Alcohol can intensify these effects because it also depresses the central nervous system. When used together, the risk of falls, injuries, and car crashes increases. The combination can also slow breathing, especially if an opioid is also taken at the same time.<\/p>\n
To reduce your risk:<\/p>\n
Avoid alcohol on days you take these medications or supplements.
Do not drive or operate machinery if you feel drowsy.
Be extra cautious when starting a new medication or supplement, taking higher doses, or if you are sleep-deprived.<\/p>\n
Even if you have taken sedatives before without problems, adding alcohol can make side effects unpredictable and dangerous.\n<\/p>\n
Herbal Supplements and Sleep Aids With Sedating Effects<\/p>\n
Some herbal supplements and over-the-counter sleep aids can also have sedative effects and may increase drowsiness or impair coordination when combined with alcohol. Examples include:<\/p>\n
Melatonin, which can increase sleepiness and impair reaction time
Valerian root, which may enhance alcohol\u2019s sedating effects
Lavender supplements, sometimes used for anxiety or sleep
Kava, which has central nervous system depressant effects and has also been linked to liver damage
\n 5. Warfarin and Other Anticoagulants <\/p>\n
Alcohol can increase bleeding risk in people who take warfarin by affecting how the medication works in the liver. Studies show that heavy or binge drinking is linked to a higher risk of major bleeding in people on warfarin.<\/p>\n
If you take warfarin, avoid binge drinking and tell your healthcare provider about any alcohol use or sudden changes in your alcohol consumption (including decreases).<\/p>\n
Get medical advice right away if you notice:<\/p>\n
Nosebleeds that won’t stop
Black or tarry stools
Vomiting blood
Large or unexplained bruises<\/p>\n
6. Diabetes Medications That Can Cause Hypoglycemia <\/p>\n
Alcohol can lower blood sugar and make it harder for the body to correct low glucose levels that may occur with some medications. Drinking alcohol in the evening can increase the risk of hypoglycemia (low blood sugar) the next morning. Alcohol also raises the risk of hypoglycemia when combined with insulin or sulfonylureas.<\/p>\n
To reduce your risk:<\/p>\n
Drink any alcohol with food.
Avoid drinking on an empty stomach.
Check your blood sugar levels more often.<\/p>\n
Remember that alcohol intoxication can feel like low blood sugar, so test rather than guess. If symptoms are severe or don\u2019t improve with treatment, seek medical care.<\/p>\n
7. Antibiotics and Other Antimicrobials <\/p>\n
Alcohol can interfere with some antibiotic medications, either by making them less effective or increasing side effects. Alcohol-related risks vary by drug.<\/p>\n
Possible effects include:<\/p>\n
Reduced effectiveness: Some antibiotics, such as erythromycin and doxycycline, may not work as well in people who drink alcohol, especially with long-term or heavy alcohol use. Because risks differ by medication\u2014and data are limited for some drug classes, including antiretrovirals<\/a>\u2014follow your healthcare provider’s advice and ask about alcohol use when starting an antimicrobial.\n<\/p>\n 8. St. John’s Wort <\/p>\n St. John’s wort<\/a> is an herbal supplement sometimes used for mild depressive symptoms. Combining St. John’s wort with alcohol may increase side effects such as dizziness, drowsiness, and impaired concentration.\n<\/p>\n 9. Antidepressant Medications <\/p>\n Alcohol can worsen side effects of many antidepressant medications<\/a>, including drowsiness, dizziness, and impaired coordination. Some antidepressants\u2014such as monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants<\/a>\u2014carry higher risks when combined with alcohol, including potentially dangerous changes in blood pressure and greater central nervous system depression.<\/p>\n Alcohol can also worsen mood symptoms and interfere with treatment response. Because of this, people taking antidepressants may want to limit or avoid alcohol and discuss alcohol use with their healthcare provider.<\/p>\n Talk to a Healthcare Provider for Guidance <\/p>\n Alcohol can increase harm with several common medications and a few higher-risk supplements\u2014particularly those that affect breathing, bleeding, blood sugar, or the liver.\n<\/p>\n When in doubt, bring a list of your medications and supplements to the pharmacy. Interaction checks are quick, personalized, and can prevent serious harm. If you’re unsure whether a product is compatible with alcohol use, the safest approach is to skip drinking and get individualized guidance from your healthcare provider.\n<\/p>\n Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.

\nIncreased liver stress: Alcohol can raise the risk of liver injury with certain antifungal<\/a> and tuberculosis medications, such as ketoconazole, griseofulvin, isoniazid, and rifampin.
\nPhysical reactions: A small number of antimicrobials, including cefotetan, ceftriaxone, and metronidazole, may trigger flushing, nausea, vomiting, headache, fast heart rate, or low blood pressure when combined with alcohol.<\/p>\n![\"Photo](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/01\/Pe_Photographic_elements_photo_4004_65-03e93e03913047838bfa0ca549c75c8d.jpg\")
