Research has shown that many prescription drugs interact adversely with grapefruit products. Compounds in the fruit known as furanocoumarins may irreversibly inhibit cytochrome P450 3A4 isoenzymes (3A4) in the liver and intestinal wall. This enzyme inhibition decreases pre-systemic metabolism of some drugs taken up to 72 hours after taking grapefruit products, and it could adversely increase their levels within the blood. This resulting increase in drug levels might lead to serious adverse effects and/or toxicity in the body. It is recommended that you consult a healthcare practitioner before taking grapefruit products.
