How And When To Take Dipyridamole

How much dipyridamole you take depends on what form you have been prescribed. Always follow your doctor's instructions.

Dosage

The usual dose of dipyridamole for slow-release capsules is 200mg, taken twice a day.

The usual dose for tablets and liquid is 300mg to 600mg a day, divided into 3 or 4 smaller doses.

For children, a doctor will use your child's weight to work out the right dose. Children usually need to take it 2 or 3 times a day.

How to take slow-release capsules

Slow-release capsules release the medicine slowly in your body over several hours. You'll usually take 1 capsule in the morning and 1 capsule in the evening.

Take your capsules with or soon after a meal. Swallow them whole with a drink of water. Do not crush or chew them.

Capsules are not prescribed for children.

How to take tablets or liquid

If you're taking tablets or liquid, your doctor will tell you whether to take your dose 3 or 4 times a day. Take it before meals and try to stick to the same times each day. Swallow the tablet whole with a drink of water.

The liquid dipyridamole will come with a syringe or spoon to help you measure out the right dose. If you do not have a syringe or spoon, ask your pharmacist for one. Do not use a kitchen teaspoon because it will not measure the right amount.

How long to take it for

You'll usually need to take dipyridamole for the rest of your life. Do not stop taking it without talking to your doctor.

If you stop taking dipyridamole, your blood will go back to clotting at the rate it did before. This usually happens within 2 days of stopping the medicine. This means you may be at increased risk of serious problems like heart attacks or strokes.

If you forget to take it

If you forget a dose of dipyridamole, take it as soon as you remember, unless it's nearly time for your next dose. In this case, skip the missed dose and take the next dose at the usual time.

Never take 2 doses at the same time. Never have an extra dose to make up for a forgotten dose.

If you often forget doses, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicines.

If you take too much

The amount of dipyridamole that can lead to overdose is different from person to person.
