Results from these studies suggest that individuals exposed to fluoroquinolones are at increased risk for Achilles tendon rupture, particularly within the first month following exposure to the drug (odds ratios ranged from 1.1 to 7.1). One study showed an increased risk of tendon rupture in those over 60 years of age.
Why does fluoroquinolones cause tendon rupture?
Fluoroquinolones have been hypothesized to compromise tendon function and increase risk of injury, especially in weight-bearing joints most subject to mechanical force,8 via several possible mechanisms. These medications may cause direct tissue injury, including necrosis or exposure-dependent cellular apoptosis.
How do fluoroquinolones affect tendons?
The most common presenting symptom of fluoroquinolone-associated tendinopathy is pain. This pain is usually of a sudden onset and may be accompanied by acute signs of inflammation and swelling. Achilles tendon rupture may be preceded by pain,25,26 but half of tendon ruptures have been reported to occur without warning.
Do all fluoroquinolones cause tendon rupture?
“In our study, fluoroquinolones as a class were not associated with the increased risk of tendon ruptures,” the researchers point out. “Neither ciprofloxacin nor moxifloxacin exhibited any risk for tendon ruptures.
Is tendon damage from Cipro permanent?
Fluoroquinolone medicines (which contain ciprofloxacin, levofloxacin, lomefloxacin, moxifloxacin, norfloxacin, ofloxacin, pefloxacin, prulifloxacin and rufloxacin) can cause long-lasting, disabling and potentially permanent side effects involving tendons, muscles, joints and the nervous system.
