My mom took Levaquin for a sinus infection and within three days of starting the medicine her kidneys began to fail. Her heart rate and blood pressure were elevated. After 6 months of going to doctor after doctor, she was diagnosed with chronic kidney disease and high blood pressure. Now she is on dialysis three times a week. The kicker...she had just had a complete physical with a blood work up three weeks prior to taking Levaquin and she was absolutely fine. Now, she's dying of chronic kidney disease.
