I started taking Levaquin for strep throat. I am 22 years old and it good health. I was supposed to take it for 5 days. During the 5 days my stomach felt a bit uneasy, but I was expecting that because i usually have a small stomach ache when taking anti-biotic. On the fourth day i ended up bed ridden. I woke up with severe diarrhea, and threw up. I attempted to go to work, but my symptoms got worse. I ended up in bed with severe stomach and body pain for the rest of the day not able to move or hold anything down. If i tried to drink or eat anything i either threw it up or had diarrhea. It was worse than the flu. I then looked up side effects of Levaquin and found the following: feeling restless or anxious; nausea, vomiting, diarrhea, stomach pain; headache, drowsiness, dizziness;sleep problems (insomnia). I fell under each of those categories. This drug is evil. They said keep taking it but consult with your Dr... yea right. I was DONE with it. I'd rather get strep again than go through that again! DON'T TAKE LEVAQUIN!
