Acne
"I had severe acne as a teenager and Doxycycline did not have an effect. I ended up taking Roaccutane which eventually left me with clear skin for 8 years. However, the last 9 months I have had a reoccurrence of moderate acne and was prescribed Doxycycline. I was convinced it would have no effect again but within 3 days I saw an improvement. Now after 2 weeks I have had no new spots. The first few days it made me feel really nauseous but more bearable if I take it with a meal and lots of water."
