Acne
"I started taking Doxycycline because I was in a Malaria country, and it was required. My doctor there said that it would also help with my mid-severe cystic acne, and it totally did.

I am back in the States now, after 4 months of being abroad, and am still taking Doxy for my skin. 

For those of you experiencing an upset stomach, eat BEFORE you take it, and stay upright for a half hour after. If you don&#039;t eat before, you will throw up. And it needs to be substantial,  not just a cracker."
