Give it two weeks.: Acne lesions that are open are tissue wounds, and the erythema and swelling take some time to go down, giving successful rx a "lag time, " which makes it seem the med is not working. Minocycline and Doxycycline are alternates, but i couple them with a bezoyl peroxide scrub used topically.
