Some of this variation may be genetically determined but the specific underlying mechanism is unknown.31, 32 An individual’s P450 enzyme activity could influence his or her susceptibility to alcohol-medications interactions involving this enzyme. An important pharmacokinetic interaction between alcohol and acetaminophen can increase the risk of acetaminophen-related toxic effects on the liver. Acetaminophen breakdown by CYP2E1 (and possibly CYP3A) results in the formation of a toxic product that can cause potentially life-threatening liver damage. In turn, enhanced CYP2E1 activity increases the formation of the toxic acetaminophen product. To prevent liver damage, patients generally should not exceed the maximum doses recommended by the manufacturers (i.e., 4 grams, or up to eight extra-strength tablets of acetaminophen per day). In people who drink heavily or who are fasting (which also increases CYP2E1 activity), however, liver injury may occur at doses as low as 2 to 4 grams per day.
Why do people take drugs?
Aside from these effects, however, moderate alcohol consumption probably does not interfere with antibiotic effectiveness. Possibly, concerns regarding the concurrent use of alcohol and antibiotics grew from research findings indicating that heavy alcohol use can impair the function of certain immune cells and that alcoholics are predisposed to certain infections. Many people may be both drinking alcohol and taking prescription drugs that interact with alcohol, according to an NIH-funded study.
Differences in alcohol distribution patterns also affect the BALs achieved with a given alcohol dose (Thomasson 1995). Thus, women, whose lower body water creates a smaller fluid volume in which the alcohol is distributed, tend to achieve higher BALs than do men after consuming the same amount of alcohol. The normal loss of lean body weight and increase in body fat that occurs with aging has a similar effect on BALs. The potentially higher BALs can exaggerate alcohol-medication interactions in both women and older people. Aside from this effect of gender and age on BALs, researchers have not reported any other major gender- or age-related differences in susceptibility to alcohol-medication interactions.
- We were surprised by the lack of data to determine simultaneous prevalence given the serious consequences of combined alcohol-AI medication use.
- In children aged 9 or 10 years without any experience of substance use, these genes correlated with parental substance use and externalizing behavior.

Getting to NIMH
The resulting health effects can range from mild (nausea, headaches, loss of coordination) to severe (internal bleeding, heart problems, difficulty breathing). Of note, many persons of Asian descent experience facial flushing, nausea and vomiting when they ingest alcohol as they have an inborn variation in the enzymes used to break down acetaldehyde. The medication disulfiram (Antabuse) uses this mechanism (inhibition of ALDH) to cause those who drink alcohol to experience the flushing reaction. Other medications can induce a disulfiram-like reaction including several antibiotics, nitrates and some of the sulfonylureas. This article reviews the literature on alcohol and medication interactions with a focus on older adults. Beyond the examples noted above, alcohol has the potential to interact negatively with many other commonly prescribed medications.
Increased drug metabolism
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. Your pharmacist or other health care provider can help you determine which medications interact harmfully with alcohol. This pamphlet lists medications that can cause harm when taken with alcohol and describes the effects that can result. The list gives the brand name by which each medicine is commonly known (for example, Benadryl®) and its generic name or active ingredient many at risk for alcohol-medication interactions national institutes of health nih (in Benadryl®, this is diphenhydramine). The list presented here does not include all the medicines that may interact harmfully with alcohol.
Consequently, these patients should be advised to drink alcohol only with or shortly after meals. Many commonly prescribed medications can interact with alcohol, including drugs to treat depression, diabetes, and high blood pressure. In 2021, more than 46 million people in the United States aged 12 or older had at least one substance use disorder, and only 6.3% had received treatment. Moreover, people who use drugs are facing an increasingly dangerous drug supply, now often tainted with fentanyl.
1981—On November 18, intramural NIMH researcher Louis Sokoloff, M.D., Ph.D., received the Lasker Basic Medical Research Award, considered the “American Nobel Prize” of clinical medical research. Previous researchers had found evidence for changing glucose levels in the brain but could not link those changes to specific brain regions. Dr. Sokoloff developed a noninvasive technique to track the movement of a radioactive analog of glucose in the brain, which allowed researchers to measure glucose metabolism and map brain function. This technique paved the way for the development of positron emission tomography (PET) imaging of the living brain. Surgeon General’s Report, Toward a National Plan for the Chronically Mentally Ill, a sweeping effort to improve services and fine-tune various federal entitlement programs for those with severe, persistent mental disorders. 1980—In October, NIMH released preliminary results from its Epidemiological Catchment Area Survey.
