Eating grapefruit can be dangerous for people taking certain prescription medications, but many doctors are unaware of the risks.
In a study published in the Canadian Medical Association Journal, researchers said there are now 85 drugs that may interact with grapefruit - and 43 can have serious side effects - or could even cause sudden death.
Researchers say grapefruit poses risks to those taking commonly prescribed drugs such as Lipitor, Zocor, Plavix and oxycodone.
Unless health care professionals are aware of the possibility that the adverse event they are seeing might have an origin in the recent addition of grapefruit to the patient's diet, it is very unlikely that they will investigate it, wrote the authors. In addition, the patient may not volunteer this information. Thus, we contend that there remains a lack of knowledge about this interaction in the general healthcare community.
