Poison ivy patch symptoms and conditions

I took 4 of the 10, 500 mg daily dose of Levaquin that was prescribed to me. My heart rate was so fast that I thought I was going to have a heart attack! And now I have this awful rash all over my body. It's been 4 days since I 've had the last dose and it's not getting better. Does anyone have any idea when this itchy rash will go away?

I was on Levaqin for a week (500 mg) for bronchitis. It seemed to work and I didn't notice any side effects and I am usually sensitive to antibiiotics (dizziness, etc..). However, the day after I finished my last dose I developed an itchy rash on my outer thighs, my back, my underarms and a few other random places. I also now have a yeast infection which I guess is a common side effect. The rash is what concerns me. At first I thought it wouldn't be related because it came on after I finished the antiobitcs but after reading some of these posts I see that you can get rash after taking the medication. Has anyone else had a rash AFTER taking Levaquin?
