I had taken tetracycline before. The side effects were terrible. For years I suffered from PAINFUL red spots behind my ears which took so long to get cured. Now and then I still have them.

I've been taking tetracycline since for 6 weeks now..before I took it, I had very bad red and painful cystic pimples, i take 250 mg 2x/day. so far i dont get anymore painful cystic pimples though only small ones..it's working for me so far but not fast though...im planning to take it for 2 mos..and stop and undergo professional microdemabrasion...hope this would help..:)
