http://www.medications.com/effect/view/28783 I have been on Levaquin over 6 times in the past 2 years for upper respiratory infections. I just came off another levapak 750mg for 10 days and my biceps were feeling really tight. I mentioned this to my doctor but he said it was a common side effect.

It is very simple and only takes a couple of minutes. You will find it here: http://www.fda.gov/medwatch/how.htm I just filled out one for my distal bicep tendon ruptu http://www.medications.com/effect/view/28783?item=6243 Sun, 30 Mar 2008 19:31:25 -0400 http://www.medications.com/effect/view/28783?item=6250 I'm so sorry for you. I've been affected by this poison as well. Go to www.fqvictims.org and www.fqresearch.org and you'll find some help and also some information that you can print out and give to your "intelligent" dr. I guess he can't read. Make sure http://www.medications.com/effect/view/28783?item=6250
