    Alcohol-Drug Interactions

    The interaction between many medications and alcohol can lead to a significant increase in one's risk of illness, injury, or even death. When certain medications and alcohol compete in the body for absorption, the potency of the medication and/or alcohol is often increased. There is no set formula for what will happen when an individual consumes both alcohol and a medication. Each person is different, and the results of this type of potentially fatal cocktail vary based on the type and quantity of medication and alcohol ingested, the time frame involved, the individual's tolerance to both the medication and to alcohol, as well as a series of unpredictable, unique factors. To be safe, never mix alcohol with any type of medication, whether prescription or over-the-counter, before first checking with a licensed health care professional.

    Use the following chart to get a better understanding of the potentially fatal effects of mixing alcohol and medications. DO NOT use this chart as the sole basis for determining whether or not it is safe to consume alcohol while taking a certain medication. Be sure to check with a health care provider before mixing alcohol and a certain medication, and when in doubt, stay sober!
