Are Topical steroids effective?

Topical steroids. Topical steroid medications are one of the most common treatments for mild to moderate psoriasis. They reduce redness (inflammation) and itching and stop the rapid build-up of dead skin cells. They come in varying strengths, from weak to highly potent and are available as creams, gels, lotions, ointments, or solutions. Generally stronger preparations are used on the scalp, knees, palms and feet while weaker creams or ointments are used on the face and other sensitive areas. A new foam for scalp psoriasis called clobetasol propionate has recently been approved. In foam form, it penetrates the skin easily - enhancing the effectiveness of the treatment.

Topical steroids can become less effective if used repeatedly for a long time. This is called resistance. The best outcome may be achieved when topical steroids are combined with other medications applied to the skin. However, steroid medication should not be stopped suddenly.

Steroids in the form of pills or injections are generally not used to treat psoriasis because they have too many serious side effects.

Long-term use of potent topical steroids on large areas of skin can produce side effects such as stretch marks, thinning and skin color changes, plus the appearance of small blood vessels through the skin. These medications should not be put on the face or on areas of the body where the skin folds, such as the armpits, groin, and between the toes.
