My father was prescribed Levaquin 750mg as a 5 day dose. They call it a Levapak. After the first couple of days he began having restlessness, headache, and the scariest of all, emotional distress and fear of death. He would start crying for no apparent reason. This is a normally emotionally strong man who has been reduced to tears by this medication. He couldn't sleep because of the restlessness. He had, like one of the others here, feelings of futility. It didn't occur to us that it could be the Levaquin until we found this website. He only had one day's dose left by this time, but he is not going to finish it. We only wish we had found out sooner. He would have quit taking it immediately. His Pharmacist told us that he should stop taking it also and put a note in his file to never fill this prescription for him again. Even the Pharmacist said that he has heard of this happening and that this drug should be off the market. I just hope others who find this website can take some solice in knowing that you're not going crazy.
