Summary
Fluoroquinolones such as ofloxacin can cause tendinitis and tendon rupture, and concurrent systemic corticosteroids markedly increase this risk. Older age and renal impairment add to the risk.
What this interaction means in plain words
Ofloxacin and Prednisone can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Ofloxacin belongs to Anti Bacterial; Prednisone belongs to Endocrine.
Why it happens
Additive tendon toxicity through impaired collagen turnover and tenocyte damage.
What to do
Prefer a non-fluoroquinolone antibiotic in patients on prednisone, particularly older adults. If used, instruct patients to stop ofloxacin and rest at first tendon pain.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
