See the full CoQ10 (Coenzyme Q10) page and Losartan page for other reviewed interactions and reference information.

What the interaction means

Losartan's FDA label does not mention coenzyme Q10. NCCIH's CoQ10 fact sheet does not mention losartan, ARBs, or angiotensin; it notes only that CoQ10 'probably doesn't have a meaningful effect on blood pressure' generally.

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.

What the sources say
