Which fluoroquinolone is particularly noted for the risk of tendon rupture?

Levofloxacin is especially noted for the increased risk of tendon rupture, particularly in certain populations. The fluoroquinolone class of antibiotics, which includes levofloxacin, has been associated with increased incidence of tendon damage, most commonly affecting the Achilles tendon. This risk is heightened in patients over 60 years of age, those who are concurrently taking corticosteroids, and individuals with existing renal insufficiency.

The mechanism behind this adverse effect is not entirely understood, but it is believed to be related to fluoroquinolones’ ability to induce oxidative stress within tendon cells and disrupt collagen synthesis. Among the fluoroquinolones, levofloxacin has been highlighted in clinical studies and safety warnings for this particular risk, leading to caution in its prescribing for appropriate patients.

Understanding this risk is crucial for healthcare providers to ensure proper patient counseling, especially for individuals at higher risk of tendon injury, thus ensuring the benefits of antibiotic therapy outweigh the potential hazards.
