A patient comes to the ER having injured his lower leg in a soccer match. Tests reveal a tendon rupture with tendonitis. Which of the following antibiotics, if required, would most probably NOT be given to this patient?

A. Ceftriaxone [Rocephin]: Ceftriaxone is a broad-spectrum cephalosporin often used to treat a variety of bacterial infections. It is generally safe for musculoskeletal infections and does not carry a significant risk of tendon injury, making it appropriate if an antibiotic is indicated for prophylaxis or treatment of secondary infection in soft tissue injuries. B. Clarithromycin [Biaxin]: Clarithromycin is a macrolide antibiotic effective against gram-positive and some gram-negative bacteria. It is commonly used when penicillin allergy exists and does not have an association with tendon toxicity. It may be considered for soft tissue infections if indicated. C. Amoxicillin/Clavulanate [Augmentin]: Amoxicillin combined with clavulanate is frequently used for bite wounds, soft tissue injuries, and infections caused by skin flora. It has a broad antibacterial spectrum and is safe for musculoskeletal injuries, including tendon and tendon sheath involvement. D. Ciprofloxacin [Cipro]: Ciprofloxacin is a fluoroquinolone antibiotic known to increase the risk of tendinopathy and tendon rupture, particularly in the Achilles tendon and in patients with musculoskeletal injuries. Because this patient already has a tendon rupture and tendonitis, ciprofloxacin would be avoided to prevent exacerbation of tendon damage.
