Minocycline
"I have used this medication successfully for years. Initially I used it daily for a few weeks, then tapered down to 3 times a weeks, then only 3 days in a row for flare ups. I haven't used any for 3 years until just recently when I had a flare up. After one dose the redness decreased and no new pustules. The only side effect has been yeast infection when I take higher doses, i.e., twice a day for 5-7 days, but I have not found that I need to do that. I can usually take 50 mg, once a day for 3 days, then I take a dose every other day for 3 days. By then the pustules have resolved and no yeast infection."
