How to take amoxicillin
Zurück zum InhaltBefore you start the amoxicillin treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about amoxicillin and will provide you with a full list of the side effects you may experience from taking amoxicillin.
Take amoxicillin exactly as your doctor tells you to. It is usually taken three times daily, every eight hours. Your dose will be different to this if you are being treated with sachets of amoxicillin powder, or if you are taking amoxicillin to treat a stomach ulcer.
Your doctor or pharmacist will tell you how you should take the medication, and this information will be printed on the label of the pack to remind you.
It is important that you space out the amoxicillin doses evenly during the day.
If you have been given liquid medicine for a child, read the directions carefully to make sure you measure out the correct amount of medicine.
You can take amoxicillin either with or without food. The amoxicillin capsules should be swallowed whole with a drink of water.
If you have been supplied amoxicillin oral powder sachets, stir the powder from the sachet into 10-20 ml of water. Drink the solution as soon as possible after mixing it.
If you forget to take a dose of amoxicillin at the correct time, take one as soon as you remember. Try to take the correct number of doses each day, leaving at least four hours between doses. Do not take two doses of amoxicillin at the same time to make up for a missed dose.
Das Beste aus Ihrer Behandlung herausholen
Zurück zum InhaltIf you (or your child) have been prescribed the oral liquid amoxicillin medicine, you may find that it causes some staining of the teeth. Brushing the teeth regularly helps to prevent this. Any staining usually disappears soon after the course of antibiotics is finished.
Even if you feel your infection has cleared up, keep taking the antibiotic until the course is finished (unless a doctor tells you to stop). This is to prevent the infection from coming back.
Antibiotics are prescribed in short courses of treatment. Your doctor will tell you how long your course of treatment will last - this is not usually for longer than 14 days. If you still feel unwell after finishing the course, go back to see your doctor.
Some people develop redness and itching in the mouth or vagina (thrush) after taking a course of antibiotics. If this happens to you, speak with your doctor or pharmacist for advice.
If you are taking birth control like the contraceptive 'pill' at the same time as this antibiotic, the effectiveness of the 'pill' can be reduced if you have a bout of being sick (vomiting) or diarrhoea which lasts for more than 24 hours.
If this should happen, ask your doctor or pharmacist for advice about what additional contraceptive precautions to use over the following few days.
There is no need to use additional precautions for any bouts of sickness or diarrhoea which last for less than 24 hours.
Amoxicillin can stop the oral typhoid vaccine from working so if you are due to have any vaccinations, make sure the person treating you knows that you are taking this antibiotic.

Häufig gestellte Fragen
Zurück zum InhaltCan you drink alcohol with amoxicillin?
You can usually drink alcohol in moderation while taking amoxicillin, as it does not interact directly with the medicine. However, alcohol can make side effects such as nausea, dizziness, and stomach upset more likely, and may slow your recovery. If you are feeling unwell, it is generally best to avoid alcohol until you are better.
Can you take paracetamol with amoxicillin?
Yes, you can take paracetamol with amoxicillin. The two medicines do not interact, and paracetamol can help relieve fever or pain while the antibiotic treats the infection. Always follow the dosing instructions on the label or from your doctor.
Can amoxicillin make you tired?
Amoxicillin itself does not usually cause tiredness, but some people do feel more fatigued while taking it. This is often due to the infection your body is fighting rather than the antibiotic.
Does amoxicillin treat UTIs?
Amoxicillin can be used to treat some urinary tract infections, but it is not always the first choice. Many UTIs are caused by bacteria that are resistant to amoxicillin, so doctors often prescribe other antibiotics instead. A urine test is usually needed to confirm the best treatment.
