Taurine and Amiloride

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Amiloride

Amiloride falls under ANTIHYPERTENSIVE DRUGS — the group Taurine interacts with.

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.
Severity Moderate Likelihood Probable Evidence D

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: amiloride is a 'water pill' that helps lower your blood pressure, and taurine may gently nudge your blood pressure down too. Stack the two and those effects can add up, so your pressure could drop a little more than expected. That might leave you feeling lightheaded, dizzy, or wobbly when you stand up quickly.

This is mostly a theoretical concern based on how each one behaves, not a strong proven reaction, so please don't panic. Taurine isn't broken down by amiloride or vice versa, so it's not a metabolism problem. Small amounts in food or one energy drink are unlikely to matter much. If you take taurine regularly, just mention it to your pharmacist or doctor and keep an eye on how you feel.

From our pharmacist’s overview on the Amiloride page

About Taurine

What is Taurine?

  • Exercise performance and endurance
  • Heart health
  • Energy support
  • Eye and nerve health
  • Blood sugar support

Taurine is an amino acid your body makes naturally and that you also get from animal foods. It is widely used in energy drinks and sports supplements, and short-term use appears generally safe for most adults, though the evidence for many claimed benefits is mixed or limited. Talk with your pharmacist or doctor before taking it regularly, especially if you have a health condition or take medications.

About Amiloride

What Is Amiloride Used For?

Brand names: Midamor, Amilamont

Amiloride is used as an add-on treatment with thiazide or other potassium-losing diuretics in people with congestive heart failure or high blood pressure (hypertension).

Its job is to help bring potassium back to normal if the other diuretic has made it too low (hypokalemia). It is also used to prevent low potassium in people at special risk, such as those taking digitalis heart medicine or those with significant heart rhythm problems.
