Fluoroquinolones are antimicrobial agents that inhibit bacterial DNA synthesis by binding to DNA gyrase and DNA topoisomerase IV. Fluoroquinolones have also been associated with the development of tendinopathy, tendon rupture, and arthropathy. The postulated mechanisms for quinolone-associated tendinopathy are alteration of the tendon extracellular matrix, impairment of tenocyte proliferation, and enhanced apoptosis due to the quinolone cation chelation properties. We present a case of a man who developed multiple tears of the rotator cuff after exposure to levofloxacin. Although marketed quinolones are well tolerated, adverse events involving gastrointestinal, cardiovascular, neurological, and tendinopathy and at-risk patient populations should be kept in mind by clinicians.
