What DIASP SR is used for
DIASP SR helps to prevent recurrence of stroke in people who have had a previous stroke or transient ischaemic attack (TIA).
DIASP SR works by preventing blood clots from forming. The ability of DIASP SR to prevent blood clots is due to its effect on blood cells known as platelets.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason

How to take DIASP SR
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 box, ask your doctor or pharmacist for help.
How much to take
The recommended dose for adults is one capsule twice a day.
In some cases you may experience headache when you first start DIASP SR at the recommended dose. See your doctor if this occurs.
Your doctor may then change your dose for about one week. The changed dose will be one DIASP SR capsule at bedtime and low dose aspirin (for example, aspirin 75 mg, 100 mg or 150 mg) in the morning. After this time, your doctor will put you back onto your normal dose.
When to take it
Take your medicine at about the same time each day, usually one in the morning and one in the evening, and preferably with meals. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Swallow the capsule whole without chewing with a full glass of water.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
DIASP SR helps control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well. Therefore you must take DIASP SR every day.
If you forget to take it
If you miss a dose, take it as soon as you remember. However, if you remember when it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
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 (telephone 13 11 26) for advice, or go to Emergency at the nearest hospital, if you think that you or anyone else may have taken too much DIASP SR.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Signs of overdose may include feeling warm, flushing, sweating, restlessness, dizziness, weakness, rapid breathing, ringing in the ears, nausea, vomiting, vision and hearing disturbances and confusion. There may be effects on the heart and circulation causing chest pain, an increase in heart rate and a drop in blood pressure. In severe overdose, symptoms may include severe mental confusion, shaking, difficulty in breathing, sweating, bleeding, dehydration, reduced body temperature and coma.
