Acne: Prescription Lotions and Gels

Prescription Lotions and Gels for Acne Treatment
If treatment with benzoyl peroxide doesn’t get your pimples under control within a couple of months, check with a physician. Dermatologists often prescribe topical antibiotic gels or lotions in addition to or instead of benzoyl peroxide. Erythromycin and clindamycin are old standbys. Because they have been so widely used however, bacteria have begun to develop resistance to them. As a result, dermatologists have been restricting their use and instead turning to other approaches.
One other medication that is being prescribed is azelaic acid (Azelex, Finevin). Like benzoyl peroxide, this topical treatment seems to keep pores from clogging and to discour-age the multiplication and spread of bacteria. It too may result in burning, stinging, redness, or dryness of the skin. In rare instances, dark skin exposed to azelaic acid may develop lighter patches. If you have a cold sore or fever blister that gets worse while you are using an azelaic acid product, notify the prescribing physician immediately.
Isotretinoin or a similar compound in the vitamin A family can be very effective in treating acne and reducing the inflammation associated with severe acne. Using topical vitamin A–like compounds (retinoids) early in the course of acne lessens the likelihood of scarring, a complication of the condition. Some doctors prescribe tretinoin together with benzoyl peroxide or with an oral antibiotic such as doxycycline to clear the skin faster.
Clindamycin Gel (Cleocin T, Clinda-Derm, Evoclin Topical Foam
Clindamycin is an antibiotic that can be applied to the skin to fight acne-causing bacteria. It may take 2 months to see significant improvement, but generally this treatment is effective. Other topical antibiotics such as erythromycin gel are also effective. Some prescription products combine an antibiotic with benzoyl peroxide for greater effectiveness. These include BenzaClin and Duac Gel (clindamycin plus benzoyl peroxide) and Benzamycin (erythromycin plus benzoyl peroxide). These are effective but expensive because no generic equivalents are available.
Side effects: Itching, burning, dryness, and peeling. A rare but very serious and dangerous side effect of clindamycin that is extremely unlikely to occur but still possible with the topical form is pseudomembranous colitis. Notify your doctor immediately if you develop persistent or bloody diarrhea.
Downside: Skin bacteria (P. aches) are beginning to develop resistance to topical clindamycin.
Cost: Approximately $50 for a 60-gram tube Tretinoin Gel (Retin-A).
Retin-A speeds up cell turnover and normalizes the lower levels of the skin. With 6 weeks or more of treatment, it is frequently very helpful against acne.
Side effects: Stinging, dryness, redness, flaking, and irritation.
Downside: Retin-A makes skin more sensitive to sunburn and sun damage, so stay out of the sun and use effective protection against ultraviolet rays.
Cost: $35 to $50 for 15 grams.
There is another prescription gel or cream that is based on a vitamin. Nicomide-T gel or cream contains nicotinamide, a form of niacin. Like Retin-A, it is topical but not an antibiotic, so theoretically bacteria should not develop resistance to it. A preliminary study showed that Nicomide-T gel is as effective as clindamycin gel in reducing blemishes.” Other research confirmed that it can protect the skin and is less likely to dry it than a number of other acne treatments. It is not clear whether Nicomide-T is as effective as Retin-A, though some studies conducted by the manufacturer, Sirius Laboratories, suggest that adding it to other treatments boosts the effectiveness of both.
