Summary
Fluoroquinolones and systemic corticosteroids each raise the risk of tendinopathy, and using them together increases the chance of tendon inflammation or rupture. With topical dexamethasone-tobramycin systemic exposure is low, so risk is smaller.
What this interaction means in plain words
Dexamethasone-tobramycin and Ofloxacin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dexamethasone-tobramycin belongs to Anti Bacterial; Ofloxacin belongs to Anti Bacterial.
Why it happens
Additive pharmacodynamic tendon toxicity from fluoroquinolone-related tenocyte injury and corticosteroid-induced tendon weakening.
What to do
Counsel the patient to stop ofloxacin and rest the limb if tendon pain or swelling develops. Prefer a non-fluoroquinolone antibiotic in older patients or those on prolonged systemic steroids.
