Alcohol and Amoxicillin: Can You Drink While on Medication?

Amoxicillin is a widely prescribed antibiotic in the United States that treats many bacterial infections. At the same time, alcohol remains the most commonly abused substance. Many people wonder if it’s safe to mix the two.


This is important because a study showed that over 40% of adults had taken medications in the past year that could react with alcohol. Since many drugs, including antibiotics like amoxicillin, can react with alcohol, it’s important to understand the potential risks.

Alcohol and Amoxicillin Overview

Can You Drink Alcohol with Amoxicillin?

The short answer is, yes, however it’s not advisable to drink alcohol while taking amoxicillin. While it is less dangerous to drink alcohol with amoxicillin compared to many other drugs, it’s still recommended to avoid alcohol.


Alcohol doesn’t directly interfere with amoxicillin but can affect how your body processes it. This can potentially lead to undesired consequences, such as reducing the effectiveness of the antibiotic or increasing side effects. Therefore, it’s important to understand how amoxicillin works and the possible interactions with alcohol.

Understanding Amoxicillin

What Is Amoxicillin?

Amoxicillin, sometimes known as Amoxil, is an antibiotic that belongs to the penicillin family. It is commonly used to treat various bacterial infections, including those affecting the ears, nose, skin, urinary tract, lungs, and throat. Patients can take amoxicillin as extended-release or immediate-release tablets. These tablets can be chewed or swallowed, depending on the patient’s preference. Typically, amoxicillin comes in dosages of 500 mg or 875 mg, and it is taken every 8 to 12 hours with food to enhance absorption and reduce stomach upset.

What Is Amoxicillin Used For?

Amoxicillin is prescribed to treat a wide range of bacterial infections. It is effective against chest infections, such as pneumonia, and dental abscesses. Additionally, it can be combined with other antibiotics and medications to treat stomach ulcers. Amoxicillin is frequently prescribed for children to address ear and chest infections. It is available by prescription only and comes in capsules or liquid form for oral administration. In some cases, it can be given by injection, but this is typically done in a hospital setting.

Amoxicillin Side Effects

Short Term Effects of Amoxicillin

Amoxicillin can cause a variety of short-term side effects that vary in severity depending on an individual’s sensitivity to the drug. Some common short-term side effects include:

    • Vomiting
    • Diarrhea
    • Vaginal discharge
    • Rashes
    • Black, swollen, hairy tongue
    • Stomach pain
    • Dizziness
    • Headache
    • Yeast infections
    • Nausea

These effects are generally mild to moderate and usually disappear within days or weeks. However, side effects like diarrhea can lead to dehydration, especially if combined with alcohol, which also causes dehydration. Headaches can increase irritability and distract patients from daily activities, a condition worsened by alcohol consumption.

Long Term Effects of Amoxicillin

In some cases, long-term use of amoxicillin can result in more serious side effects. These may include:

    • Breathing problems
    • Problems urinating
    • Seizures
    • Allergic reactions
    • Dark urine
    • Bruising and abnormal bleeding
    • Asthma
    • Menstrual problems
    • Jaundice
    • Liver damage
    • Flu-like symptoms
    • Open sores from blisters

Long-term effects can worsen with frequent use of the medication. Mixing amoxicillin with other medications or alcohol can cause more complex symptoms. People with conditions like diabetes or kidney disease face extra risks, like dark urine or worsening kidney issues. Other potential long-term effects include brain fog, depression, hallucinations, and psychotic disorders, especially when amoxicillin is combined with clarithromycin.

Consumption Guidelines for Amoxicillin

Dosage Forms and How to Take Amoxicillin

Generic amoxicillin is available in several oral forms, including capsules, chewable tablets, tablets, and liquid suspensions. This variety makes it easier for patients of all ages to take the medication.


To ensure the best results, try to space your doses evenly throughout the day. For instance, if you need to take amoxicillin three times a day, consider doing so in the morning, mid-afternoon, and at bedtime. You can take amoxicillin either before or after meals, depending on what suits you best.


