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

Whether to drink alcohol is a personal choice, but for people with sickle cell disease, an inherited blood disorder that causes red blood cells to become C-shaped and stick together, that choice comes with more things to consider. Drinking alcohol may make the condition harder to manage or even set off a pain crisis or other complications.

Guidance on drinking varies for people with sickle cell. In the United States, health organizations generally advise people with sickle cell disease to limit alcohol, while in some countries, such as England, experts recommend not drinking at all.

Here’s what you need to consider when deciding whether to drink alcohol, as well as what amounts experts consider safe.

How Alcohol Affects Sickle Cell Disease

C-shaped (or sickle-shaped) red blood cells can block blood flow and cut off oxygen to tissues and organs, which can cause episodes of severe pain and other serious complications.

Dehydration affects blood flow and can make blood cells stick together more — that’s why patients with sickle cell are always advised to stay hydrated, says Nirmish Shah, MD, an associate professor of medicine and pediatrics at Duke University School of Medicine in Durham, North Carolina. “Alcohol, however, leads to a dehydrated state,” he says.

Your liver and kidneys are also a concern, because sickle cell disease can damage those organs. “Patients need to be careful, since alcohol can cause toxicity to the liver and kidneys,” says Dr. Shah.

People who get blood transfusions to treat sickle cell disease can also build up too much iron in their organs, a problem called iron overload.

People who have iron overload may be at higher risk of a liver injury related to alcohol, says Payal Desai, MD, director of the Adult Sickle Cell Clinic at Atrium Health Levine Cancer in Charlotte, North Carolina.

Alcohol and Your Tolerance

“With sickle cell disease, alcohol can lead to more severe complications at lower doses, due to dehydration,” says Dr. Desai.

Being female also lowers a person’s tolerance for alcohol, because women reach higher blood alcohol levels than men of the same weight after drinking equal amounts.

But there’s no data showing that alcohol affects men and women with sickle cell disease differently, Desai says.
A bone marrow transplant is a potential cure for sickle cell disease (as are two gene therapies).

Whether you can drink safely after a bone marrow transplant depends on how long it’s been since your transplant and what other medications you take, says Desai. There’s no general guidance, so talk with the team providing your care.

Is It Safe to Drink Before, During, or After a Pain Crisis?

People with sickle cell disease can have pain crises, also called vaso-occlusive crises, which are episodes of severe pain caused by blocked blood flow. The pain is most often in the back, legs, and arms, and sometimes the chest.

Alcohol has directly led to pain crises in some patients, says Shah. “During, as well as before or after, a pain crisis, we advise patients to avoid alcohol, since it can dehydrate them and cause further issues. During these times, the focus should be on recovery, pain control, rest, and aggressive hydration,” he says.

Does Alcohol Interact With Sickle Cell Disease Medications?

Alcohol may interact with sickle cell medications, says Shah. Talk with your doctor before drinking if you take any of these medications:

  • Opioids, Such as Oxycodone (OxyContin, Roxicodone) Doctors may prescribe opioids for serious sickle cell pain or pain that lasts for a long time.

    Don’t drink alcohol while you’re taking opioids, because having both in your system at once raises the risk of side effects, says Shah. Combining the two can cause profound sedation, dangerously slowed breathing, coma, and death.

  • Ibuprofen (Advil, Motrin) and Acetaminophen (Tylenol) Over-the-counter pain relievers such as ibuprofen and acetaminophen are sometimes used to treat mild to moderate sickle cell pain.

    While drinking small amounts of alcohol while taking these drugs may be okay (talk with your doctor), in larger amounts it raises the risk of stomach bleeding and liver issues.

  • Blood Thinners, Such as Warfarin (Coumadin, Jantoven) Blood clots are a possible complication of sickle cell disease.

    For people who take blood thinners long term, alcohol may affect these medications, says Desai. Drinking is one of the strongest risk factors for major bleeding while taking warfarin.

  • Hydroxyurea (Droxia, Siklos) and L-Glutamine (Endari) Hydroxyurea makes red blood cells less likely to sickle, and L-glutamine reduces damage to red blood cells.

    Alcohol may interact with these treatments, says Shah. Talk with your doctor about drinking if you’re taking one of these medications.

Are Some Alcoholic Drinks Safer for Sickle Cell Disease Than Others?

“In general, there is no specific type of alcohol that is better than others. It is the alcohol content and the effect on a patient that is important,” says Shah.

To keep track of how much alcohol you’re drinking, it helps to know what counts as one drink. In the United States, a standard drink contains about 14 grams of pure alcohol, the amount in:

  • A 12-ounce can of regular beer (5 percent alcohol)
  • A 5-ounce glass of wine (12 percent alcohol)
  • A 1.5-ounce shot of distilled spirits (40 percent alcohol)
Keep in mind that the drinks you’re served may be bigger than a standard drink.

Safe Drinking Practices for People With Sickle Cell Disease

Questions about alcohol are very common among people with sickle cell disease, Shah says. The general advice isn’t to avoid drinking completely, but rather to be very careful about how much you drink.

“While a rare, small amount of alcohol is okay, more than one drink or drinking on a regular basis may significantly worsen the underlying sickle cell disease,” says Desai.

If you do choose to drink, these steps can help lower your risk:

Talk with your care team. Ask your hematologist whether alcohol is safe for you, especially if you take medications.

Stay hydrated. Drink enough nonalcoholic fluids to avoid dehydration.

Don’t drink to cope with pain. Using alcohol to numb sickle cell pain or to cope with feelings about the disease can lead to addiction.

Talk to your doctor if you need help with pain control or emotional coping.
Still, the safest choice is not to drink at all. Research increasingly shows that no amount of alcohol is risk-free.
