As stated in the article, “Grapefruit’s culprit chemical does not interact directly with your pills. Instead, it binds to an enzyme in your intestinal tract known as CYP3A4, which reduces the absorption of certain medications.

Blood levels will rise faster and higher than normal, and in some cases the abnormally high levels can be dangerous.
