Your Side Effects May IncludeCipro side effects
ciprofloxacin
This side effect is printed on the FDA label for Cipro. It was a question in our daily quiz, where you pick the real side effect from four choices.
A torn Achilles tendon
It's a boxed warning, the FDA's strongest. Tendons can tear months after the last pill.
“Tendinitis or tendon rupture can occur, within hours or days of starting CIPRO, or as long as several months after completion of fluoroquinolone therapy.”
Stop and call your doctor at the first sign of tendon pain or swelling. The risk is higher if you're over 60 or take steroids.
1,309 reports to the FDA's adverse event system mention a torn tendon. A report is not proof the drug caused it. See the query
