Beet and Terazosin

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

Minor

Antihypertensive Drugs

Why this applies to Terazosin

Terazosin 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 gist with terazosin (Hytrin) and beets. Terazosin is an alpha-blocker that relaxes your blood vessels to lower blood pressure and ease urinary symptoms from an enlarged prostate. Beets are rich in nitrate, which your body can turn into nitric oxide, and that also relaxes blood vessels. So in theory, stacking the two could nudge your blood pressure a little lower than usual.

The good news is that this is rated minor, and the research shows any effect from beets tends to be small and short-lived rather than dramatic. Still, terazosin already carries a risk of dizziness or lightheadedness, especially when you stand up quickly (the so-called "first-dose" drop). If you enjoy beetroot juice regularly and notice you feel woozy, just mention it to your pharmacist or doctor. No need to stop eating beets, but it's worth a quick chat.
