Fluoroquinolone antibiotics are used to treat a wide range of infections and as prophylaxis against infection in certain immune compromised patients. In 2008 the FDA issued a boxed warning for tendonitis and tendon rupture for the fluoroquinolone antibiotic class, and in May 2016 a statement recommending the use of alternate therapies for uncomplicated UTIs and upper respiratory infections was issued. The mechanism by which fluoroquinolones causes tendon injury has not been elucidated, but may be related to oxidative stress caused by the overproduction of reactive oxygen species in tenocytes.
Adverse event reporting to the FDA is performed voluntarily by healthcare professionals and consumers through MedWatch. An analysis of tendon rupture events associated with fluoroquinolone use reported to the FDA’s Adverse Event Reporting System (FAERS) database was recently published.
