What Happens When You Drink Alcohol on Antibiotics?

Antibiotics are powerful medications used to treat bacterial infections, ranging from respiratory illnesses to urinary tract infections (UTIs). They work by either killing bacteria or preventing their growth. While antibiotics are vital in combating bacterial infections, their interaction with substances like alcohol is a matter of concern for many.

Drinking alcohol while taking antibiotics can lead to various adverse effects. The specific reaction depends on the type of antibiotic and the amount of alcohol consumed. Common outcomes of this interaction may include:

Increased Side Effects

Many antibiotics can cause side effects like dizziness, drowsiness, and upset stomach. Alcohol can intensify these effects.

Decreased Effectiveness of Antibiotics

While not always the case, some antibiotics can be less effective if you drink alcohol. This is because alcohol can interfere with the body’s ability to absorb some types of antibiotics.

Adverse Reactions

Certain antibiotics, when mixed with alcohol, can cause a severe reaction. Symptoms may include rapid heart rate, changes in blood pressure, headache, and nausea. 

Liver Stress

Both antibiotics and alcohol can be hard on your liver. Consuming them together can increase the strain, potentially leading to liver damage.

Dehydration and Nutrient Depletion

Alcohol is a diuretic, which can lead to dehydration. Combined with antibiotics, this can hinder your recovery from the infection.

Impact on Immune System

Alcohol can weaken your immune system, which can be counterproductive when you’re trying to fight off an infection with antibiotics. Does alcohol make the pill less effective?

It’s always best to avoid alcohol while taking antibiotics or at least to limit consumption. If in doubt, consult with your healthcare provider for specific guidance based on the type of antibiotic you’re taking and your overall health.

Unveiling the Truth: What Medication Can You Not Drink Alcohol With?

Alcoholic drinks can interact with various medications, sometimes leading to dangerous or undesirable effects. Understanding these interactions ensures your safety and the effectiveness of the medication. Here’s a list of common medication types that generally should not be mixed with alcohol:


Most commonly prescribed antibiotics can cause a severe reaction when combined with alcohol, including nausea, vomiting, skin flushing, and rapid heart rate.


Mixing alcohol with antidepressants can worsen depression symptoms, increase drowsiness, and lead to a dangerous increase in blood pressure.

Pain Relievers

Over-the-counter pain medications and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen can cause liver damage, stomach bleeding, and ulcers when mixed with alcohol.

Anxiety and Sleep Medications

Benzodiazepines and other sedatives combined with alcohol can lead to extreme drowsiness, dizziness, slowed or difficulty breathing, impaired motor control, unusual behaviour, and memory problems.

Blood Thinners

The effectiveness of some blood thinning medications can be altered by alcohol, increasing the risk of internal bleeding.

Diabetes Medications

Alcohol can cause a sudden spike or drop in blood sugar levels, which can be dangerous for people taking insulin or other diabetes medications.

Cough Syrups and Laxatives

Many of these over-the-counter products contain alcohol. Consuming them with additional alcohol can increase the alcohol content in your body unexpectedly.

Heart Medications

Alcohol can interact with heart medications, leading to dizziness or fainting due to a sudden drop in blood pressure. Alcohol can also interact with statins, increasing the risk of liver damage.

Opioid Pain Medications

Combining opioids with alcohol can lead to dangerous respiratory depression, leading to a decrease in breathing rate, potential respiratory failure, and death.

Muscle Relaxants

These can cause sedation and drowsiness, which can be enhanced by alcohol consumption, increasing the risk of accidents.

It’s important to read medication labels and consult a healthcare professional before consuming alcohol when taking any medication. This list is not exhaustive, and there may be other medications that interact with alcohol. Always prioritise safety and seek professional advice when in doubt.

Alcohol Alternatives: Can You Drink Non-Alcoholic Beer on Antibiotics?

