Warning about risks of grapefruit and medication

by Bruce Gietzen

Health officials are citing a Canadian study that warns people about eating grapefruit while they are taking medications.

Grapefruits contain chemicals called furanocoumarins - that make grapefruit taste bitter - that interfere with how your body breaks down drugs before they enter the bloodstream.  That can effectively cause a drug overdose and severe side-effects.

"Just in the past five years, the number of medications affected by grapefruit has more than quadrupled, from just 17 drugs to 85 different medications," according to Dr. Richard Besser, ABC News' Chief Medical Editor.

It's some of the more popular prescription drugs that can create problems, like statins that lower your cholesterol, other heart drugs, common sleeping pills, anti-biotics and even anti-cancer drugs.

As little as one glass of grapefruit juice or one grapefruit can have an effect that can last up to 24 hours.

They might include sudden death from heart rhythm problems, kidney failure, breathing problems or blood clots.

Health experts suggest every time you're prescribed a new drug, ask if there are any side effects with specific foods.

Here is a list of the medicines you're not recommended to take after eating grapefruit:
