Doxycycline
rosacea
"Doxycycline worked very well- and very quickly for me. I noticed results within a week and after using it for a few weeks- my skin was completely cleared up! Good deal, right? Not quite! I continued to take this medication for over a year. Suddenly I began to have a HACKING COUGH immediately followed by vomiting. (Coughing so hard I would vomit.) I couldn't figure it out. I began to get very sick. Couldn't eat and then couldn't even function on a daily basis. I became so sick, in fact, that I was hospitalized. I was taken off the medication and voila!- the "draining" in my throat subsided, the cough stopped, the vomiting stopped. So BE CAUTIOUS!"
