I was prescribed Levaquin 500 for possibility of a low grade infection (101 temp). Within two days I started feeling anxious, unable to sleep, sweating, dizziness, severe pain in both knees and elbows - could not walk. Upset stomachnausea even though I followed instructions to drink a lot of water. Then flashing began in my eyes. I stopped taking the pills after the third day. The other symptoms began to stop. However the flashing in my eyes continued only to be replaced with big black floaters which, I understand, are permanent. I had NOT received any warnings from the doctor or the pharmacist other than to "take with a lot of water".
