Summary

NSAIDs may enhance the seizure-provoking potential of fluoroquinolones. Case reports describe convulsions when the two are combined, especially at high doses or in patients with CNS disease or renal impairment.

What this interaction means in plain words

Ciprofloxacin and Indomethacin 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.

Ciprofloxacin belongs to Anti Bacterial; Indomethacin belongs to Musculoskeletal.

Evidence level: Low

Why it happens

Fluoroquinolones antagonize GABA-A receptors, and NSAIDs may potentiate this effect; the mechanism is not fully established.

What to do

Avoid the combination in patients with a seizure history or other risk factors and use the lowest effective ciprofloxacin dose; counsel patients to report tremor, confusion or seizures.

What to ask your pharmacist
