Considerations: Ask your doctor before using any other products on your skin while using erythromycin, as it may be too irritating. This includes other prescriptions, over-the-counter medicines (including those listed on this site), and harsh or abrasive cleansers, perfumes, or make-up.2 People report burning as the most frequent side effect, and also peeling, dryness, itching, redness, and oiliness, among others.2
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
