Fluoroquinolone antibiotics have widespread usage for treatment of Gram-negative-related infections particularly urinary tract and respiratory infections. Due to the prevalent usage of this family of antibiotics, it is necessary to be careful about their side effects including Achilles tendinitis, which can ensue tendon rupture. This case report introduces an 84-year-old man diagnosed with Achilles tendinitis due to consumption of ciprofloxacin for treatment of urethritis. The patient experienced pain on posterior region of the left ankle after three days of antibiotic therapy onset and the pain was alleviated within a week following ciprofloxacin cessation along with treatment with nonsteroidal anti-inflammatory drugs. The Naranjo score was determined seven for this patient; accordingly, ciprofloxacin was the probable cause of this reaction. Early diagnosis of fluoroquinolones-associated Achilles tendinitis and stopping the treatment may prevent tendon rupture. M3 ER -
