What the interaction means

Folate's NIH ODS fact sheets name five interacting medications -- methotrexate, phenytoin, carbamazepine, valproate, and sulfasalazine -- and doxycycline is not among them. Doxycycline's FDA label does not mention folate or folic acid.

No documented interaction between Doxycycline and Folate / Folic Acid 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

Folate's NIH ODS fact sheets and doxycycline's FDA label were checked directly, full text, in both directions. Folate's own named interacting medications do not include doxycycline or other antibiotics.