- As part of the Helping to End Addiction Long-term® Initiative (NIH HEAL Initiative®), NIMH leads a research program that seeks to optimize the delivery of services for people with opioid use disorders, mental disorders, and suicide risk.
- Alcohol metabolism in the liver generates excessive NADH levels and thus reduces the levels of the compounds needed for gluconeogenesis, thereby contributing to a further drop in blood sugar levels.
- Several indicators significantly increased after exposure to the intervention materials.
- Aside from this effect of gender and age on BALs, researchers have not reported any other major gender- or age-related differences in susceptibility to alcohol-medication interactions.
FIND TREATMENT:
Therefore, patients using opioid-acetaminophen combination products should be cautioned about restricting the total amount of acetaminophen they ingest daily (i.e., they should not take regular acetaminophen in addition to the combination product). The authors conclude that a nonfatal opioid overdose treated in the emergency department is a critical time to identify people with OUD, and an opportunity to offer patients access to treatment inventions, providing linkage to care following their discharge, and making improvements in treatment retention. The Division also provides biostatistical analysis and clinical trials operations expertise for research studies; analyzes and evaluates national mental health needs and community research partnership opportunities; and supports research on health disparities. Shelli Avenevoli, Ph.D., is the Acting Director of the National Institute of Mental Health (NIMH), the lead federal agency for research on mental disorders.
Health status and behaviors
1949—On April 1, NIMH was formally established under the direction of psychiatrist and public health advocate Robert H. Felix, M.D., as one of the first four institutes of the National Institutes of Health (NIH). But with continued use, a person’s ability to exert self-control can become seriously impaired. The Division of Intramural Research Programs (IRP) is the internal research division of the NIMH. Over 40 research groups conduct basic neuroscience research and clinical investigations of mental illnesses, brain function, and behavior at the NIH campus in Bethesda, Maryland. Find out how NIMH engages a range of stakeholder organizations as part of its efforts to ensure the greatest public health impact of the research we support.
2015—On February 6, NIMH announced the creation of the Early Psychosis Intervention Network (EPINET), designed to link treatment centers for early psychosis in a network of evidence-based coordinated specialty care programs. By 2020, EPINET included a data coordinating center, eight scientific hubs, and more than 100 community clinics in a national learning health system aimed at improving services and outcomes for thousands of people experiencing an initial episode of psychosis. 2014—NIMH launched the Emergency Department Screening for Teens at Risk for Suicide study in a network of hospital emergency departments across the United States as a part of the institute’s research agenda for suicide prevention. The study aimed to develop and test a personalized, computer-based suicide risk screening tool for teenagers that could improve screening and enable earlier intervention. In 2021, researchers involved in the study developed a computerized adaptive screening tool, which correctly identified more than 80% of youth who went on to attempt suicide in the three months following screening.
Finally, we cannot exclude selection bias as we excluded participants who reported attending other pharmacies. Risk of experiencing alcohol and medication interactions (AMI) is significant among older adults due to the substantial prevalence of alcohol and medication use in this segment of the population. Given the lack of community-level AMI prevention interventions for older adults, this study aimed to examine the immediate effects of a brief, pharmacy-based intervention to prevent AMI among older adults, as well as assess differential effects by past-month drinking status. A convenience sample of 134 adults aged 59 and older was recruited from four pharmacies in rural Virginia.
Of particular importance are pharmacy-based interventions that target residents of rural communities, as AMI-related hospitalizations are increasing more rapidly among older adults living in rural areas 12. Another result of enzyme induction by chronic heavy drinkers is the increased production of toxic metabolites to the liver during the metabolism of drugs like isoniazid, phenylbutazone and acetaminophen. As many older adults take medications other than these that may have hepatotoxic effects (e.g., statins), those who drink 3 or more drinks per day may have increased risk for liver toxicity. These medications are sedative or sleep-inducing (i.e., hypnotic) agents that are frequently used for anesthesia.
According to recent estimates, 71% of American adults consume alcoholic beverages (Substance Abuse and Mental Health Services Administration 2013). Yet, little is known about the prevalence of alcohol-interactive (AI) prescription medication use among US drinkers. Even after inclusion of potential confounders, results still varied based on participant status as a past-month drinker. Prior to exposure to the intervention, older adults who consumed alcohol were more likely than non-drinkers to discuss their risk for AMI with their doctor or pharmacist.
