How effective are topical corticosteroids at treating psoriasis?

Dr. Darria Long Gillespie, MD
Emergency Medicine
Corticosteroid drugs are very effective for short-term treatment. The effectiveness of higher-strength forms is similar to that of topical vitamin D. Psoriasis symptoms usually improve in 2 to 4 weeks. Topical corticosteroids should not be used continuously for long periods of time. Your doctor can design a treatment schedule so that you have some steroid-free intervals.
