Can You Take Ashwagandha and Losartan Together?

Ashwagandha is named by NCCIH as a supplement that may interact with high blood pressure medications, of which losartan is one.

MonitorEvidence: Moderate

See the full Ashwagandha page and Losartan page for other reviewed interactions and reference information.

What the interaction means

NCCIH's ashwagandha fact sheet states: "There is evidence that ashwagandha might interact with some medications, including those for diabetes and high blood pressure..." Losartan's own FDA label describes it as "an angiotensin II receptor blocker (ARB)" indicated for hypertension. NCCIH does not name losartan specifically or describe the mechanism beyond this class-level statement.

Why it may happen

Not further specified by NCCIH beyond classifying high blood pressure medications generally as a class ashwagandha might interact with; ashwagandha has been studied for potential blood-pressure-lowering effects of its own, which could compound with an antihypertensive like losartan.

Practical context

This is a class-level finding, not a losartan-specific one -- NCCIH does not give a spacing interval or dose-adjustment instruction, and losartan's own label does not separately name ashwagandha. Anyone taking losartan who is considering ashwagandha should discuss it with their prescriber and monitor blood pressure for an additive lowering effect.
