Amoxicillin: antibiotic to treat bacterial infections

1. About amoxicillin

Amoxicillin is a penicillin antibiotic. It is used to treat bacterial infections, such as chest infections (including pneumonia) and dental abscesses. It can also be used together with other antibiotics and medicines to treat stomach ulcers.

It’s often prescribed for children, to treat ear infections and chest infections.

Amoxicillin is only available on prescription. It comes as capsules or as a liquid that you swallow. It’s also given by injection, but this is usually only done in hospital.

2. Key facts

• For most infections, you’ll start to feel better in a few days.
• The most common side effects of amoxicillin are feeling sick (nausea) and diarrhoea.
• Liquid amoxicillin can stain your teeth. This does not last and is removed by brushing.
• You can drink alcohol while taking amoxicillin.
• Sometimes, taking amoxicillin can cause thrush.

3. Who can and cannot take amoxicillin

Amoxicillin can be taken by most adults and children.

Find out more about giving amoxicillin to children on the Medicines for Children website.

Amoxicillin is not suitable for everyone. To make sure amoxicillin is safe for you, tell your doctor if you:

• have ever had an allergic reaction to amoxicillin or penicillin or any other medicine
• have liver or kidney problems
• have recently had, or are due to have, any vaccinations

4. How and when to take amoxicillin

Dosage

The usual dose of amoxicillin capsules is 250mg to 500mg, taken 3 times a day. The dose may be lower for children.

Amoxicillin liquid is available in 125mg and 250mg doses.

Important

Carry on taking this medicine until you’ve completed the course, even if you feel better. If you stop your treatment early, the infection could come back.

How to take it

Try to space the doses evenly throughout the day. If you take it 3 times a day, this could be first thing in the morning, mid-afternoon and at bedtime.

You can take amoxicillin before or after food.

Swallow amoxicillin capsules whole with a drink of water. Do not chew or break them.

Amoxicillin is available as a liquid for children and people who find it difficult to swallow capsules.

If you or your child are taking liquid amoxicillin, it will usually be made up for you by your pharmacist. The medicine will come with a plastic syringe or spoon to help you measure out the right dose. If you do not have one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not measure the right amount.

If you forget to take it

If you forget to take a dose, take it as soon as you remember, unless it’s nearly time for your next dose. In this case, just leave out the missed dose and take your next dose at the usual time.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to remember your medicines.

If you take too much

Taking an extra dose of amoxicillin is unlikely to harm you or your child, but speak to your pharmacist or doctor if you’re worried.

Urgent advice: Contact 111 for advice now if:

You have taken more than your prescribed dose of amoxicillin and have symptoms including:

• stomach pain or you’re being sick
• blood in your pee
• difficulty peeing or producing less pee than usual

Go to 111.nhs.uk or call 111

5. Side effects

Like all medicines, amoxicillin can cause side effects, although not everyone gets them.

Common side effects

These common side effects happen in around 1 in 10 people. Keep taking the medicine, but talk to your doctor or pharmacist if these side effects bother you or do not go away:

• feeling sick (nausea)
• diarrhoea

Serious side effects

Serious side effects are rare and happen in less than 1 in 1,000 people.

Call a doctor or call 111 now if you get:

• diarrhoea (possibly with stomach cramps) that contains blood or mucus or severe diarrhoea that lasts for more than 4 days
• pale poo and dark pee, and the whites of your eyes or your skin turn yellow (although this may be less obvious on brown or black skin) – these can be signs of liver or gallbladder problems
• bruising or changes in your skin colour
• joint or muscle pain that comes on after 2 days of taking the medicine
• a skin rash with circular red patches (this may be less obvious on brown or black skin)

Some of these serious side effects can happen up to 2 months after finishing the amoxicillin.

Serious allergic reaction

Around 1 in 15 people have an allergic reaction to amoxicillin.

In most cases, the allergic reaction is mild and can take the form of a skin rash.

Mild skin rashes can usually be treated by taking antihistamines.

In rare cases, amoxicillin can cause a serious allergic reaction (anaphylaxis).

Immediate action required: Call 999 now if:

• your lips, mouth, throat or tongue suddenly become swollen
• you’re breathing very fast or struggling to breathe (you may become very wheezy or feel like you’re choking or gasping for air)
• your throat feels tight or you’re struggling to swallow
• your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
• you suddenly become very confused, drowsy or dizzy
• someone faints and cannot be woken up
• a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)

You or the person who’s unwell may also have a rash that’s swollen, raised, itchy, blistered or peeling.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.

These are not all the side effects of amoxicillin. For a full list, see the leaflet inside your medicines packet.

Information:

You can report any suspected side effect using the Yellow Card safety scheme.

Visit Yellow Card for further information.

6. How to cope with side effects of amoxicillin

What to do about:

• feeling sick – stick to simple meals and do not eat rich or spicy food. It might help to take your amoxicillin after a meal or snack.
• diarrhoea – drink plenty of fluids, such as water or squash, to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor. If you take contraception and you have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Check the pill packet to find out what to do.

