  • Achilles tendinitis or rupture is among the most serious side effects associated with FQ use
  • The large body of data provided by clinical reports, histopathological examination, and experimental studies provides cogent evidence supporting a direct link between FQ use and tendonitis/tendon rupture
  • Risk factors associated with FQ-induced tendon disorders include age greater than 60 years, corticosteroid therapy, renal failure, diabetes mellitus, and a history of musculoskeletal disorders

  • The average age of FQ-induced tendinopathy is 64 years, with a male-to-female ratio of 2:1, and a 27-percent incidence of bilateral involvement
  • Although more than 95 percent of cases of tendinitis/rupture secondary to FQ involve the Achilles tendon, other reported sites of tendon involvement include the quadriceps, peroneus brevis, and rotator cuff
  • FQs demonstrate a 3.8-fold greater risk for development of Achilles tendinitis/rupture
  • a large population-based case control analysis, patients treated with FQs exhibited a substantially increased risk of developing tendon disorders overall (1.7-fold), tendon rupture (1.3-fold), and ATR (4.1-fold)
  • patients taking FQs with concurrent exposure to corticosteroids were found to experience a compounding effect on the risk of tendon rupture, specifically a 46-fold greater predisposition
  • Some authors have recommended that patients with a history of Achilles tendinitis and advanced age should not be prescribed FQ antibiotics
  • Approximately 50 percent of patients will recover within 30 days, with 25 percent of patients having symptoms persistent for longer than two months
  • The mean latency period between the start of FQ treatment and occurrence of tendinopathy has been reported to be a few hours to months, with a median onset of 6 days
  • The exact pathophysiology of FQ-induced tendinopathy remains elusive
  • it is possible that FQs have a direct cytotoxic effect on enzymes found in mammalian musculoskeletal tissue
  • It has been theorized that FQs disproportionately affect human tendons that have a limited capacity for repair, such as in older patients or structural compromise (i.e., pre-existing tendinopathy or trauma)
  • histopathological findings are similar to those observed in overuse conditions in athletes
  • Treatment with a FQ should be discontinued and physical therapy initiated
  • treatment should include rest and decreasing the physical load on the tendon.
  • Approximately 85 percent of patients present in less than one month
  • Because rupture can occur even late in the course of treatment or after discontinuation of FQ use, patients receiving a FQ should be counseled to seek medical attention immediately if symptoms, such as redness, pain, swelling, and stiffness, develop
  • FQs should be used cautiously in patients with risk factors associated with tendinitis, such as advanced age, history of tendon rupture, corticosteroid use, and/or acute or chronic renal dysfunction

    Great review of the link between flouroquinolones and Tendinitis and Tendon rupture.  Yes, there is a direct link.
