How Grapefruit Juice Can Interfere With Medications

With most drugs that are affected by grapefruit juice, the juice lets more of the drug enter the blood, says Shiew Mei Huang, Ph.D., of the FDA. When there is too much drug in the blood, you may have more side effects.

For example, if you drink a lot of grapefruit juice while taking certain statin drugs to lower cholesterol, too much of the drug may stay in your body, increasing your risk for liver and muscle damage that can lead to kidney failure.

Many drugs are broken down with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of intestinal CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body.

The amount of the CYP3A4 enzyme in the intestine varies from person to person. Some people have a lot of this enzyme and others just a little. So grapefruit juice may affect people differently even when they take the same drug.

Although scientists have known for several decades that grapefruit juice can cause too much of certain drugs in the body, more recent studies have found that the juice has the opposite effect on a few other drugs.

Why this opposite effect? Instead of changing metabolism, grapefruit juice can affect proteins in the body known as drug transporters, some of which help move a drug into our cells for absorption. As a result, less of the drug enters the blood and the drug may not work as well, Huang says.

Grapefruit May Help Control Blood Sugar

Grapefruit also has a low glycemic index , around 25, which means it doesn’t raise blood sugar as quickly or as much as high-GI foods like white bagel or even a banana or watermelon .

A 2006 study published in the Journal of Medicinal Food, found that people who ate grapefruit before a meal had a lower spike in insulin two hours later than those taking a placebo, and fresh grapefruit was associated with less insulin resistance. All 91 patients in the 12-week study were obese, but they did not necessarily have type 2 diabetes.

While the results are promising in those without diabetes, blood-sugar reactions to food can vary widely, so if you have been diagnosed with type 2 diabetes, test your blood sugar after eating grapefruit to make sure it can be part of your healthy eating plan.

Grapefruit Juice And Medication

As healthy as grapefruit juice is, it can become a health hazard when combined with certain medications. Grapefruit juice, and sometimes grapefruits, can negatively interact with medications used for high blood pressure, high cholesterol and depression, such as some calcium channel blockers, statins, immunosuppressants, benzodiazepines, beta blockers and other drugs.

It is said that a compound called furanocoumarin, that can also be found in Seville oranges, is responsible for these effects. In particular, the furanocoumarins bergapten and dihydroxybergamottin have been studied. The mechanism causing this effect is the grapefruit juices ability to inhibit cytochrome P-450 3A4 isoenzyme and P-glycoprotein transporters in the intestine and liver. Inhibiting the cytochrome P-450 3A4 results in slowing down the guts metabolism, consequently increasing the bioavailability of orally administered drugs, by a reduction in the first-pass effect. The P-glycoprotein inhibition also leads to increased levels of the drug in the serum, due to efflux action of P-glycoprotein . Therefore, grapefruit juice boosts the effects of certain medications by increasing bioavailability, which can pose a serious risk to patients taking the drugs. For these patients it is advised to switch from grapefruit juice to orange juice.
