I was prescribed Levaquin (500mg x 10 days) for bronchitis and ear infection. I'd already taken heavy regimen of Augmentin a few weeks prior, but my symptoms only abated temporarily and then returned 'full force'. My case is a little different from the typical poster, as I was not ignorant of the possible nasty s/e of this drug. In fact, when the Levoquan was first prescribed for me, I read this message board (among others) and was scared enough by what I read that didn't start this medication right away. I went back to my MD to discuss my concerns; he acknowledged that some people do experience some bad side effects from this drug but indicated that these effects tend be pretty rare and didn't think I would have a problem - given my age (32) and otherwise good health. After waiting a few days and debating whether to try this medicine, my upper respiratory infection worsened and my ear pain became so tormenting that I finally decided it was worth the risk to at least try Levaquin...hoping I'd be one of the lucky one who experienced few, if any, side effects. After taking the first pill yesterday, everything seemed fine for several hours. In fact, I almost immediately noticed improvement of my URI and ear ache. However, last night before bed I noticed that both of my knees felt swollen and walking felt uncomfortable. I also noticed an audible "clicking" sound in my knee joint when using stairs. Today, I called my MD to report my symptoms. My doctors nurse called me back and suggested I not taking any more doese until she was able to discuss this matter with the doctore (who was out of the office but due to return tomorrow). By the time the nurse gave this advise, I'd already taken the second dose of Levaquil earlier in the day. Tonight, my knee pain (especially right) is much worse and it hurts to get up and walk around. I'm starting to feel like an old man. I've never had any joint problems or tendonitis prior to taking this medication. Tomorrow I intend to ask my doctor for advice. I don't plan on taking any more of this medication. I do fee a little conflicted though, because now after taking the second dose of Levaquin, my upper respiratory infection seems almost gone and my ears have completely stopped aching. If anyone has any suggestions, it would be appreciated. Should I expect that my knee pain will resolve in a few days after stopping this med? Again, I'm a health 32 year old male, and hope that this drug hasn't done anything irreperable (sp?). Thanks for listening.
