Levofloxacin-induced tendinopathy of the hip
Abstract
OBJECTIVE: To describe what we believe to be the first reported possible case of tendinopathy of the hip in a patient receiving levofloxacin.
CASE SUMMARY: A 58-year-old male with recurrent otitis media was admitted for left lateral hip pain of 10 on a scale of 10. He had started a 5-day course of levofloxacin 750 mg/day 10 days before he began experiencing pain. He also took simvastatin 20 mg/day and walked 90 minutes each day. He was treated with oxycodone with acetaminophen and physical therapy. His pain had improved significantly at a 10-day recheck.
DISCUSSION: Fluoroquinolone-induced tendinopathy has been well-reported in the literature, but most cases involve pefloxacin and affect the Achilles tendon. Only 11 cases of tendinopathy have been reported with levofloxacin based on a MEDLINE search (1966-December 2011). This is the first known case reported that involved tendinopathy of the hip believed to be caused by fluoroquinolones. The Naranjo probability scale revealed a possible adverse reaction of levofloxacin-induced tendinopathy of the hip. Contributing factors likely included the high dose of levofloxacin, concomitant use of a statin, and strenuous physical activity.
CONCLUSIONS: Health care professionals should be aware of the possibility of tendinopathy of the hip in patients who receive fluoroquinolones. Thorough history for possible risk factors should be obtained. Patients on fluoroquinolones at risk for tendinopathy should be counseled to avoid strenuous…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
