Question: I am an athletic 50-year-old man and I’ve been suffering from tendonitis in my bicep. It’s been three months and it isn’t getting better. I took Levaquin for a prostate infection recently. Could this be the cause?

Dr. Hibberd’s answer:

Bicipital tendonitis is not that uncommon. It’s hard to tell if Levaquin — a quinolone antibiotic — could be the cause of your tendonitis. Despite the widespread publicity of tendon problems from Levaquin, I have yet to see one case of bicipital tendonitis from quinolone antibiotic use. I recommend that you seek specialty consultation from an orthopedic specialist to help answer your question. An MRI should be able to differentiate between a tendon injury and a drug-induced tendon problem.
