Interaction report

Wine and Glipizide, Metformin

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

Why Are There 2 Interactions?

Wine interacts with whole categories of medication. Glipizide, Metformin falls into 2 of those categories, so it can interact with Wine 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 Wine 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 wine 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

Mixing wine with your Metaglip (that's glipizide plus metformin) can pull your blood sugar in two different directions, which makes it a bit unpredictable. Alcohol blocks your liver from releasing stored sugar, and since glipizide already pushes your body to make more insulin, the combination can drop your blood sugar too low. Watch for shakiness, sweating, confusion, dizziness, or a racing heart, and be aware that these can feel a lot like simply being tipsy.

On the flip side, the sugars in wine can also nudge your readings higher. The bottom line: an occasional small glass with food is usually manageable, but heavy or empty-stomach drinking is risky. Please check with your pharmacist or doctor about what's safe for you.

Concomitant use may increase the risk of lactic acidosis.
Concomitant consumption of large amounts of alcohol can increase the risk of lactic acidosis with metformin.
Severity Moderate Likelihood Possible Evidence C

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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combo pill pairs metformin with glipizide, and wine can complicate both halves. The bigger concern here is with the metformin side. Drinking a lot of alcohol can raise the risk of a rare but serious problem called lactic acidosis, where lactic acid builds up in your blood. Warning signs include unusual tiredness, muscle aches, trouble breathing, stomach pain, and feeling very weak. This is uncommon, but it can be dangerous when it happens.

There's also a second wrinkle: glipizide lowers blood sugar, and alcohol can push your sugar down further, sometimes causing shakiness, sweating, or confusion (low blood sugar). An occasional glass with food is different from heavy drinking. Please check with your pharmacist or doctor about what's safe for you before changing anything.

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 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.
