Wine and Metolazone

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Metolazone

Metolazone falls under ANTIHYPERTENSIVE DRUGS — the group Wine 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

Here's the deal with mixing wine and metolazone. This is a water pill that lowers blood pressure and clears extra fluid, and alcohol can pull your blood pressure in two different directions. Drinking regularly over time tends to push blood pressure up, which can work against your medication. But a drink on an empty stomach, or several in one sitting, can drop your pressure too far when added to metolazone.

That combined dip may leave you dizzy, lightheaded, or faint, especially standing up quickly, since metolazone is already making you lose fluid. The evidence here is moderate, not alarming, but worth respecting. If you enjoy a glass now and then, ask your pharmacist or doctor what's reasonable for you.

About Wine

What is Wine?

  • Social and relaxation use
  • Heart health (popular belief)
  • Antioxidant intake
  • Aiding digestion (traditional use)
  • Culinary flavoring

Wine is an alcoholic beverage made from fermented grapes and is not a true dietary supplement or medicine. Despite popular claims about heart benefits, the alcohol it contains carries real health risks, and no amount of drinking can be recommended to improve health. If you drink, do so in moderation, and avoid alcohol entirely during pregnancy or if you have certain medical conditions.
