Hi !
I took doxycycline for fever. My doctor prescribed 100mg twice a day for 7 days. I took for a day and half and I started experiencing cramps in upper stomach. I could not bear the feeling. I called the doctor and explained to her my symptoms. She asked to get off it immediately. I have stopped doxycycline. It has been one full day since I stopped it but I am having diarrhea and cramps haven't gone either. I don't know when it will completely go away. The funny part is the fever left me and I know it wasn't these tabs that made me feel better but doxycycline has given me other problems to worry about now!!
