Treating Acne with Antibiotics

When over the counter acne treatments don’t work, dermatologists often prescribe antibiotics to control, reduce or banish acne. These medications work to reduce bacteria and inflammation.

Oral (taken by mouth) antibiotics are usually taken for four to five months and have proved to be very effective in reducing acne. The most commonly used oral antibiotics are Tetracycline, Erythromycin and Minocycline, a form of Tetracycline. All of these medications have side effects, mostly commonly gastrointestinal upset, but the majority of patients tolerate them well with no discomfort. Oral antibiotics are often used for cases of back or chest acne or for patients with sensitive skin who can’t tolerate topical treatments. Unfortunately, bacteria can become tolerant to many oral antibiotics making the treatment ineffective after a time. Antibiotics won’t banish acne forever, though, as it often makes an unwelcome return visit months after the course of treatment is over.

Another negative result of oral antibiotics is the destruction of “good” bacteria that lives in the digestive tract. Those taking antibiotics for more than 6 weeks are also twice as likely to develop upper respiratory infections.

Topical treatments work by drying up oil, killing bacteria that grow in clogged pores and encouraging the sloughing of dead skin cells.

Topical antibiotics come in the forms of gel, lotion or creams and are applied to the skin once or twice daily. The common oral antibiotics are also available as topical applications and have been proven very effective in combating acne with very few side effects. The newest topical antibiotic is Benzamycin, combining erythromycin and benzoyl peroxide and is gaining popularity among dermatologists. Unlike topical tetracycline, benzamycin won’t discolor the skin and very few people report skin irritations with its use. There are very few side effects associated with topical antibiotics. Stinging, dryness or peeling of the skin and mild irritation may occur.

When using topical antibiotics, be sure to wash your face thoroughly, pat (not wipe) it dry and wait at least fifteen minutes before applying the antibiotic. Avoiding aftershave, astringents and or exfoliating products will lessen skin irritation while using topical antibiotics.

Be sure your doctor knows all the prescription or over the counter medications you may be taking before he prescribes antibiotics for you. If you’re pregnant or intending to become pregnant while being treated with antibiotics, be sure your doctor is aware of it.
