i went to the dr today just for a regular check up and i told her i was concerned about my acne. i started clindamycin topical in 1998 til 2002 when i got immuned to it because it stopped working, and she put me on erthromycin topical 2% today. i wanted to know has anyone had any experience w/ this? she said it was kinda like the clindamycin but a different antibiotic. clindamycin had my face ZIT FREE for 4 years so i'm hoping this will work...any imput?
