Flaxseed and Talinolol

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Talinolol

Talinolol falls under ANTIHYPERTENSIVE DRUGS — the group Flaxseed interacts with.

Theoretically, flaxseed might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Clinical research shows that daily flaxseed consumption, especially for longer than 12 weeks, modestly reduces blood pressure.
Severity Moderate Likelihood Possible Evidence D

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

Talinolol is a beta-blocker used to help lower blood pressure. The concern here is pretty simple: flaxseed, when eaten regularly as a supplement for several weeks, can nudge your blood pressure down a little on its own. Stack that gentle effect on top of Talinolol, and the two together might lower your pressure a bit more than expected.

If your blood pressure drops too far, you could feel dizzy, lightheaded, tired, or wobbly when you stand up quickly. To be clear, this is a theoretical, mild concern based on how each one works, not a dangerous combination. A sprinkle of flaxseed on your oatmeal is unlikely to matter, but daily supplement-sized doses might. If you go that route, check in with your pharmacist or doctor and keep an eye on your numbers.

From our pharmacist’s overview on the Talinolol page

“Most of what talinolol does, slowing the heart and lowering blood pressure as a beta-blocker, is exactly what the supplements on this page can amplify or undo, so I would approach any combination here with genuine care. The largest share adds to its blood-pressure-lowering effect, risking dizziness, a slow pulse, or fainting, while a f…”

About Flaxseed

What is Flaxseed?

Flaxseed
  • Constipation and digestive health
  • High cholesterol
  • Heart health
  • Menopausal symptoms
  • Blood sugar support

Flaxseed is a nutritious food rich in fiber, omega-3 fats (ALA), and plant compounds called lignans. It is most reliably helpful for constipation and may modestly lower cholesterol, but evidence for many other uses is mixed or limited. It is generally safe as a food, but talk to your pharmacist or doctor before using it as a supplement, especially if you are pregnant or breastfeeding.
