19 year old female prescribed levaquin for a kidney infection after a round with cipro did not cure a UTI. Symptoms gradual at first but began with chest pain a couple of days into treatment. The doctor said it was costochondritis which sometimes comes on during infections and was not serious. He told her to continue the medications (this was not her regular doctor...he had closed for the day so she was seen at the after hours clinic). Other symptoms include: Headache (drinks plenty of water), muscle aches and pain, dry mouth and throat, nausea, dizziness, loss of appetite. When the chest pain spread across the front of the chest and into her back and she had experienced swelling around the eyes and in face that same day we went to the emergency room. After many tests, this doctor said it was the levaquin and told us it had been black boxed. He said they had been told in the ER to immediately take anyone on levaquin off of it if they came in experiencing pain or other symptoms. He said she should be better in a few days. He shared that he too had similar problems when he took it and thought it was going to kill him. When Monday gets here we will make a return visit to her family doctor to follow up on all of this. After reading all these other people with the same or similar symptoms, I am worrying and I am praying that she will not continue to have trouble. We hope all of you are better soon. Please don't take this drug again!!!!!!
