No interaction. Not sure if this is what you meant to ask. But there is no known interaction between the two medicines. Also, the half-life (time it takes for half to disappear) of Adenosine is less than 10 seconds and thus not likely to cause much problem even if it does. Adenosine is usually given via IV push hoping to correct a specific heart arrythmia n it is gone in seconds/minutes. Ask again if u need to..
