A case control study 1 assessed the risk of Achilles tendinitis and Achilles tendon rupture in users of fluoroquinolones. The cases were 46 776 users of fluoroquinolones. Current exposure to fluoroquinolones increased the risk of Achilles tendon disorders. The adverse effects were rare; the overall excess risk was 3.2 cases per 1 000 patient years. The effects seemed to be restricted to people aged 60 and over. Concomitant use of corticosteroids increased the risk substantially.
