What the interaction means

Losartan's FDA label documents four drug-interaction categories -- potassium-raising drugs, lithium, NSAIDs, and dual RAS blockade with other ARBs/ACE inhibitors -- and ciprofloxacin or quinolone antibiotics are not among them. Ciprofloxacin's own FDA label does not mention losartan, ARBs, or angiotensin.

No documented interaction between Ciprofloxacin and Losartan was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

Losartan's FDA label and ciprofloxacin's FDA label were checked directly, full text, in both directions. Losartan's own named interaction categories do not include antibiotics.
