The recommended oral adult dose of dipyridamole for preventing blood clots is 100 mg 4 times daily one hour before meals. If taken with 1000 mg of Asa daily, the dose of dipyridamole can be reduced to 25 mg 4 times daily.

When used for medical tests that examine how well blood is flowing through the heart, dipyridamole is given by injection in a hospital.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Dipyridamole exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Dipyridamole at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
