Study: Dozens of drugs should not be taken with grapefruit juice

Before you pour a glass of grapefruit juice with breakfast , check your medicine cabinet.

A new study issued Monday in the Canadian Medical Association Journal says 43 prescription drugs can cause serious side effects if taken with grapefruit juice.

That's up from a list of 17 just four years ago.

"Certain chemicals that grapefruit products and citrus fruits contain can interfere with the enzymes that break down (metabolize) various medications in your digestive system," a post on the Mayo Clinic website by Katherine Zeratsky R.D. reads. "As a result, more medication stays in your body. This can increase the potency of your medication to potentially dangerous levels, causing serious side effects."

The side effects vary depending on the drug but can include a bleeding stomach, altered heart beat, kidney damage and in some cases, death.

Check with your pharmacist before mixing any prescription drugs and grapefruit juice.