When taking antibiotics, many people wonder about safe beverage choices, especially if they’re used to having a drink with their meals or socially. Non-alcoholic beer often comes up as a potential alternative, but is it a safe choice? Here’s what to consider:

Alcohol Content in Non-Alcoholic Beer

Although labelled as “non-alcoholic,” these beers typically still contain a small amount of alcohol, usually less than 0.5% by volume. This is an important factor, as even a minimal alcohol content might be risky with certain antibiotics.

Interaction with Antibiotics

The primary concern with alcohol and antibiotics is the potential for adverse interactions, which can range from increased side effects to reduced effectiveness of the medication. While the alcohol content in non-alcoholic beer is low, it’s not zero. For antibiotics that have a strict no-alcohol warning, it might be best to avoid even these low levels.

Type of Antibiotic

Some commonly prescribed antibiotics have a strong interaction with alcohol, causing severe reactions. If you’re on these medications, it’s best to avoid any form of alcohol, including non-alcoholic beer.

Health Benefits

On the positive side, non-alcoholic beer can offer some health benefits. It’s often rich in antioxidants and can be a good source of vitamins and minerals. Plus, it helps maintain the social aspect of drinking without the alcohol content.

Alternatives to Non-Alcoholic Beer

If you want to avoid risk, there are alternatives like mocktails and alcohol-free wines, or simply choosing non-alcoholic beverages like soda or sparkling water.

Consult Your Doctor

Ultimately, the safest approach is to consult your healthcare provider. They can offer guidance based on the specific antibiotic you’re taking and your overall health.

While non-alcoholic beer might be a safer alternative than regular alcoholic beverages when you’re on antibiotics, it’s not entirely risk-free. It’s essential to consider the type of antibiotic you’re taking and to consult with a healthcare professional if you have any doubts.

Guidelines for Safety: What Not to Do When on Antibiotics

Antibiotics are powerful medications used to treat bacterial infections, and it’s essential to use them correctly to ensure their effectiveness and safety. Here are key guidelines on what not to do when you’re taking antibiotics:

Do Not Mix with Alcohol

Do not consume alcohol while on antibiotics. When you drink alcohol while taking antibiotics, the alcohol can interfere with the effectiveness of the medication and can also increase the risk of side effects like dizziness, drowsiness, and gastrointestinal issues.

Avoid Skipping Doses

It’s essential to take your antibiotics exactly as prescribed. Skipping doses can lead to the infection not being fully treated and contribute to antibiotic resistance.

Do Not Stop Early

Even if you feel better, do not stop taking antibiotics until the prescribed course is complete. Stopping early can allow bacteria to survive and become resistant.

Avoid Sun Exposure

Some antibiotics can make your skin more sensitive to sunlight, leading to sunburn. Limit your sun exposure and use sunscreen when outdoors.

Do Not Take with Certain Foods and Drinks

Dairy products, acidic foods, and certain supplements can interfere with the absorption of some antibiotics. Consult your doctor or pharmacist about food interactions.

Avoid Sharing Antibiotics

Never share antibiotics with others or use leftover antibiotics. Antibiotics are prescribed for specific infections and dosages; using them inappropriately can be harmful.

Do Not Use Expired Antibiotics

Using expired antibiotics can be ineffective and even dangerous. Always check the expiration date and dispose of outdated medications properly.

Avoid Heavy Physical Activity

Some antibiotics can increase the risk of tendon rupture, so avoiding strenuous physical activity while on these medications is wise.

Do Not Ignore Side Effects

Contact your healthcare provider immediately if you experience significant side effects like severe diarrhoea, allergic reactions, or any unusual symptoms.

Do Not Rely on Antibiotics for Viral Infections

Antibiotics do not work against viruses, such as those causing colds or the flu. Using them unnecessarily can contribute to antibiotic resistance.

Following these guidelines helps ensure that your antibiotic treatment is as effective and safe as possible. Always consult a healthcare professional for personalised advice and guidance regarding antibiotic use.
