Beer and Triamterene

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Triamterene

Triamterene falls under ANTIHYPERTENSIVE DRUGS — the group Beer interacts with.

Theoretically, concomitant use may interfere with blood pressure control.
Clinical research suggests that consumption of alcohol can increase both systolic and diastolic blood pressure. However, acute alcohol intoxication can also increase the risk of hypotension and additive effects with antihypertensive drugs.
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

Triamterene is a 'water pill' that helps your body shed extra fluid while holding onto potassium. Beer can pull your blood pressure in two directions, so it doesn't mix neatly with a medication like this. Drinking regularly over time tends to raise blood pressure, which can work against what triamterene and your other heart or liver medicines are trying to do.

On the flip side, having several drinks at once can drop your pressure too low, especially when stacked with a diuretic. That may leave you feeling dizzy, lightheaded, or faint when you stand up. The evidence here is moderate, not alarming, but the safest amount of alcohol is none. Please check with your pharmacist or doctor about what's right for you.

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

From our pharmacist’s overview on the Triamterene page

“Because triamterene (Dyrenium) both lowers blood pressure and hangs onto potassium, its supplement list calls for real vigilance. Six of the 165 ingredients on file carry a major rating, and those six deserve your attention before any others.”

About Beer

What is Beer?

Beer
  • Social and recreational drinking
  • Relaxation
  • Heart health (popular belief)
  • Bone health (popular belief)
  • Source of antioxidants and B vitamins

Beer is an alcoholic beverage that contains some minerals, B vitamins, and plant compounds from hops and grain, but it is not a health supplement. Any possible benefits come only from light-to-moderate intake, and they are easily outweighed by the well-known harms of alcohol. The safest amount of alcohol for health is none, and beer should be avoided in pregnancy and breastfeeding.

About Triamterene

What Is Triamterene Used For?

Brand name: Dyrenium

Triamterene capsules are used to treat edema — excess fluid buildup in the body — linked to several conditions, including congestive heart failure, cirrhosis of the liver, and nephrotic syndrome (a kidney disorder causing protein loss and swelling). It is also used for steroid-induced edema, idiopathic edema (fluid retention with no clear cause), and edema due to secondary hyperaldosteronism (overproduction of a hormone that causes the body to hold onto sodium and water).

It can be used on its own or alongside other diuretics, either to boost fluid removal or to help preserve potassium levels. Both Dyrenium and Triamterene capsules share the same approved uses as described above.