7. Pregnancy and breastfeeding

Amoxicillin and pregnancy

It is safe to take amoxicillin during pregnancy.

Amoxicillin and breastfeeding

It is OK to take amoxicillin while breastfeeding. Information shows that only tiny amounts of amoxicillin get into breast milk. Such levels would not be expected to cause side effects in your baby.

Talk to your doctor, pharmacist, health visitor or midwife if:

• your baby is not feeding as well as usual
• they have sickness or diarrhoea
• your baby has oral thrush, or a skin rash
• you have any other concerns about your baby

For more information about how amoxicillin can affect you and your baby during pregnancy, visit the Best Use of Medicines in Pregnancy (BUMPS) website.

8. Cautions with other medicines

There are some medicines that do not mix well with amoxicillin.

Tell your doctor if you’re taking any of these medicines before you start taking amoxicillin:

• methotrexate, used to treat arthritis and psoriasis
• warfarin, a medicine to prevent blood clots
• gout medicines called probenecid or allopurinol
• other antibiotics

Tell your doctor if you’ve recently had, or are due to have, an oral typhoid vaccine. Amoxicillin can make it less effective.

Mixing amoxicillin with herbal remedies and supplements

There is little information about taking herbal remedies and supplements alongside amoxicillin.

Important:
Medicine safety

Tell your doctor or pharmacist if you’re taking any other medicines, including herbal medicines, vitamins or supplements.

9. Common questions about amoxicillin

How does amoxicillin work?

Amoxicillin is a penicillin antibiotic. It works by killing the bacteria that cause the infection.

When will I feel better?

For most infections, you should feel better within a few days.

It’s very important that you keep taking amoxicillin until your course is finished. Do this even if you feel better. It will help stop the infection coming back.

What if I do not get better?

Tell your doctor if you do not start feeling better after taking amoxicillin for 3 days. Also tell them if, at any time, you start to feel worse.

Will it give me thrush?

Some people get a fungal infection called thrush after taking a course of antibiotics like amoxicillin. If you think you have thrush, speak to your pharmacist or ask your doctor for advice.

How does amoxicillin compare with other antibiotics?

Amoxicillin and other penicillins, like phenoxymethylpenicillin, are antibiotics that are widely used to treat a variety of infections, including skin, dental, throat and chest infections.

Not all antibiotics are suitable for every infection. Your doctor will choose an antibiotic that’s suitable for the type of infection you have. Speak to your pharmacist or doctor if you have any questions.

Will it affect my contraception?

Amoxicillin does not stop contraceptive pills working, including the combined pill or emergency contraception.

However, if amoxicillin makes you sick (vomit) or have severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Check the pill packet to find out what to do.

Find about more about what to do if you’re on the pill and you’re being sick or have diarrhoea.

Will it affect my fertility?

There’s no evidence to suggest that taking amoxicillin reduces fertility in either men or women.

Does it stain teeth?

If you or your child take amoxicillin as a liquid medicine, it can stain your teeth. This does not last and should go after brushing your teeth well.

Amoxicillin capsules do not stain teeth.

Can I drive or ride a bike?

Yes. Amoxicillin should not affect you being able to drive or cycle.

Is there any food or drink I need to avoid?

You can eat and drink normally while taking amoxicillin.

Can I drink alcohol with it?

Yes, you can drink alcohol with amoxicillin.

Amoxicillin oral tablet can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.

To help avoid interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking.

To find out how this drug might interact with something else you’re taking, talk with your doctor or pharmacist.

Examples of drugs that can cause interactions with amoxicillin are listed below.

Drugs that increase the risk of side effects from amoxicillin

Taking amoxicillin with certain medications raises your risk of side effects from amoxicillin. This is because the amount of amoxicillin in your body may be increased. Examples of these drugs include:

• Probenecid: Taking probenecid with amoxicillin could lead to increased blood levels of amoxicillin. A doctor may need to decrease the dose of amoxicillin in some patients.
• Allopurinol: If you use allopurinol and amoxicillin together, you may develop a rash.

Interactions that increase the risk of side effects from other drugs

Taking amoxicillin with certain medications raises your risk of side effects from these medications. Amoxicillin increases the amount of these drugs in your body.

Examples of these drugs include drugs to treat blood clots. These are called anticoagulants (or blood thinners) and include warfarin (Jantoven), apixaban (Eliquis), heparin, and others.

If you use these drugs with amoxicillin, you have a higher risk of bleeding. Your doctor may adjust your dose of amoxicillin as a result.

Interactions that can make your drugs less effective

When amoxicillin is less effective: When amoxicillin is used with certain drugs, it may not work as well. In vitro studies have shown potential interactions that can cause the amount of amoxicillin in your body may be decreased.

Because in vitro studies are only conducted in a lab and not on live subjects, it is not clear whether this can significantly impact you if you’re taking amoxicillin with these drugs.

