If you feel as though your current med is not working for you, as this happens pretty frequently, you might want to ask your derm if he can switch meds on you... Tetracycline no longer works on me, and a lot of the others dont as well... Ask about Adoxa which has worked pretty well, although everyone responds differently to different things, but see about a switch... It can and usually does take a month or more to see any kind of improvement, but it's well worth the shot... GOOD LUCK
