I took doxycycline for a little acne on my back I would get when I worked out. I am a fit healthy man of 48 years. People tell me I look late twenties early thirties. I have to tell you all my experience with this antibiotic has been a nightmare for me. Stomach queasiness, severe stomach pain, dizziness, headaches, lower back pain, from no acne on face to small blisters and acne. Depression and panic attacks. I went to my doctor and demanded my blood get checked for everything from STD's to HIV. Everything came back negative and no answers other than I had a severe allergic reaction to the medication. I took this medication for a month twice a day. I have been off for two months now and I am just now feeling better I can eat without feeling stomach queasiness. My face is getting better but still hoping it will return to normal. I started taking Primadophlius and Ester-c to help build my immune system. I haven't exercise yet because I am afraid to weaken my body. This drug really scared me. I sincerely hope all of you get better:-)
