Interaction report

Beer and Glipizide, Metformin

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. Glipizide, Metformin 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

ANTIDIABETES DRUGS

1 of 2

Why this applies to Glipizide, Metformin

Glipizide, Metformin falls under ANTIDIABETES DRUGS — the group Beer interacts with.

Concomitant use may interfere with blood glucose control.
Alcohol can impair gluconeogenesis and may increase the risk of acute hypoglycemia when used concomitantly with antidiabetes drugs. However, the carbohydrates in beer may also worsen glycemic control in patients with diabetes.
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

Here's the tricky part with mixing beer and your Metaglip (that's glipizide plus metformin). Alcohol blocks your liver from making new sugar, which is one of your body's main backups against a low blood sugar. Since glipizide already pushes your body to release more insulin, drinking beer can stack the odds toward hypoglycemia, meaning shakiness, sweating, confusion, a racing heart, or even passing out, especially if you drink on an empty stomach.

At the same time, the carbs in beer can swing you the other way and raise your numbers, so your control gets unpredictable. There's also a small risk that alcohol plus metformin can stress the body in rarer ways. An occasional drink with food is usually manageable, but please check with your pharmacist or doctor about what's safe for you.

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your combo pill (Metaglip) has two pieces, and the beer concern is mainly about the metformin part. Metformin slightly raises lactic acid in the body, and heavy drinking does the same thing. Stack the two together and you can build up too much acid, a rare but serious problem called lactic acidosis. Watch for unusual tiredness, muscle aches, trouble breathing, stomach pain, or feeling very weak and cold.

There's also the glipizide side: alcohol can make your blood sugar swing, sometimes dropping too low (shakiness, sweating, confusion). An occasional single drink with food is usually fine for most people, but binge drinking is the real risk. Please check with your doctor or me about what's safe for you.

From our pharmacist’s overview on the Glipizide, Metformin page

“Glipizide and metformin (Metaglip) already work hard to pull blood sugar down, which is exactly why this list of 307 ingredients deserves genuine vigilance rather than a shrug. Most of them, 239, can lower glucose on their own, and stacked on this pill the combined effect can tip into true hypoglycemia.”

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.
