Rosacea Treatment:

Oral Antibiotics - Erythromycin

Erythromycin is an antibiotic that is often used to treat rosacea symptoms, and are available in topical form as well as oral pills. Generally, the effects are swifter when taken orally, and more powerful. It is also more convenient for the patients.


Oral erythromycin should be taken once or twice a day, or as otherwise directed by your doctor.

Expected results:

Effects can be seen after two or three weeks, and further improvement can be seen for several months.

How it works:

Erythromycin is a powerful antibiotic, but in rosacea treatment, its anti-inflammatory effects are the main effects that are sought.


Gastro-intestinal problems are the most common unwanted side-effects in using erythromycin. Rarely, liver toxicity, pancreatitis, and ear infections (in those with kidney problems) can occur. Consult your doctor as soon as possible any of these problems arise.
