Dipyridamole is sometimes used together with an anticoagulant (blood thinner) or aspirin. The combination of medicines may provide better protection against the formation of blood clots than any of the medicines used alone. However, the risk of bleeding may also be increased when dipyridamole is taken with aspirin. To reduce the risk of bleeding:
Do not take aspirin, or any combination medicine containing aspirin, unless the same doctor who directed you to take dipyridamole also directs you to take aspirin. This is especially important if you are taking an anticoagulant together with dipyridamole.
If you have been directed to take aspirin together with dipyridamole, take only the amount of aspirin ordered by your doctor . If you need a medicine to relieve pain or a fever, your doctor may not want you to take extra aspirin. It is a good idea to discuss this with your doctor, so that you will know ahead of time what medicine to take.
Your doctor should check your progress at regular visits.
Tell all medical doctors and dentists you go to that you are taking dipyridamole, and whether or not you are taking an anticoagulant (blood thinner) or aspirin together with it.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.
