A podcast listeners wrote in and she asked, 

"How long do I need to stop running or take it easy after taking five doses, meaning two and a half days, of Cipro? 

I told my doctor I was a runner, so I didn't trust their opinion on when or how I should run. 

I haven't run since finding out the side effects two weeks ago, and the Achilles feels weak and a little thicker than the other side."

This is a great question, and she is right to be concerned because the FDA issued a black box warning because of an association between Cirpo antibiotics and Achilles tendon ruptures.

Today on the Doc on the Run podcast, we're talking about a runner with Achilles tendon worries after taking Cipro antibiotics.
