1. About amoxicillin
Amoxicillin is an antibiotic. It’s used to treat bacterial infections, such as chest infections (including pneumonia), dental abscesses and urinary tract infections (UTIs).
It’s used in children, often to treat ear infections and chest infections. The medicine is only available on prescription. It comes as capsules or as a liquid that you drink. It’s also given by injection, but this is usually only done in hospital.
2. Belangrijkste feiten
- 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 doesn’t last and is removed by brushing.
- You can drink alcohol while taking amoxicillin.
- Amoxicillin is also called by the brand name Amoxil.
3. Who can and cannot take amoxicillin
Amoxicillin can be taken by adults, including pregnant and breastfeeding women. Amoxicillin can be taken by children.
Amoxicillin isn’t suitable for some people. To make sure amoxicillin is safe for you, tell your doctor if you:
- have had an allergic reaction to amoxicillin or penicillin or any other medicines in the past
- have liver or kidney problems
- have recently had, or are about to have, any vaccinations
4. Hoe en wanneer in te nemen?
The usual dose of amoxicillin is 250mg to 500mg taken 3 times a day. The dose may be lower for children.
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.
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
- 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 tablets.
- If you or your child are taking amoxicillin as a liquid, 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 don’t have one, ask your pharmacist for one. Do not use a kitchen teaspoon as it will not give the right amount.
Wat als ik het vergeet in te nemen?
- 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 as normal.
- Neem nooit 2 doses tegelijk. Neem nooit een extra dosis om een vergeten dosis in te halen.
- 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.
Wat als ik te veel neem?
Accidentally taking an extra dose of amoxicillin is unlikely to harm you or your child. Speak to your pharmacist or doctor if you’re worried or you take more than 1 extra dose.
Like all medicines, amoxicillin can cause side effects, although not everyone gets them.

9. Veelgestelde vragen
How does amoxicillin work?
Amoxicillin is a similar antibiotic to penicillin. 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 don't get better?
Tell your doctor if you don't 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. It happens because antibiotics kill the normal harmless bacteria that help to protect you against thrush. Ask your pharmacist or doctor for advice if this happens to you.
Heeft het invloed op mijn anticonceptie?
Amoxicillin doesn't stop contraceptive pills working, including the combined pill or emergency contraception. However, if amoxicillin makes you vomit or have severe diarrhoea (6 to 8 watery poos in 24 hours) for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Look on the pill packet to find out what to do.
Zal het mijn vruchtbaarheid beïnvloeden?
There's no firm evidence to suggest that taking amoxicillin will reduce fertility in either men or women. However, speak to a pharmacist or your doctor before taking it if you're trying to get pregnant.
Does it stain teeth?
If you or your child take amoxicillin as a liquid medicine, it can stain your teeth. This doesn't last and should go after brushing your teeth well. Amoxicillin capsules don't stain teeth.
Mag ik autorijden of fietsen?
Yes, amoxicillin shouldn't 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.
Kan ik er alcohol bij drinken?
Yes, you can drink alcohol with amoxicillin.
Can lifestyle changes help urinary tract infections?
It's possible that a straightforward urinary tract infection (UTI) may clear up on its own without any treatment. However, it's usually best to treat a UTI with an antibiotic, or it could spread to the kidneys and lead to more serious problems.
Once treated, there are steps you can take to stop UTIs coming back:
-do not use perfumed bubble bath, soap or talcum powder around your genitals – use plain, unperfumed products, and have a shower rather than a bath
-go to the toilet as soon as you need to pee and always empty your bladder fully
-stay well hydrated – aim to drink 6 to 8 glasses of fluid a day (water, lower-fat milk and sugar-free drinks, including tea and coffee, all count)
-wipe your bottom from front to back when you go to the toilet
-empty your bladder as soon as possible after having sex
-do not use a contraceptive diaphragm or condoms with spermicidal lubricant on them – use another type of contraception instead
-wear underwear made from cotton, rather than synthetic material like nylon, and avoid tight jeans and trousers
Although they won't do any harm, there's little evidence to show drinking cranberry juice or taking cranberry supplements helps treat or prevent UTIs.
