Banaba and Irbesartan

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Irbesartan

Irbesartan falls under ANTIHYPERTENSIVE DRUGS — the group Banaba interacts with.

Theoretically, concomitant use of banaba and antihypertensive drugs might cause additive effects.
Human and animal research suggests that banaba can lower blood pressure.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Here's the simple version: irbesartan (Avapro) already works to bring your blood pressure down, and banaba may nudge it down a little too. When you stack the two, those effects can add up. This isn't because banaba changes how your body handles irbesartan, it's just two things pulling in the same direction at once.

What that can feel like is blood pressure dropping a bit too far, so think dizziness, lightheadedness when you stand up, tiredness, or feeling a little faint. Keep in mind this is mostly theory plus some lower-quality studies, so it's not a sure thing. Banaba can also lower blood sugar, which matters if you take diabetes medicine. Please check with your pharmacist or doctor before adding it, and don't change your irbesartan on your own.

About Banaba

What is Banaba?

Banaba
  • Blood sugar support
  • Type 2 diabetes
  • Weight management
  • High blood pressure
  • Cholesterol support

Banaba is a leaf extract most often used to help support healthy blood sugar, and small early studies suggest its active compound corosolic acid may modestly lower glucose. The overall evidence is limited and short-term, so it should not replace prescribed diabetes care. Talk to your pharmacist or doctor before trying it, especially if you take blood sugar medicine.

About Irbesartan

What Is Irbesartan Used For?

Brand names: Avapro, Aprovel

Irbesartan tablets — sold as the brand Avapro and as generic irbesartan — are used to treat high blood pressure (hypertension). Bringing blood pressure down lowers the risk of serious events like stroke and heart attack. It can be used alone or alongside other blood pressure medicines.

Irbesartan tablets (including Avapro) are also used to treat diabetic nephropathy — kidney disease caused by diabetes — in people who have type 2 diabetes, high blood pressure, and signs of kidney damage. In this group, it helps slow how quickly the kidney disease gets worse.
