Thanks Jackie. Good articles.
I don't know about grapefruit and ER/PR, but I do know that grapefruit interacts negatively with some medications. Be sure to ask for literature every time you get a new medication. You can also check for drug to food interactions, drug to drug interactions or drug to supplement interactions on
www.drugs.com or other reliable sites devoted to that kind of activity.
I do that every time I get a new prescription from a medical professional.
