- other antibiotics (e.g. tetracyclines)
- the contraceptive pill. As with other antibiotics you may need to use extra birth control methods (e.g. condoms)
- anticoagulants, used to prevent blood clots (e.g. warfarin)
These medicines may be affected by amoxicillin or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines.

How to take this medicine
Follow all directions from your doctor or pharmacist carefully. They may be different to the information in this leaflet.
If you do not understand any written instructions, ask your doctor or pharmacist for help.
How much to take
Your doctor or pharmacist will tell you how many capsules you will need to take. This depends on your condition and whether or not you are taking any other medicines.
The usual adult dose is one capsule (250 mg or 500 mg) three times a day.
For some infections 3 grams of amoxicillin (i.e. six 500 mg capsules) can be taken by adults at one time.
How to take it
Swallow amoxicillin capsules whole with a glass of fluid.
When to take it
Take it at about the same time each day. Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take it.
Space the doses as evenly as possible throughout the day. For example, if you are taking amoxicillin three times a day, take a dose about every eight hours.
Amoxicillin can be taken with or without food. The effects of amoxicillin are not changed by food.
How long to take it for
Continue taking amoxicillin until you finish the pack, or until your doctor says so.
Do not stop taking your capsules because you are feeling better. If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 for Australia) or go to the Accident and Emergency Department at the nearest hospital, if you think that you or anyone else may have taken too much amoxicillin.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much amoxicillin, you may feel sick or get diarrhoea.
