Summary

Fluoroquinolones can cause tendinopathy and tendon rupture, and concurrent systemic corticosteroids further increase this risk. The risk is greatest in older patients and those on prolonged steroid courses.

What this interaction means in plain words

Hydrocortisone and Norfloxacin 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.

Hydrocortisone belongs to Endocrine; Norfloxacin belongs to Anti Bacterial.

Evidence level: High

Why it happens

Additive tendon toxicity from fluoroquinolone and corticosteroid effects on tenocytes and collagen.

What to do

Prefer a non-quinolone antibiotic where feasible, particularly in older patients. Stop the quinolone and avoid exercise at the first sign of tendon pain.
