Is application of erythromycin on the face harmful?
Q: I had lots of pimples, so I consulted a skin specialist who recommended me to apply acnesol gel on my face which contains erythromycin. I read in newspaper that erythromycin is used as an antibiotic and it is very harmful for health. It causes high blood preasure and problems of the heart. However, I am unaware of the truth that though acnesol contains erythromycin, its purpose is that of an antibiotic or not? Should I continue using acnesol?
A:Erythromycin containing gels/lotions have very little systemic absorbtion. Hence, the only side effects, usually encountered are topical (dryness/irritation).
