When taking one of these medications and drinking grapefruit juice, the grapefruit inhibits the metabolism of these drugs (i.e. it is hogging the enzyme all to itself in the liver and not leaving any for the medication so it can't be broken down). The result is having too much of the medication in your body, which can lead to toxicity. Answer:Grapefruit, and grapefruit juice contains several antioxidants that block the enzyme CYP3A4 for roughly 24 hours. This enzyme is responsible for breaking down certain types of drugs. when you take a drug while this enzyme is blocked it might increases the effects of the drugs. Depending on the drug, it can cause reactions that are either minimal, serious, or non existant.

Katherine Zeratsky, a Mayo Clinic Nutritionist, explains, "Problems arise because chemicals in the fruit can interfere with the enzymes that break down (metabolize) the medication in your digestive system. As a result, the medication may stay in your body for too short or too long a time. A medication that's broken down too quickly won't have time to work. On the other hand, a medication that stays in the body too long can increase to potentially dangerous levels, causing serious side effects."
