5) Retinoids:
Retinoids are a class of drugs that include tazarotene. They are used in the management of conditions like acne, some types of skin cancers and some inflammatory conditions like psoriasis. It helps reduce the rate of division of skin cells, reduce inflammation and decreases skin thickness. Retinoids in general can be given topically in the form of a cream or systemically as pills or injections.
Topical medications are the ones usually used in psoriasis and they tend to have fewer side effects than those given systemically. They are, however, also contraindicated in pregnancy and effective contraception is a must during therapy. The most common side effects with retinoids include skin reactions in the form of redness and scaling.
