Beet and Hydralazine

Here is the interaction we found between these two, with the evidence behind it.

Minor

Antihypertensive Drugs

Why this applies to Hydralazine

Hydralazine falls under Antihypertensive Drugs — the group Beet interacts with.

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.
Severity Minor Likelihood Possible Evidence A

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both beets and hydralazine work to widen your blood vessels. Hydralazine relaxes vessel walls directly, while beets give you nitrate that your body turns into nitric oxide, which also helps vessels open up. Stack the two and, in theory, your blood pressure could dip a little more than expected. If that happens, you might notice lightheadedness, a flushed face, headache, or a fast or pounding heartbeat when you stand up.

The good news is the evidence points to a small, short-lived effect, and some studies showed no real change at all. Food amounts of beets are very unlikely to cause trouble. Concentrated beetroot juice or supplements are where I'd be a touch more careful. If you take hydralazine, just check with your pharmacist or doctor before adding daily beet supplements.

From our pharmacist’s overview on the Hydralazine page

“Hydralazine is the drug doctors reach for when blood pressure needs forcing down, so I read this list of 136 supplement interactions with genuine concern rather than routine caution. Start with the four rated major: two are toxic plants with direct effects on the heart and blood vessels, tyramine can push pressure back up and undo the…”

About Beet

What is Beet?

Beet

Beet, especially beetroot juice, is a nitrate-rich food that may modestly lower blood pressure and slightly improve exercise performance in some people. It is generally safe as a food, but supplement effects are modest and not a substitute for prescribed treatment, so talk with your pharmacist or doctor before relying on it.
