Began taking doxy 6 days ago for infected cut on my face. It worked great on the infection. However, the side effects are killing me. The first 3 days I had sore areas in my mouth, tongue, and one side of my throat, as well as congestion and cold-like symptoms. These are all listed as side effects. Also listed are stomach upset, diarrhea, and muscle aches, which I've had as well. It seems to make my GERD a little worse, but I'm careful not to lie down for an hour after taking it. While the mouth & throat pain has cleared, the muscle aches are nearly unbearable. About 2 hours after taking the doxy I am almost floored with fatigue. At the same time diarrhea starts and menstrual spotting starts as well. On top of all that I'm finding myself more anxious, depressed, and physically exhausted. It's overwhelming. My husband took doxy a month ago for epididymitis. He had serious mood issues, upset stomach, and sensitivity to heat as well as sun. He took his pills with food (he wasn't told not to) so his side effects were less severe, but I suspect it's because he wasn't absorbing as much of the medication.
