When checking interaction based on authoritative sources Drugs.com, Rxlist.com, Webmd.com, Medscape.com there are contraindications or side effects that may cause harm or increase the negative effect from drug interaction with food or lifestyle.

Consumer:

Caffeine may interfere with the effects of dipyridamole in dilating the arteries. You should avoid caffeine-containing products for at least 24 hours before an imaging procedure involving dipyridamole given by injection. However, no special precaution is necessary if you are taking dipyridamole orally for maintenance.

Professional:

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.