If you are taking amoxicillin capsules, swallow them whole with a drink of water. Avoid chewing or breaking the capsules. For children or individuals who have difficulty swallowing pills, amoxicillin is also available in liquid form. This liquid medication is usually prepared by a pharmacist and comes with a plastic syringe or spoon to help measure the correct dose. If you do not have a syringe or spoon, ask your pharmacist for one, as using a kitchen teaspoon might not provide the accurate dosage.


Proper dosage and administration are crucial for effective treatment and to prevent antibiotic resistance. Always follow your healthcare provider’s instructions and complete the full course of the medication, even if you start to feel better before it is finished. This ensures that the infection is fully treated and reduces the risk of recurrence.

Brand-Name Variations of Amoxicillin

Amoxicillin is commonly available in generic form. However, it is also present in various brand-name products, either as the sole ingredient or combined with other medications. Some popular brand-name variations include:


    • Amoxil (amoxicillin)
    • Talicia (omeprazole/amoxicillin/rifabutin)
    • Augmentin (amoxicillin/clavulanate)

Alcohol And Amoxicillin

Alcohol can weaken your immune system, making it harder for your body to fight off infections. That’s why doctors usually advise against drinking alcohol while taking amoxicillin.

However, if you drink a lot of alcohol while on amoxicillin, it can lead to serious reactions like blackouts, aggressive behavior, and increased toxicity.

Mixing alcohol with amoxicillin strains your liver, which has to process both.

How Long After Taking Amoxicillin Can You Drink Alcohol?

After finishing a course of amoxicillin, it’s important to give your body time to recover. The side effects of the medication and the infection itself can leave you feeling run down.


Drinking alcohol soon after taking amoxicillin can worsen side effects and slow healing. It’s best to wait at least 72 hours after finishing your course of amoxicillin before drinking alcohol. This waiting period allows your body to fully recover from both the infection and the effects of the medication.

Factors That Affect Alcohol Consumption Timing

Several factors can influence how soon you can safely drink alcohol after taking amoxicillin. These include your overall health, the severity of the infection, and how your body responds to the antibiotic. Always consider consulting your healthcare provider for personalized advice based on your specific situation.

What Happens When Amoxicillin and Alcohol Combine?

While alcohol doesn’t directly interact with amoxicillin, it can affect how your body processes the medication, leading to unwanted consequences. The liver processes both alcohol and antibiotics, and having both in your system can strain the liver, affecting its ability to function well. Here are some potential risks:


    • Reduced Antibiotic Effectiveness: Drinking alcohol while taking amoxicillin can compromise the antibiotic’s effectiveness. Alcohol can interfere with your immune response, making it harder for your body to fight the infection. This can delay healing and might cause the infection to persist or worsen.
    • Increased Side Effects: Amoxicillin can cause side effects like nausea, vomiting, diarrhea, and stomach cramps. Alcohol can intensify these effects, making them more severe and uncomfortable.
    • Liver Strain: The liver metabolizes both alcohol and amoxicillin. Taking both can overload the liver, leading to liver toxicity and damage, especially in those with pre-existing liver conditions.
    • Central Nervous System Problems: Both alcohol and amoxicillin can depress the central nervous system, causing dizziness, drowsiness, and reduced coordination. This can be dangerous, especially when driving or operating machinery.
    • Gastrointestinal Distress: Both substances can irritate the gastrointestinal lining. Together, they can cause significant discomfort, including nausea, vomiting, diarrhea, and stomach cramps.
    • Increased Risk of Medication Non-Compliance: Alcohol can impair judgment and decision-making, leading to missed doses or incorrect usage of the antibiotic, hindering effective treatment.


If you have been prescribed amoxicillin and are unsure about consuming alcohol, consult your healthcare provider. They can offer advice based on your medical history and specific treatment plan. Following their guidance ensures the best possible outcome for your health and recovery.

Finding Help and Support

Fighting a substance use disorder or mixing medications with other chemicals can be dangerous. If you or a loved one cannot reduce use or is tempted to mix medications, it can be harmful. You may have a substance use disorder without realizing it. Contact a treatment provider who can discuss options with you. Treatment facilities offer a safe space for individuals to heal with counseling, peer groups, and medications. Seeking help is a crucial step towards recovery and overall health.
