Interaction report

Wine and Troglitazone

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. Troglitazone 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 (Major).

Major

HEPATOTOXIC DRUGS

1 of 2

Why this applies to Troglitazone

Troglitazone falls under HEPATOTOXIC DRUGS — the group Wine interacts with.

Concomitant use of alcohol with hepatotoxic drugs may increase the risk of hepatotoxicity.
Concomitant use of excessive amounts of alcohol with potentially hepatotoxic drugs can increase the risk of liver damage.
Severity Major 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..

Here's the thing about troglitazone: it was actually pulled from the market years ago because it could seriously harm the liver. That's exactly why pairing it with wine raises a red flag. Both your medication and the alcohol in wine put stress on the same organ, and stacking them together can add up to real liver trouble.

Watch for warning signs like yellowing of the skin or eyes, dark urine, nausea, belly pain on the upper right side, or unusual tiredness. Regular wine, especially heavier drinking, is the bigger concern here, not a one-time sip. If you've been prescribed this drug or anything like it, please talk with your doctor or pharmacist before drinking any alcohol so they can keep an eye on your liver.

ANTIDIABETES DRUGS

2 of 2

Troglitazone also falls under ANTIDIABETES DRUGS.

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

Troglitazone was a diabetes medicine that helped lower blood sugar (it's actually no longer on the market, but the interaction principle still applies to blood sugar drugs). When you add wine to a blood sugar lowering drug, two things can pull in opposite directions. The alcohol itself can block your liver from releasing stored sugar, which may drop your blood sugar too low. That can leave you shaky, sweaty, dizzy, confused, or with a pounding heart.

On the flip side, the sugars in wine can sometimes nudge your blood sugar up, making control harder to predict. Neither effect is something to panic over, but it's worth a quick chat with your pharmacist or doctor before drinking, and never drink on an empty stomach if blood sugar control is a concern.

  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Troglitazone page

“Most people taking troglitazone (Rezulin) are managing type 2 diabetes, and this list reflects that. The great majority of the 280 flagged ingredients act on blood sugar, most lowering it and a few raising it, so pairing them with a diabetes medication makes glucose control less predictable and can tip it too low.”

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.
