Can You Take Doxycycline and Melatonin Together?

No documented interaction was identified between doxycycline and melatonin in the sources reviewed.

No documented interaction identifiedEvidence: Moderate

What the interaction means

Doxycycline's FDA label's only "melatonin" hit is inside its generic pharmacologic-class taxonomy dropdown, not a prose interaction statement. NCCIH's melatonin page does not mention doxycycline.

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.
