Aggrenox (aspirin / dipyridamole) and Alcohol / Food Interactions

There are 3 alcohol/food/lifestyle interactions with Aggrenox (aspirin / dipyridamole) which include:

Moderate

dipyridamole ↔ Caffeine

Moderate Drug Interaction

Ask your doctor before using dipyridamole together with caffeine. Using these medications together can decrease the effects of dipyridamole. It is recommended that caffeine including caffeine be avoided for 12 to 24 hours before dipyridamole administration. You may need a dose adjustment or special test if you use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Minor

aspirin ↔ Caffeine

Minor Drug Interaction

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

For clinical details see professional interaction data.

Moderate

aspirin ↔ Alcohol (Ethanol)

Moderate Drug Interaction

Ask your doctor before using aspirin together with ethanol. Do not drink alcohol while taking aspirin. Alcohol can increase your risk of stomach bleeding caused by aspirin. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

ADJUST DOSING INTERVAL: Caffeine and other xanthine derivatives (e.g., theophylline) are nonspecific, competitive antagonists of adenosine receptors. As such, they may interfere with the vasodilating effect of dipyridamole, an adenosine receptor agonist. In studies of healthy volunteers, caffeine has been shown to reduce the hemodynamic response (i.e., heart rate increases, vasodilation, blood pressure changes) to dipyridamole infusions, and both caffeine and theophylline have been reported to cause false-negative results in myocardial scintigraphy tests using dipyridamole.

MANAGEMENT: Patients should avoid consumption of caffeine-containing products for at least 24 hours prior to administration of dipyridamole for myocardial perfusion imaging.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.

Do not stop taking any medications without consulting your healthcare provider.
