Doxycycline
bronchitis
"I used doxycycline hyclate for my bronchitis. It really helped me get better faster, it even got rid of the few zits I had. The downfall is after I was done with my prescription I broke out all over! My face, neck, and chest are all covered in acne or its a rash, I'm not sure... I've never had bumps this bad in my entire life!"
