OBJECTIVE: To describe a case of levofloxacin-induced partial Achilles tendon rupture; this occurred in the presence of known risk factors and acute renal failure. CASE SUMMARY: A 79-year-old white man received levofloxacin for presumed pneumonia, developed acute renal failure in the setting of dehydration, and began having ankle pain on the 12th day of admission. Levofloxacin was discontinued, and magnetic resonance imaging revealed a 6-cm partial tear and degenerative changes. DISCUSSION: The Naranjo probability scale indicates a possible association between levofloxacin and tendon rupture because the event occurred in the setting of known risk factors such as steroid use, renal failure, older age, and male gender. CONCLUSIONS: Levofloxacin, like other fluoroquinolones, may cause Achilles tendon rupture, and this may be particularly likely with known risk factors.