Nevertheless, examples of these drugs include:

• Chloramphenicol
  • If you use these drugs together, your doctor will likely keep your dosage of amoxicillin the same.
• Macrolides, such as erythromycin, clarithromycin, or azithromycin
  • If you use these drugs together, your doctor will likely keep your dosage of amoxicillin the same.
• Sulfonamides, such as sulfamethoxazole
  • If you use these drugs together, your doctor will likely keep your dosage of amoxicillin the same.
• Tetracyclines, such as tetracycline or doxycycline
  • If you use these drugs together, your doctor will likely keep your dosage of amoxicillin the same.

When other drugs are less effective: When certain drugs are used with amoxicillin, they may not work as well. This is because the amount of these drugs in your body may be decreased. Examples of these drugs include:

• Oral contraceptives (birth control)
  • If you need to take amoxicillin, you should consider using a barrier method of birth control while on amoxicillin. Or, your doctor may prescribe a different form of birth control for you.

Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs interact differently in each person, we cannot guarantee that this information includes all possible interactions. This information is not a substitute for medical advice. Always speak with your healthcare professional about possible interactions with all prescription drugs, vitamins, herbs and supplements, and over-the-counter drugs that you’re taking.

This drug comes with several warnings.

Allergies

Amoxicillin can cause a severe allergic reaction. Symptoms can include:

Warnings for people with certain health conditions

For people with mononucleosis (mono or kissing disease): Amoxicillin raises your risk of developing a severe rash.

For people with diabetes: Amoxicillin may cause you to have a false-positive reaction when testing for glucose (sugar) in the urine. Talk with your doctor about how to manage your blood sugar while taking amoxicillin.

For people with kidney disease: If you have severe kidney disease, your kidneys may not clear this drug from your body quickly. As a result, levels of amoxicillin may build up in your body. To help prevent this, your doctor may give you a lower dose of this drug.

Warnings for other groups

For pregnant people: Research in animals has not shown adverse effects on the fetus when pregnant animals were exposed to amoxicillin. There haven’t been enough studies done on humans to be certain if the drug poses a risk to the fetus. However, you may want to still speak with your doctor if you’re pregnant or planning to become pregnant.

For people who are breastfeeding (nursing): Amoxicillin may pass into breast milk and may cause side effects in a child who is breastfed. Talk with your doctor if you are breastfeeding your child. You may need to decide whether to stop breastfeeding or stop taking this medication.

For older adults (ages 65 years and over): The kidneys of older adults may not work as well as those of younger adults. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.

Amoxicillin oral tablet is used for short-term treatment. It comes with serious risks if you don’t take it as prescribed.

What is amoxicillin?

Amoxicillin is an antibiotic belonging to the penicillin group. Its action is aimed at combating bacterial infections caused by microorganisms sensitive to it.

Amoxicillin is the first line of treatment for many infections of the upper and lower respiratory tract, urinary and gastrointestinal tract, and skin infections. Its effectiveness has been proven in studies and confirmed by many years of clinical experience.

• Amoxicillin penetrates the bacterial cell and destroys its wall, causing the death of the microorganism.

• Amoxicillin is considered relatively safe and well tolerated by most patients.

However, like all antibiotics, amoxicillin can cause side effects. When using it, you must follow the recommendations of the doctor and take it only as directed. It is not recommended to independently choose the dosage and duration of administration.

Action of amoxicillin

Amoxicillin is an antibiotic used to treat various infections caused by bacteria. It belongs to the penicillin class and works by blocking the ability of bacteria to build the walls they need to survive.

When amoxicillin enters the body, it begins to destroy the bacteria that cause the infection. It accesses the bacteria’s genetic material and blocks their ability to grow and reproduce. The drug also eliminates the symptoms of infection and helps protect the body from possible complications.

1. The effect of the drug is contraindicated for use in viral infections . Amoxicillin can only kill bacteria, so it won’t work if the infection is caused by a virus.
2. Amoxicillin binds to other drugs . When taking more than one drug therapy, the use of amoxicillin in combination with the use of other drugs should be clarified.
3. Amoxicillin should not be interrupted . Treatment of the infection should be carried out to the end, and one-time omissions can lead to the formation of drug-resistant species of microorganisms.

When to use amoxicillin:

Amoxicillin is an antibiotic used to treat infections caused by bacteria. Amoxicillin is recommended for use in cases where the patient has an acute illness such as pharyngitis, tonsillitis, bronchitis, pneumonia, cystitis, urinary tract infections, or skin infections.

In addition, amoxicillin can be used in the treatment of other diseases caused by bacteria. For example, it can help fight gonorrhea, ehrlichiosis, listeriosis, and yeast infections. However, before using amoxicillin, you should always consult your doctor and follow the recommendations of the instructions.

Amoxicillin may also be recommended for prophylactic use. For example, a doctor may advise taking it before a dental procedure to prevent infection. In such cases, the dosage and treatment regimen are determined individually depending on the disease and the characteristics of the patient’s body.

• Important to know! Never take amoxicillin without the advice of a doctor and strictly follow the instructions for use. Incorrect use of antibiotics can lead to bacterial resistance, making it difficult to treat in the future.
