About

What is Erythromycin?

Erythromycin 2.0% is a prescription topical antibiotic used to treat acne vulgaris. It is applied directly to the skin and is designed to help manage acne as part of a consistent treatment routine. As a macrolide antibiotic, it works locally in the skin and should be used under the guidance of a healthcare provider.

  • A prescription treatment for acne vulgaris
  • A topical macrolide antibiotic
  • Applied directly to acne-prone areas of the skin
  • Intended for regular, ongoing use
  • Not for use in the eyes, mouth, or mucous membranes

How do I take Erythromycin?

Erythromycin 2.0% is typically applied as a thin film to the affected skin once or twice daily after cleansing and drying the area. It should be spread lightly across the full area where acne appears, rather than used only on individual spots.

  • Apply a thin layer once or twice daily
  • Cleanse and dry the skin before use
  • Spread lightly over the affected area
  • Avoid contact with eyes, nose, mouth, and sensitive areas
  • For external use only

What are the possible side effects?

Erythromycin 2.0% may cause local skin reactions such as burning, dryness, peeling, itching, or redness at the application site. Although it is applied to the skin, antibiotic-related side effects can still occur. In rare cases, diarrhea may develop and could be a sign of a more serious condition.

  • Common effects include burning, dryness, peeling, or irritation
  • Some people may notice redness or itching
  • Eye irritation can occur if the product gets into the eyes
  • Stop use and contact your provider if severe skin reactions develop
  • Seek medical care if you experience persistent diarrhea or unusual gastrointestinal symptoms

*Prescription products require an online consultation with a licensed healthcare provider who will determine if treatment is appropriate. Individual results may vary.

  • Avoid combining with other irritating products
  • Restart only if your skin tolerates it
  • Contact your provider if symptoms persist

Your provider can help you decide whether to continue or modify your treatment.

Your provider can help you build a safe and effective routine.
