Adenosine / lidocaine / magnesium sulfate and Alcohol/Food Interactions

There are 3 alcohol/food/lifestyle interactions with adenosine / lidocaine / magnesium sulfate which include:


adenosine Caffeine

Moderate Drug Interaction

Ask your doctor before using adenosine together with caffeine. Using these medications together can decrease the effects of adenosine. It is recommended that caffeine including caffeine be avoided for 12 to 24 hours before adenosine 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.

ADJUST DOSING INTERVAL: Caffeine and other xanthine derivatives (e.g., theophylline) are nonspecific, competitive antagonists of adenosine receptors and may interfere with the hemodynamic effects of adenosine. There have been case reports of patients receiving theophylline who required higher than normal dosages of adenosine for the treatment of paroxysmal supraventricular tachycardia. In studies of healthy volunteers, caffeine and theophylline have been shown to reduce the cardiovascular response to adenosine infusions (i.e., heart rate increases, vasodilation, blood pressure changes), and theophylline has also been shown to attenuate adenosine-induced respiratory effects and chest pain/discomfort.

MANAGEMENT: Clinicians should be aware that adenosine may be less effective in the presence of xanthine derivatives including caffeine. Patients should avoid consumption of caffeine-containing products for at least 12 hours, preferably 24 hours, prior to administration of adenosine for myocardial perfusion imaging.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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 interaction information available.
