Does Tetracycline Work?

Hello,
I went to the doc today, because I have problems with acne. He prescribed me with tetracycline, but I am a little suspicious if that would help. Has anyone any experience with tetracycline?

Hey there,
Tetracycline is an antibiotic that kills bacteria on the skin. Tetracycline helped me… and I had ulcers (ulcers are really big, awful and painful acne). I think you should try tetracycline. Oh, yes, one more thing I wanted to remind you… do not squeeze acne, this makes situation worse and in that case even tetracycline doesn’t help.
