Summary

Concurrent NSAID and fluoroquinolone use may lower the seizure threshold and cause CNS stimulation. Seizures are uncommon, but the risk is greater in patients with epilepsy, prior CNS disease, renal impairment or high fluoroquinolone exposure.

What this interaction means in plain words

Gemifloxacin and Naproxen 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.

Gemifloxacin belongs to Anti Bacterial; Naproxen belongs to Musculoskeletal.

Evidence level: Low

Why it happens

Fluoroquinolones antagonize GABA-A receptors, and NSAIDs may potentiate this effect; the mechanism is incompletely characterized.

What to do

Avoid the combination in patients with seizure disorders or other CNS risk factors, or choose a different antibiotic. Otherwise counsel patients to report tremor, confusion or seizure activity and adjust the fluoroquinolone dose for renal function.

What to ask your pharmacist

  • Should I take them at different times of day?
