyclines, quinolone antibiotics, "sulfa" antibiotics). Make sure you use sunscreen (minimum SPF 30) and protective clothing when exposed to sunlight. If you have a sunburn, do not use halobetasol-tazarotene until you have fully recovered.
Infection: Topical corticosteroids may increase the risk of developing a skin infection. Contact your doctor if you notice any increased redness, swelling, heat or pain around the area where the medication is applied, as these are possible signs of infection.
Skin irritation: Halobetasol - tazarotene may cause skin irritation. If this happens you may need to use this mediation less frequently. If local irritation or sensitization develops, call your doctor.
Vision: This medication may increase the risk of developing glaucoma or cataracts. If you have glaucoma, it may make symptoms of glaucoma worse. Report any changes in vision to your doctor as soon as possible.
Pregnancy: Halobetasol - tazarotene should not be used during pregnancy. If you may become pregnant, you should use an effective method of birth control while using this medication, and you should start using halobetasol - tazarotene only after you have confirmed that you are not pregnant. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if tazarotene or halobetasol passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.
Seniors: The safety and effectiveness of using this medication have not been established for people older than 65 years of age. Seniors tend to have fragile skin and other diseases that make them more likely to experience side effects of this medication.
