[Ciprofloxacin-associated bilateral acute achilles tendinitis].

Bilateral achilles tendinitis developed in a 40-year-old man following treatment with Ciprofloxacin, 500 mg twice a day, for prostatis. The signs of tendinitis resolved 6 weeks after cessation of the drug. In recent years very few cases of this rare complication have been reported. In some cases it results in a torn achilles tendon. If diagnosed early, complete recovery usually follows about 6 weeks after cessation of the drug.
