Question: Keflex- possible tendon damage like Cipro?

 Llewellyn - Thu Mar 26, 2009 3:12 pm

My husband was recently prescribed Keflex for a skin infection. He had heard that another antibiotic, Cipro, possibly caused tendon or ligament rupture and was wondering if Keflex possibly had some of these same drawbacks. Playing basketball is his #1 stress reliever during these difficult times and he is really concerned about taking any antibiotic since he is already nursing a chronically sore achilles tendon (which he stretches religiously) and also has a small tear in his rotator cuff. He is hoping that Keflex does not have any of the potential rupture drawbacks as Cipro, but is not sure.

Any information with regard to this issue would be greatly appreciated. Thank you.

Hello, Llewellyn,

The identified potential side effects of Keflex do not include the risk of tendon damage. There should be information about Keflex included with your prescription. If the pharmacist did not include that information, don't hesitate to return to the pharmacy and request a package insert. The identified musculoskeletal possibilities (low possibility) are arthritis, arthralgia, and joint pain.

I hope this helps your husband continue with his lifestyle and stress relief.
