By Mayo Clinic staffThere's no treatment that's guaranteed to stop seborrheic dermatitis forever, but treatments can control its signs and symptoms. Treatment depends on your skin type, the severity of your condition and where it appears on your body.
Seborrheic dermatitis of the scalp
Medicated shampoos are the first step in treating seborrheic dermatitis of the scalp. Choose an over-the-counter shampoo that contains one of the following ingredients:
- Ketoconazole
- Ciclopirox
- Tar
- Pyrithione zinc
- Selenium sulfide
- Salicylic acid
Try using the shampoo daily until your symptoms are controlled; then cut back to two or three times a week. If one type of shampoo works for a time and then seems to lose its effectiveness, try alternating between two types of dandruff shampoos. Leave the shampoo on for three to five minutes — this allows the ingredients time to work.
If you've shampooed faithfully for several weeks and you're still experiencing an itchy, flaky scalp, talk to your doctor or dermatologist. You may need a prescription-strength shampoo or more aggressive treatment with a steroid lotion.
Seborrheic dermatitis on the face and body
Treatments for nonscalp seborrheic dermatitis aim to reduce inflammation and the buildup of scaling on the skin. Over-the-counter (nonprescription) antifungal or anti-itch creams, along with other self-care measures, may help control your symptoms.
If these measures don't help, your doctor may prescribe topical corticosteroids, antifungal medications or a combination of the two to treat stubborn patches. A common course of treatment includes a daily regimen of ketoconazole (Nizoral) and desonide (Desowen) applied to your skin. Prescription oral medication, such as terbinafine (Lamisil), may be an option if the condition affects a large portion of your body.
A class of medications called immunomodulators, such as tacrolimus (Protopic) and pimecrolimus (Elidel), affects the immune system. These medications have anti-inflammatory and mild antifungal properties and are effective in treating seborrheic dermatitis. Due to possible concerns about the effect of these medications on the immune system when used for prolonged periods of time, the Food and Drug Administration (FDA) recommends that Elidel and Protopic be used only after other treatments have failed, or if someone can't tolerate other treatments. Additionally, the FDA advises against long-term use of these medications.
