Can You Take Amoxicillin and Alcohol Together?
No, you should not take amoxicillin and alcohol together. While it isn’t as dangerous as mixing alcohol with some other medications, drinking while on a course of amoxicillin can make side effects worse, slow down your recovery, and put unnecessary strain on your body at a time when it needs to be working hard to fight infection. It’s best to wait until you’ve finished your full course before drinking.

What is Amoxicillin?
Amoxicillin is an antibiotic from the penicillin family, used to treat a wide range of bacterial infections. It works by stopping bacteria from growing, which gives your immune system the chance to clear the infection. It won’t do anything for viral infections like colds or flu, but it’s one of the most commonly prescribed antibiotics in the world and is considered safe for most people, including children and pregnant women.
It’s sold under brand names including Amoxil, Trimox, Moxilin, and Moxatag. Your doctor may sometimes prescribe it alongside other antibiotics, such as clarithromycin, particularly for stomach ulcers. One thing worth knowing: amoxicillin can reduce the effectiveness of the contraceptive pill, so speak to your doctor if this applies to you.
Warning: Only take amoxicillin when prescribed by a doctor for an actual infection. Taking it unnecessarily can make it less effective when you really need it.

Amoxicillin treats a broad range of bacterial infections. Below is a summary of the most common ones:
| Infection Type | Examples |
|---|---|
| Respiratory | Pneumonia, bronchitis, throat infections |
| Ear & Eye | Ear infections, eye infections |
| Urinary | Urinary tract infections (UTIs) |
| Other | Lyme disease, skin anthrax, chlamydia (in pregnancy) |
How Do You Take Amoxicillin?
You take amoxicillin three times a day, every eight hours, in the dose your doctor or pharmacist has prescribed. It comes in several forms: capsules, chewable tablets, liquid, and paediatric drops.
Capsules should be swallowed with a full glass of water, chewable tablets need to be thoroughly chewed before swallowing, and liquid forms should always be well shaken before use. Paediatric drops can be mixed into milk, fruit juice, or baby formula and should be taken immediately once mixed.
Always complete the full course, even if you start feeling better before it’s finished. Stopping early can allow the infection to return. If you miss a dose, take it as soon as you remember, but never double up to make up for a missed one.
Warning: The tendency and temptation to stop taking the drug once you feel better or symptoms disappear. However, it is recommended that you finish taking Amoxicillin as prescribed by your doctor until you are entirely done with the process.
Who Should Avoid Taking Amoxicillin?
Most people can take amoxicillin safely, but there are some groups who should speak to their doctor first. People with a known allergy to penicillin or any related antibiotic such as cephalosporin should not take it. Those with kidney disease or intestinal conditions may need an alternative, as the drug can put extra strain on those organs.
While amoxicillin is classified as safe during pregnancy (FDA Category B), your doctor should always be informed before you take it while pregnant or breastfeeding. Nursing mothers should also be aware that the drug can pass to a baby through breast milk, though serious effects are rare.
If you’re currently on other medications, including anticoagulants, allopurinol, probenecid, oral contraceptives, or other antibiotics, make sure your doctor knows. They may need to adjust your dose or consider a different treatment.
What Are the Side Effects of Amoxicillin?
The most common side effects of amoxicillin are mild and usually clear up on their own. These include nausea, diarrhoea, stomach pain, and oral or vaginal thrush. If any of these persist, it’s worth getting in touch with your doctor.
Some side effects are more serious and need immediate attention. Contact your doctor straight away if you experience severe abdominal cramps, difficulty breathing, swelling of the face, lips, or tongue, hives, seizures, unusual bleeding, or bloody diarrhoea. These can be signs of a serious allergic reaction and should not be left untreated.
Some side effects can be severe and cause serious discomfort: If you experience these, you should call the doctor immediately without wasting time. They include;
- Nausea
- Spasms (could be jaw, neck or back muscle)
- Severe abdominal cramps
- Shortness of breath
- Swelling of the lips, face or tongue
- Hives
- Unusual bleeding or bruising
- Seizures
- Fainting
- Bloody diarrhoea
These symptoms could represent severe allergic reactions to Amoxicillin, and you are encouraged to contact your doctor and make a complaint immediately.
Why Can't You Take Amoxicillin and Alcohol Together?
You shouldn’t take amoxicillin and alcohol together because, even though they don’t have a directly dangerous interaction, alcohol can make the side effects of amoxicillin significantly worse and actively slow down your recovery. The combination can cause nausea, headaches, fatigue, and dehydration, all of which compound each other and make you feel a lot worse than you need to.
Alcohol also affects how quickly it’s absorbed into your bloodstream. Amoxicillin can cause alcohol to be reabsorbed more rapidly, which may lead to stronger intoxication than you’d normally expect from the same amount. On top of that, both alcohol and antibiotics are processed by the liver, so combining them puts extra pressure on an organ that’s already working hard while your body fights infection.
The more important issue is what alcohol does to your immune system. Alcohol reduces the production of white blood cells, which are the cells your body relies on to fight off infection. So even if alcohol doesn’t directly stop amoxicillin from working, it undermines your body’s ability to make use of it. You end up working against the very thing you’re trying to do.
What Happens If You Take Amoxicillin and Alcohol Together?
If you drink alcohol while taking amoxicillin, you are likely to experience worsened side effects including nausea, vomiting, rapid heart rate, headaches, fatigue, and stronger than usual intoxication. These effects aren’t typically life-threatening, but they can be very unpleasant and extend the time it takes to recover from your infection.
The more significant concern is the impact on your immune system. Because alcohol lowers white blood cell production, your body is less equipped to fight the infection even with antibiotics on board. You might finish your course and still find that recovery takes longer than expected, simply because alcohol was working against your immune system throughout.
To Sum Up
No, you should not drink alcohol while taking amoxicillin. While the interaction isn’t outright dangerous, it can worsen side effects, slow your recovery, and reduce your immune system’s ability to fight the infection you’re trying to clear. The safest thing to do is wait until you’ve finished the full course before drinking.
