Wine and Quinidine

Here is the interaction we found between these two, with the evidence behind it.

Major

HEPATOTOXIC DRUGS

Why this applies to Quinidine

Quinidine 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..

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

Here's the simple version: quinidine is one of those medicines your liver has to process, and it can occasionally stress the liver on its own. When you regularly drink wine on top of it, you're asking your liver to handle two things that can each be hard on it. The concern isn't that the wine changes how well quinidine controls your heartbeat. It's that the combination may raise your odds of liver irritation or damage over time, especially with heavier or frequent drinking.

Warning signs to watch for would be yellowing of the skin or eyes, dark urine, belly pain on the upper right side, or unusual tiredness. An occasional small glass is far less worrying than regular or heavy drinking. Before you mix the two, please check with your doctor or pharmacist so they can weigh in for your situation.

From our pharmacist’s overview on the Quinidine page

“Grapefruit belongs nowhere near quinidine. The juice blocks the main enzyme that clears this heart rhythm medicine, so quinidine levels can climb into dangerous territory, and it leads a list of 207 supplement and herbal ingredients I would treat with real seriousness, 15 of them rated major.”

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.

About Quinidine

What Is Quinidine Used For?

Brand names: Quinaglute Duratabs, Quinaglute, Duraquin, Cardioquin, Cin-Quin, Quinora, Lin-Qin, Quinova, Quinidex Extentabs

Quinidine is used to treat certain abnormal heart rhythms. It can help restore normal rhythm in symptomatic atrial fibrillation/flutter, and it can lengthen the time between episodes in some high-risk patients. It is also used for recurrent, life-threatening ventricular arrhythmias such as sustained ventricular tachycardia.

Quinidine Sulfate tablets are also approved to treat life-threatening Plasmodium falciparum malaria. The Quinidine Gluconate extended-release tablet label does not list this use.
