Can You Drink Alcohol With Polycythemia Vera?

Note: While research on alcohol is evolving, the World Health Organization says drinking less or not at all is better for your health.

There is no universal recommendation. Whether drinking is wise depends on the severity of your symptoms, your medications, your alcohol tolerance, and any underlying health conditions. “Alcohol is not automatically off-limits for most people with PV,” says Aaron Gerds, MD, a hematologist and oncologist at Cleveland Clinic in Ohio. “But it should be consumed thoughtfully and in moderation, with attention to hydration and symptom control.”

How Alcohol Affects PV

“Some patients find that alcohol can trigger or worsen headaches, flushing, dizziness, or itching,” says Dr. Gerds. “The impact varies considerably from person to person. Some individuals notice no difference, while others find that even small amounts can aggravate symptoms.”

Alcohol and Blood Clot Risk

Dehydration doesn’t change your number of red blood cells, but it reduces the amount of liquid in your blood, so it becomes more concentrated and thicker.

“While moderate alcohol consumption has not been shown to specifically increase clotting risk in PV, heavy alcohol use can contribute to dehydration and other health issues that may negatively affect overall cardiovascular health,” Gerds says.

Is It Safe to Drink During Flare-Ups?

Provided their doctor approves, Gerds says many people whose PV is well controlled can safely drink alcohol in moderation. “One common misconception is that alcohol directly fuels the disease,” he says. “There is currently no evidence that moderate alcohol consumption accelerates the progression of polycythemia vera.”

But there are times when it may be smarter to abstain. “During flare-ups, when symptoms are active, or if you are having trouble with headaches, itching, dizziness, or dehydration, it is usually best to avoid alcohol or keep it to a minimum,” says Marisa Ponzo, MD, PhD, a dermatologist at the North York Dermatology Clinic in Toronto. “The key is to pay attention to how your body responds.”

Does Alcohol Interact With PV Medications?

• low-dose aspirin
• hydroxyurea (Hydrea)
• peginterferon alfa-2a (Pegasys)
• ropeginterferon alfa-2b-njft (Besremi)
• ruxolitinib (Jakafi)

While there are no specific interactions with these drugs, alcohol can worsen medication side effects and disease symptoms.

“Patients taking hydroxyurea, interferons, or ruxolitinib should discuss alcohol use with their physician because both medications and alcohol can affect the liver,” says Gerds. “Excessive alcohol consumption may increase the risk of liver-related complications.”

Ponzo says that another potential concern is increased stomach irritation or bleeding risk when combined with aspirin. “[Alcohol] can also add to fatigue or dizziness,” she says.

Are Some Alcoholic Drinks Safer for PV Than Others?

There is no strong evidence that one type of alcoholic beverage is safer than another for people with PV, Gerds says. “Patients should pay attention to their own symptom patterns,” he says, and note whether certain beverages trigger symptoms like itching, flushing, or headaches.

“Lower-alcohol options, such as a small glass of wine or a light beer, may be easier on symptoms than high-proof cocktails or binge drinking,” says Ponzo. “In general, the amount of alcohol matters more than the type, and sugary mixers or very strong drinks may be more likely to make you feel worse.”

“If you do drink, choose smaller amounts, drink slowly, and have water alongside alcohol to reduce dehydration,” she says.

Safe Drinking Practices for People With PV

“The safest approach is moderation,” says Ponzo. “The bottom line is that for many people with PV, alcohol is not completely off-limits, but it is best kept to a minimum. If your symptoms are active, you are dehydrated, or you are taking medications that raise bleeding or liver concerns, it is wise to be extra cautious and check with your hematologist.”
