Certain Mouth Rashes Don't Respond to Topical Steroid Treatments
You've been treating a persistent rash around your mouth with medicated ointments, but it's not going away. The problem may be the ointment — it could actually be sustaining the particular rash you have.
Peri-oral dermatitis is a scaly rash with small bumps (some filled with pus) around the mouth, eyes or nose. It's especially common among women ages 20-45, possibly due to hormonal factors or cosmetic use. Other than its unattractiveness you might not otherwise notice it, although it can cause stinging, itching or burning. There are ways to treat it effectively, though not necessarily the way you might think.
Many skin conditions respond well to topical steroids, like ointments or lotions containing hydrocortisone. But prolonged use of a steroid for skin irritations might actually increase risks for peri-oral dermatitis. Applying it to an existing rash may also deceive you — the steroid constricts some of the skin's tinier blood vessels, which will make the rash appear as if it's fading. The effect, though, usually doesn't last more than an hour. If you continue to use the steroid, the rash won't get better.
The key to alleviating peri-oral dermatitis requires treatment from a physician, dermatologist or dentist, who will also be able to accurately diagnose the specific skin condition you have. If it is peri-oral dermatitis, the first step is to stop using any topical steroids and only wash with mild soap or similar substitute. You'll have to be patient because the rash may at first appear to flare up and worsen before getting better.
Instead of steroids, we may prescribe antibiotics to help clear the rash, typically tetracycline. It may take several weeks of use before the rash begins to clear; as it does clear, you would either stop the antibiotic treatment or taper off over a four-to-five week period.
While some cases of peri-oral dermatitis will clear up and remain that way, some people may experience chronic reoccurrences. Even so, by using the same treatment approach we can still effectively manage the condition for the long-term.
