Treatment can't cure your psoriasis, but it can relieve your symptoms for a while. And you don't have just one or two options. There are many ways to treat it, and you can combine some methods. So if one thing doesn't work, something else likely will.
You and your doctor will decide on a treatment plan based on:
How severe your psoriasis is
What treatments you've already used
Whether you have other medical conditions
How much you’re willing to do
A number of products are available. You can get some over the counter (OTC) at the drugstore, but for others you'll need a prescription. It may take time to find what works best for you.
Choosing a Topical
Moisturizers and lotions that you buy without a prescription can keep your skin moist and help control flare-ups. In general, thick, greasy lotions that trap moisture in your skin work best.
Salicylic acid removes scales that appear on patches of psoriasis. It comes in lotions, gels, soaps, and shampoos. It's especially helpful when used with other skin treatments. Removing flakes of dead skin allows other medications to work better.
Coal tar can help slow the growth of skin cells and make your skin look better. It too comes in many different forms. The weaker products are available OTC. The shampoo is used to help treat scalp psoriasis.
Coal tar doesn't smell good, and it can irritate your skin and stain your clothes.
Follow the directions carefully. Some studies show that the chemicals in coal tar are cancerous, but this is only true at very high doses. It's safe to use these products if you follow your doctor's instructions.
Steroids (corticosteroids) reduce puffiness (inflammation) and slow the growth of skin cells so they don't build up. They come in different strengths. Weaker formulas may work for sensitive areas like the face, neck, or skin fold areas like the groin or armpit. You may need stronger ones for tough-to-treat places like your elbows and knees.
You'll probably apply your treatment twice a day. Your doctor may suggest you wrap the area with tape or plastic after you treat it. This is a method called occlusion. It can help some treatments work better, but it may also make side effects stronger.
