Grapefruit Interaction with Medication
Unfortunately grapefruit and grapefruit juice can have unwanted interactions with a range of medications. Researchers have identified 85 drugs which grapefruit is known to have an adverse reaction with. The fruit contains a number of polyphenolic compounds that inhibit drug-metabolizing enzymes in the small intestine, which can lead to increased levels of drug concentration in the bloodstream. Prescriptions medications take into account the rate at which the body breaks down the drug in their dosage recommendations. Because compounds in grapefruit greatly decrease the rate of breakdown, repeated doses can lead to much higher doses of the drug in the bloodstream, potentially leading to harmful side effects.
