Alcohol and Medicines
Many medicines—prescription, over-the-counter, or herbal remedies—can be dangerous or even deadly when mixed with alcohol. Many older people take medications every day, making this a special worry.
Before taking any medicine, ask your doctor or pharmacist if you can safely drink alcohol. Here are some examples of problems caused by mixing alcohol with some medicines:
- If you take aspirin and drink, your risk of stomach or intestinal bleeding is increased.
- When combined with alcohol, cold and allergy medicines (the label will say "antihistamines") may make you feel very sleepy.
- Alcohol used with large doses of acetaminophen, a common painkiller, may cause liver damage.
- Some medicines, such as cough syrups and laxatives, have high alcohol content. If you drink at the same time, your alcohol level will go up.
- Alcohol used with some sleeping pills, pain pills, or anxiety/anti-depression medicine can be deadly.
Mixing alcohol and medicines can be harmful. Alcohol, like some medicines, can make you sleepy, drowsy, or lightheaded. Drinking alcohol while taking medicines can intensify these effects. You may have trouble concentrating or performing mechanical skills. Small amounts of alcohol can make it dangerous to drive, and when you mix alcohol with certain medicines you put yourself at even greater risk. Combining alcohol with some medicines can lead to falls and serious injuries, especially among older people.
Medicines may have many ingredients
Some medications—including many popular painkillers and cough, cold, and allergy remedies—contain more than one ingredient that can react with alcohol. Read the label on the medication bottle to find out exactly what ingredients a medicine contains. Ask your pharmacist if you have any questions about how alcohol might interact with a drug you are taking.
Some medicines contain alcohol
Certain medicines contain up to 10 percent alcohol. Cough syrup and laxatives may have some of the highest alcohol concentrations.
Alcohol affects women differently
Women, in general, have a higher risk for problems than men. When a woman drinks, the alcohol in her bloodstream typically reaches a higher level than a man’s even if both are drinking the same amount. This is because women’s bodies generally have less water than men’s bodies. Because alcohol mixes with body water, a given amount of alcohol is more concentrated in a woman’s body than in a man’s. As a result, women are more susceptible to alcohol-related damage to organs such as the liver.
Older people face greater risk
Older people are at particularly high risk for harmful alcohol–medication interactions. Aging slows the body’s ability to break down alcohol, so alcohol remains in a person’s system longer. Older people also are more likely to take a medication that interacts with alcohol—in fact, they often need to take more than one of these medications.
Timing is important
Alcohol and medicines can interact harmfully even if they are not taken at the same time.
Remember...
Mixing alcohol and medicines puts you at risk for dangerous reactions. Protect yourself by avoiding alcohol if you are taking a medication and don’t know its effect. To learn more about a medicine and whether it will interact with alcohol, talk to your pharmacist or other health care provider.
