Erythromycin When Doxycycline Fails

While doxycycline is a first-line oral treatment for inflammatory rosacea, not everyone responds to or can tolerate it. In these cases, another antibiotic with anti-inflammatory properties, erythromycin, can be considered as an alternative.

Does it work for rosacea?

Yes, there is evidence that erythromycin is effective in treating the papules and pustules (red bumps and spots) of rosacea. It can be a useful option for patients who experience side effects from tetracycline-class antibiotics (like doxycycline or lymecycline) or for whom those medications have proven ineffective.

When is it used and how?

Erythromycin is usually considered as a second line option for patients who cannot take tetracyclines or for whom tetracyclines have not proven effective.

About Dr Magnus Lynch

I am a London-based Consultant Dermatologist and Dermatological Surgeon. I am highly experienced in skin cancer diagnosis, Mohs micrographic surgery, acne, rosacea, acne scarring and laser treatments. I studied at the Universities of Cambridge and Oxford, and completed my dermatology training and Mohs fellowship at the prestigious St John’s Institute of Dermatology. I graduated from medical school in 2003 and have worked exclusively in Dermatology since 2012.

I lead a research team at King’s College London investigating the molecular biology of skin cancer. In recent years I have been involved in Media Appearances, including the Channel 5 series 'Skin A&E', where I perform skin surgeries and treat various skin conditions. Filming for the next series has recently completed and the series will be released later in 2025.

My NHS practice is at Guy's Hospital. I consult with private patients at the London Bridge Hospital, OneWelbeck (near to Bond Street station) and on Harley Street. A new consultation is £250. Book A Consultation.
