I was prescribed Biaxin XL 4 days ago for sinus infection ( 2 -500mg tablets taken together once per day). The side effects were worse than the infection for me. I became extremely anxious and panicky, nauseated, sweaty, tired but unable to sleep and I lost my sense of smell and had a terrible metallic taste in my mouth. By the third day, I could tell the infection seemed a little better, but then I took my third dose and within 30 minutes I got the shakes, suffered diarrhea with terrible stomach cramps, vision problems, loss of appetite and a terrible anxiety/panic attack where I felt that I was losing it. I had to leave work to get home quickly. My blood pressure kept going higher and higher and I started to get teary. This was one of the worst days of my life. I have stopped taking this medication and have replaced it with amoxicillin. Today I feel much better and blood pressure has gone down. I will never take Biaxin again. Continuing on this medication for 10 days could have led me to suicide. If you feel these things when taking any medication, stop taking it right away and speak with your doctor and pharmacist. When I contacted my doctor;s office they said it should not make me feel anxious. They should obviously do more research on the drugs that they prescribe. I hope no one else experiences these terrible side effects.
