The first step in treating dermatitis is to identify and eliminate the cause. Most mild skin inflammation responds well to room temperature baths followed by application of fragrance-free moisturising lotions or over-the-counter hydrocortisone cream.
Seborrhoeic dermatitis may respond to anti-dandruff shampoo. These products may contain tar, salicylic acid , zinc pyrithione, ketoconazole , sulfur or selenium , any of which may be effective.
Once chemicals causing contact dermatitis are identified, treatment will be based on avoidance, symptom relief and other coping mechanisms.
To help clear the lesions of nummular dermatitis, applying a moisturising lotion and corticosteroid cream may be recommended.
If you suffer from stasis dermatitis, wearing support stockings and elevating your legs to reduce their swelling may be advised. Also, the underlying condition that is causing the leg swelling should be controlled. If an open ulcer gets infected, antibiotics may be needed.
To reduce inflammation and heal the irritation of most types of dermatitis, a doctor will usually recommend a prescription corticosteroid cream and may prescribe an oral antihistamine to relieve severe itching and an antibiotic if a secondary infection develops. Severe cases of dermatitis may call for corticosteroid tablets or, in rare cases, injections.
The best treatment has been tetracycline pills or minocycline pills. You take one pill a day on an empty stomach for a month. Tetracycline is pretty safe at this dose. It is completely destroyed by food. So, you must take it with your stomach empty for an hour before and after you take the pill. Tetracycline could make you more sensitive to sunburn. Be sure to use a sunscreen if you are going to be in the sun such as skiing or swimming. Rarely tetracycline can cause a yeast infection of the vagina. This is characterized by a thick white cheesy vaginal discharge that causes itching around the vagina. If that happens, stop the tetracycline and let me know.
A dermatologist diagnoses perioral dermatitis by examination. No other tests are usually done. The first step in treating perioral dermatitis is to discontinue all topical steroid creams , even non-prescription hydrocortisone. Once the steroid cream is discontinued, the rash appears and feels worse for days to weeks before it starts to improve. Heavy face creams should also be stopped. One must resist the temptation to apply any of these creams to the face when this happens. Think of the face as a cream junkie that needs a "fix"- one needs to go "cold-turkey".
