I was prescribed Levaquin about 3 weeks ago for a possible sinius infection. I was reading the booklet that comes with the meds and saw some of the side effects, tendon rupture, dizziness, sleep issues, etc. I told the doctor I didn't want to take it because I already have some tendinitis in my shoulder and other aches and pains. He said okay, then went back to the doctor for follow up and said either take the med or lets do a CAT scan on my sinius's. I said okay I will take it and see what happens... Well It was 500 mg and I took it for only 4 days out of the 10 and my pains were worse. I can not sleep at night and have been getting very dizzy. I called the doctor and told him, and he didn't seem fazed by what I told him and said just to stop taking and prescribed another antibiotic. I have been off the med for 3 days now and I still can not sleep and still feel dizzy. How long is this going to last? I go to a hematologist and two days ago told her about the med and she too said she can not take this med, it is very strong and she had the same feelings. Has anyone been off this med, and for how long did the dizziness go away. I have two young kids and they both just got the stomach bug, and I'm so overtired and just want to sleep but I can not.
