These are often used to treat infections alongside other drugs for bacterial infections, such as urinary tract infections. The use of alcohol with sulfonamides has been found to cause facial flushing, but otherwise, data on risk are limited. Ethionamide package labeling recommends against excessive alcohol consumption (113). Ethionamide, often used in combination with pyrazinamide, is known to cause hepatotoxicity (113). An observational study of 55 alcoholics with TB found that mild liver impairment in alcoholics is not a contraindication for treatment with ethionamide (114). Of the 55 patients in that study, 30 received ethionamide and three patients developed parenchymal liver damage.

Penicillins.

Some people assume that alcohol will stop antibiotics from working properly, while others believe that it will cause side-effects. When staff in a London genitourinary clinic surveyed more than 300 patients they found that 81% believed the former assumption, with 71% believing the latter. Since alcohol lowers the seizure threshold, doctors advise people with a history of seizures to avoid mixing alcohol and fluoroquinolones. Mixing alcohol with fluoroquinolone antibiotics such as ciprofloxacin may increase these mental health side effects.

1. Acute alcohol use, binge drinking, and chronic alcohol use can all be harmful, whether you take medication or not.
2. To improve your heart health, small bursts of action can make a big difference.
3. Scientists are still working to understand all the different ways alcohol affects your immune system.
4. It’s important to know if there are concerns about how effective the antibiotic might be for your infection based on any drug interactions, including alcohol.

Mixing antibiotics and alcohol can make these side effects worse. Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Alcohol appears to lead to slowed «gastric emptying» when combined with erythromycin ethylsuccinate.

Metronidazole.

There are several antibiotics that people should not mix alcohol with. Not only can they interfere with the way the antibiotics work, but they can also cause a number of harmful side effects. Scientists have linked heavy and binge drinking with an impaired immune system. People with an impaired immune system have a higher risk of infection. Metronidazole is a nitroimidazole antibiotic that doctors prescribe to treat abdominal infections, sexually transmitted infections, and other anaerobic bacteria-related infections.

Tyramine is a substance present in tap beers and red wine, among other products. Depending on the type of antibiotic someone is taking, doctors may recommend limiting or avoiding alcohol intake. Like many types of antibiotics, alcohol is broken down and processed by your liver before it can exit your body. When your liver is already working to help fight infection, adding alcohol to the mix can overwork it. In rare cases, this can cause drug-induced liver toxicity (swelling of your liver).

Read on to learn about the potential consequences of mixing alcohol with prescription medications, with a specific emphasis on the potential dangers of mixing alcohol with amoxicillin. The directions on antibiotics often advise you to take every dose with water and warn against consuming dairy products and fruit juices. These products can interact with antibiotics and affect how your body absorbs them. Be careful with grapefruit and citrus juices, and wait at least three hours after taking your prescription before consuming dairy products. As well as its antibacterial effect, linezolid reduces the action of enzymes called monoamine oxidase-A and monoamine oxidase-B.

If you have any of these side effects, avoiding or limiting alcohol during your amoxicillin celebrities with fas treatment may help relieve them. Alcohol and amoxicillin can cause similar side effects, and combining the two can worsen or increase your risk of having these side effects. Amoxicillin and certain other prescription medications can also cause these side effects. While alcohol does not interact with every prescription drug, in many cases, it can worsen existing side effects or cause additional, independent side effects. It’s also used along with other medications to treat stomach ulcers caused by the bacterium called Helicobacter pylori (H. pylori).

Table 1: Common Antibiotic and Alcohol Interactions

Despite the widespread belief that metronidazole is contraindicated with alcohol consumption, the literature raises doubt. Interaction occurs with unclear frequency, and, when it occurs, it ensues with varying severity. The effects of alcohol on levofloxacin, moxifloxacin, and trovafloxacin were studied in a rat pneumonia model (24). The mean serum Cmax and AUC were higher in the ethanol-fed group for all FQs, with a statistically significant difference in the moxifloxacin group. The ethanol-fed group was found to have decreased protein binding and an increased free fraction of antibiotics.

Examples of Antibiotic + Alcohol Drug Interactions

Healthcare providers write over 200 million antibiotic prescriptions every year, according to the U.S. While these medications aren’t appropriate for every illness, they’re effective for treating certain infections. If you need to avoid alcohol, be sure you check all of your food and medicine labels to be sure they don’t contain alcohol.
