"unfortunately i have suffered with acne since primary school. that was the start of my acne, but then got worse all through secondary school. because i went years and years with very clogged skin, and very nasty acne both black heads, white heads and angry pussy spots i never thought i would be able to clear my skin up. i was then prescribed oxcytetracyclin i think how it&#039;s spelt ?, and these where amazing they cleared my skin up down to a t. fast forward 2 years now, my body has got used to them and it was on to trimethoprim to try and clear the breakouts. these are amazing i saw results in 2 days however i had to stop as i started to get vomiting, nausea, headaches the list goes on. these are great tablets but side effects are terrible."
