What is the most important information I should know about dipyridamole?

Before taking dipyridamole, tell your doctor if you have liver disease, low blood pressure, coronary artery disease, angina (chest pain), or if you have recently had a heart attack.

Dipyridamole is often taken together with other medications to prevent blood clots. To best treat your condition, use all of your medications as directed by your doctor. Be sure to read the medication guide or patient instructions provided with each of your medications. Do not change your doses or medication schedule without advice from your doctor.

To be sure this medication is not causing harmful effects, your doctor may need to check your progress on a regular basis. Do not miss any scheduled visits to your doctor.

While you are taking dipyridamole, do not take aspirin or other NSAIDs (non-steroidal anti-inflammatory drugs) without your doctor's advice. NSAIDs include ibuprofen (Motrin, Advil), naproxen (Aleve, Naprosyn), diclofenac (Voltaren), diflunisal (Dolobid), etodolac (Lodine), flurbiprofen (Ansaid), indomethacin (Indocin), ketoprofen (Orudis), ketorolac (Toradol), mefenamic acid (Ponstel), meloxicam (Mobic), nabumetone (Relafen), piroxicam (Feldene), and others.

There may be other drugs that can affect dipyridamole. During your treatment with dipyridamole, you may also be taking another blood thinner such as warfarin (Coumadin). There are many drugs that can interact with blood thinners.

Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.

What is dipyridamole?
