Dosage and how to take dipyridamole
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.
