Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about ASTRIX capsules.
It does not contain all the available information.
It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may need to read it again.
What ASTRIX is used for
ASTRIX 100 mg capsules is a low dose formulation of aspirin. It is different to regular or extra strength aspirin formulas that are used for pain and headache relief.
ASTRIX capsules contain tiny, enteric-coated pellets of aspirin. The coating on these specially designed pellets prevents the aspirin from being released in the stomach where it may cause stomach irritation. Instead, the pellets travel through to the lower intestines where the aspirin is released.
Aspirin, when it is taken in a low dose every day, helps to keep blood platelets from sticking together. In people who have previously had a heart attack or stroke this helps prevent the formation of blood clots, which could block an artery and reduce or stop blood flow. This is especially important as we grow older, because the passageways of our arteries can narrow due to fatty cholesterol build-ups on the artery walls.
Your doctor may have prescribed ASTRIX for another reason.
Ask your doctor if you have any questions about why ASTRIX has been prescribed for you.

How to take ASTRIX
How much to take
Your doctor or pharmacist will tell you how many capsules you will need to take each day. However, you will probably be told to take one ASTRIX 100 mg capsule once daily with food.
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How to take it
Swallow ASTRIX capsules whole with a full glass of water.
When to take it
Take ASTRIX at about the same time each day.
Taking ASTRIX at the same time each day will have the best effect. It will also help you remember when to take your medicine.
Take ASTRIX during or immediately after a meal. If you take ASTRIX on an empty stomach, it may cause stomach upset.
If you forget to take it
If it is almost time for your next dose (within 12 hours), 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.
How long to take it
ASTRIX capsules are used as prevention or protection against heart disease, and should only be taken under a doctor’s supervision. Your doctor may tell you that you may need to take ASTRIX for a long period of time.
Continue taking ASTRIX for as long as your doctor or pharmacist tells you to. You should visit your doctor on a regular basis to monitor your condition.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too much ASTRIX. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much ASTRIX, you may experience:
- nausea (feeling sick) and/or vomiting
- fast heartbeat
- breathing difficulties
- seizures (fits)
While you are taking ASTRIX
Things you must do
Tell any other doctors, dentists, and pharmacists who are treating you that you are taking ASTRIX.
If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that you are taking ASTRIX.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking ASTRIX. ASTRIX capsules need to be stopped about one week prior to surgery.
If you become pregnant while taking ASTRIX, tell your doctor or pharmacist.
Things you must not do
Do not give ASTRIX to anyone else, even if they have the same condition as you.
Do not take ASTRIX to treat any other complaints unless your doctor or pharmacist tells you to.
Do not stop taking ASTRIX, or lower the dosage, without checking with your doctor or pharmacist.
Things to be careful of
Be careful driving or operating machinery until you know how ASTRIX affects you. Aspirin generally does not cause any problems with your ability to drive a car or operate machinery, however there is a very slight chance that aspirin may cause dizziness, drowsiness or tiredness in some people.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking ASTRIX.
ASTRIX helps to prevent blood clots forming in most people, but may have unwanted side effects in some people.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- stomach upset including nausea (feeling sick), vomiting, heartburn, indigestion
These side effects are usually mild.
If any of the following happen, stop taking ASTRIX and tell your doctor immediately or go to Accident and Emergency Department at your nearest hospital:
- vomiting blood or material that looks like coffee grounds
- bleeding from your back passage (rectum), black sticky motions or bloody diarrhoea
- swelling of the face, lips or tongue which may make swallowing or breathing difficult
- asthma, wheezing, shortness of breath
- sudden or severe itching, skin rash, hives
- pain or tightness in the chest.
These are very serious side effects. You may need urgent medical attention or hospitalisation.
All of these side effects are very rare.
Other side effects not listed above may occur in some patients.
Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
After using ASTRIX
Keep your capsules in the pack until it is time to take them. If you take the capsules out of the pack they will not keep well.

Keep ASTRIX where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor or pharmacist tells you to stop taking ASTRIX or the capsules have passed their expiry date, ask your pharmacist what to do with any that are left over.
