Interactions With Medicines

Drinking alcohol while taking certain medicines can cause problems, especially if you're taking pain medicine, anti-anxiety medicine, or antidepressants.

Problems can range from increased drowsiness (if you are taking cold or allergy medicine) to serious liver damage (if taking high doses of acetaminophen, such as Tylenol or other products containing acetaminophen).

Talk to your doctor if you have any questions about drinking alcohol while taking your medicines.

Alcohol-Related Health Problems

Alcohol affects nearly every organ in the body. Alcohol intoxication causes loss of coordination and can lead to car accidents, other injuries (falls, broken bones, and head injuries), and risky behavior (such as unsafe sex).

Alcohol intoxication can be severe enough to cause poisoning and death from too much alcohol. Short-term health effects from alcohol abuse can include sexual problems, difficulty sleeping, anxiety, periods of depression, and high blood pressure.

It can also lead to unsafe decisions about sex, increasing the risk for sexually transmitted diseases and unplanned pregnancy.

Heavy drinking over many years increases the risk for serious health problems including alcohol-related liver disease (hepatitis or cirrhosis,) heart disease, stomach problems, brain damage, cancer, and pancreatitis (inflammation of the pancreas). These diseases can be very painful and many can lead to long-term disability and even death.

Pregnancy and Drinking

Women who are pregnant or might soon become pregnant should not drink alcohol. Alcohol causes birth defects and more subtle long-term problems in babies. It's not known how much alcohol it takes or at what time during a pregnancy the damage happens. For this reason, it's important not to drink alcohol at any time during pregnancy.

Drinking and Driving

Many people are surprised to find out it doesn't take much alcohol to affect their ability to drive a car or boat, or operate machinery safely. Although most states in this country set the blood alcohol limit at 0.08 for driving, a blood alcohol level as low as 0.02 percent can affect your driving skills — especially if combined with taking medicine.


People who drink too much typically have more problems at work, school, with friends and family, and at home. These problems can include arguments with family, friends or co-workers, and missing or being late for family and work commitments. Additionally, people may not perform job duties well. People who drink too much are also at a greater risk for committing, or being a victim of, violence and abuse.
