Olive Oil and Torsemide

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Torsemide

Torsemide falls under ANTIHYPERTENSIVE DRUGS — the group Olive Oil interacts with.

Theoretically, taking olive oil with antihypertensive drugs might have additive effects on blood pressure.
Some clinical and observational research suggests that adding olive oil into the diet, especially in place of saturated fat, is associated with reduced 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: torsemide is a water pill that lowers blood pressure by helping your kidneys flush out extra salt and fluid. Olive oil, especially when it replaces less healthy fats in your meals, may nudge your blood pressure down a little on its own. So the two can stack up, gently pushing your blood pressure in the same direction.

For most people this is a mild, food-level effect and nothing to fear. But if your pressure drops too far, you might feel dizzy, lightheaded, or tired, especially when standing up quickly. The evidence here is modest, and everyday cooking amounts of olive oil are unlikely to cause trouble. If you're starting concentrated supplements or notice these symptoms, please check in with your pharmacist or doctor first.

From our pharmacist’s overview on the Torsemide page

“Torsemide (Demadex, Soaanz) is a water pill for fluid buildup from heart failure, kidney disease, or liver disease, and its supplement list earns genuine caution, with 10 of the 251 flagged ingredients rated major. Most entries either pile onto its blood-pressure-lowering effect or add extra diuretic action that can pull your potassium…”

About Olive Oil

What is Olive Oil?

Olive Oil
  • Heart health
  • Cholesterol support
  • General nutrition (Mediterranean diet)
  • Skin and hair care
  • Mild constipation
  • Anti-inflammatory support

Olive oil, especially extra virgin olive oil, is a healthy fat that forms a cornerstone of the Mediterranean diet and is linked with better heart health. Used as part of a balanced diet it is generally safe for most people, but it is calorie-dense, so portion size matters. Talk with your pharmacist or doctor before using concentrated supplements.

About Torsemide

What Is Torsemide Used For?

Brand names: Demadex, Soaanz

Torsemide tablets are used to treat edema — excess fluid buildup causing swelling — associated with heart failure, renal disease, or hepatic disease. Removing that extra fluid can relieve swelling and make breathing easier.

Torsemide tablets are also used to treat high blood pressure (hypertension). Lowering blood pressure reduces the risk of serious cardiovascular events, including strokes and heart attacks. It can be used alone or alongside other blood pressure medications.
