Erythromycin is an antibiotic in the Macrolide Family. It is a widely used antibiotic that can be applied topically or ingested orally. Erythromycin is used to treat many types of bacterial infections, including those of the respiratory tract, urinary tract and skin.

Erythromycin is commonly used for the treatment of acne symptoms. Topical erythromycin is a popular choice for treating mild to moderate acne symptoms (Acne Types: 1-3). Oral Erythromycin is occasionally used as an acne treatment, but other Macrolide family antibiotics are often preferred for oral use because they tend to have fewer side effects.

Many clinical research and patient reports have shows Erythromycin can be an effective treatment for many individuals with acne. Antibiotic susceptibility testing indicates that the acne-causing P. acnes bacterium is generally sensitive to Macrolide family antibiotics, including Erythromycin. However, P. acnes bacteria that are resistant to Erythromycin and other Macrolide antibiotics are becoming common in many regions of the world. Individuals with acne symptoms caused by these resistant bacteria are not likely to benefit from treatment with Erythromycin.

Erythromycin is often combined with benzoyl peroxide in topical formulations (eg. Benzamycin). Topical Erythromcyin is often combined with complementary treatments (eg. Oral Antibiotics, Retinoids, Hormonal Treatments, etc) as part of a comprehensive acne treatment plan.
