acne
"I'm 14 years old, and my dermatologist prescribed Doryx for me for 2 months and all it did was create worse acne. I have no idea why it didn't work, but I was put on Sulfamethoxazole about a week ago, and I already see a difference. My dermatologist said this drug is almost the same as Doryx, but has a different molecule in it. If you are going to try Doryx, I would definitely take it with food. With Doryx I threw up 4 times because I didn't take it with enough food."
