Downsides and risks
› 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.
