See the full Doxycycline page and Potassium page for other reviewed interactions and reference information.
What the interaction means
Doxycycline's documented interactions are mineral-chelation-focused (calcium, magnesium, iron, aluminum, bismuth subsalicylate) -- potassium is not among them. Potassium's own fact sheet does not mention doxycycline.
No documented interaction between Doxycycline and Potassium 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 Doxycycline's and Potassium's own current authoritative sources were checked, in both directions.
