Can You Take Ciprofloxacin and Melatonin Together?
No documented interaction was identified between ciprofloxacin and melatonin in the sources reviewed.
What the interaction means
Ciprofloxacin's FDA label's only "melatonin" hit is "MELATONIN RECEPTOR AGONIST" inside its generic pharmacologic-class taxonomy dropdown, not a prose interaction statement. NCCIH's melatonin page does not mention ciprofloxacin/quinolones/antibiotics.
No documented interaction 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
Both substances' own current authoritative sources were checked directly, full text, in both directions; the taxonomy-list mention was deliberately not treated as a real interaction claim.
