Upsides
  • Available over-the-counter from many brands.
  • Benzac (benzoyl peroxide) comes in many different forms and combinations with other acne products.
  • Applying erythromycin to the skin reduces the amount of acne bacteria and "calms" the skin down (lowers the inflammatory response) in acne.
  • Available in a gel formulation which may be better if your skin is very oily.
  • Better choice if you're pregnant. erythromycin is categorized as pregnancy Category B (likely safe) as compared to similar topical medicines that are Category C (weigh risks vs benefits).
Downsides
  • Benzac (benzoyl peroxide) increases your skin's sensitivity to the sun and may also cause dryness or stinging.
  • Be careful when applying Benzac (benzoyl peroxide) to large areas since it can bleach hair, clothing, and pillow cases upon contact.
  • Benzac (benzoyl peroxide) needs to be combined with other medications to effectively treat severe acne.
  • There's a risk of irritation with anything you apply to your skin and this is no different. erythromycin, like other topical antibiotics, can cause skin irritation and may appear as redness, peeling, abnormal dryness or stinging, tightening, or burning sensations.
  • It's rare, that a serious allergic reaction would occur, but it's a good idea to test a small area of skin before using on any larger or sensitive areas
  • Studies show it works better when combined with other topical medicines to fight acne and reduce the risk of it losing its effectiveness over time.
  • Can cause severe inflammation of the large intestine (pseudomembranous colitis)
  • Stop using if you don't notice any improvement in your acne after 6-8 weeks. The most time you can use it is three months.
