Purinethol (mercaptopurine) and Alcohol / Food Interactions
There is 1 alcohol/food/lifestyle interaction with Purinethol (mercaptopurine):
Moderate Food Interaction
ADJUST DOSING INTERVAL: Limited data suggest that food may decrease the oral bioavailability of 6-mercaptopurine (6-MP). In one study, the pharmacokinetics of 6-MP were studied on two separate occasions in seven patients. A single dose of 6-MP was administered after an overnight fast on one occasion and 15 minutes after a standard breakfast on the other. The authors reported that peak plasma levels of 6-MP were lower and took longer to reach following administration in the fed state. In addition, plasma levels were undetectable (less than 20 ng/mL) in two patients.
MANAGEMENT: Until more information is available regarding the effect of food on 6-MP absorption, it may be advisable to take 6-MP on an empty stomach 1 hour before or 2 hours after a meal.
