Interaction report

Beer and Minoxidil

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Beer interacts with whole categories of medication. Minoxidil falls into 2 of those categories, so it can interact with Beer in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

VASODILATORS

1 of 2

Why this applies to Minoxidil

Minoxidil falls under VASODILATORS — the group Beer interacts with.

Concomitant use may increase the risk of acute hypotension.
Acute alcohol intoxication can increase the risk of hypotension and additive effects with vasodilators.
Severity Moderate Likelihood Probable Evidence C

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 explains PharmD, Clinical Pharmacist

When you take minoxidil for blood pressure, it works by relaxing and widening your blood vessels. Beer does something similar in the moment, because alcohol can also lower blood pressure. Put the two together and the effects can stack up, so your pressure may drop more than you want.

In real life that can feel like dizziness, lightheadedness, a faster heartbeat, or feeling faint, especially when you stand up quickly. The bigger concern is heavier drinking or getting tipsy, not necessarily one small beer. This is a well-recognized combination, so it's worth a quick chat with your doctor or pharmacist about how much alcohol, if any, is okay for you, and they may want to check your blood pressure.

ANTIHYPERTENSIVE DRUGS

2 of 2

Minoxidil also falls under ANTIHYPERTENSIVE DRUGS.

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

If you're taking minoxidil as a pill to lower your blood pressure, mixing in beer can pull your numbers in two directions, and that's the tricky part. Over time, regular drinking tends to raise blood pressure, which can work against what minoxidil is trying to do. But on a night when you drink more heavily, alcohol can widen your blood vessels too, stacking on top of minoxidil and dropping your pressure too low.

That can mean dizziness, lightheadedness, a fast heartbeat, or feeling faint when you stand up. The evidence here is moderate, not rock-solid, but it's reasonable to be cautious. Please don't change your minoxidil on your own. Just chat with your pharmacist or doctor about how much alcohol, if any, fits safely with your treatment.

From our pharmacist’s overview on the Minoxidil page

“American hellebore heads the concerns for anyone taking minoxidil (Loniten, Rogaine), because even small amounts of its alkaloids lower blood pressure on their own, a dangerous match with one of the most potent pressure-lowering drugs prescribed. It is one of four major-rated entries among the 139 supplements and herbs on record, and t…”

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 Minoxidil

What Is Minoxidil Used For?

Brand names: Loniten, Rogaine, Minoxidil

Minoxidil tablets are used to treat high blood pressure (hypertension) — specifically in patients who haven't responded well to other blood pressure medications. They are a powerful option reserved for difficult-to-control cases.

Topical minoxidil products — including solutions, sprays, gels, and foams from many brands — are used to regrow hair on the top of the scalp (called the vertex). Products labeled for men and for women may differ; for example, Bosley MD Regular Strength for Women and Dizop Minoxidil Topical Gel are each labeled for their specific intended users.
