Wine and Metformin, Linagliptin

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. Metformin, Linagliptin 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 Metformin, Linagliptin

Metformin, Linagliptin 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

Jentadueto pairs two diabetes medicines (metformin and linagliptin) that help lower your blood sugar. Mixing alcohol like wine into the picture can pull your blood sugar in two directions, which makes things a little unpredictable. Alcohol blocks your liver from making new sugar, so a glass or two, especially on an empty stomach, can drop your blood sugar lower than you expect. That can leave you feeling shaky, sweaty, lightheaded, or confused.

On the flip side, the sugars in wine can also nudge your levels up, so control gets harder to predict. With metformin specifically, heavy drinking also raises a rare risk of a serious condition called lactic acidosis. An occasional glass with food is usually less of a concern, but please check with your doctor or pharmacist about what is safe for you.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Jentadueto combines two diabetes medicines, and the part that matters here is the metformin. Metformin is not a prodrug, so we are not worried about wine changing how it gets activated. The real concern is a rare but serious problem called lactic acidosis, where acid builds up in the blood. Drinking a lot of alcohol can nudge your body in that direction, and metformin can too, so combining heavy drinking with this medicine stacks those risks.

An occasional glass of wine with a meal is generally low risk for most people. Heavy or binge drinking is the real danger. Watch for warning signs like deep tiredness, muscle aches, trouble breathing, stomach pain, or feeling very cold. Please check with your pharmacist or doctor about what is safe 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.
