the problem with grapefruit is, grapefruit interfers with several medications, affecting metabolism and ability to clear drugs from the body:
“Interactions with grapefruit can occur with common and important medications - such as those that lower cholesterol, treat high blood pressure, or even those that fight cancer.
“ Grapefruit juice affects how drugs are changed (metabolized) in the body for eventual elimination and can alter the amount of drug in your blood. This can lead to enhanced side effects or lower drug effectiveness.
“Examples of common medications that interact with grapefruit juice include certain statin cholesterol drugs such as atorvastatin (Lipitor), lovastatin, simvastatin (Zocor), felodipine (Plendil) and other calcium channel blockers, clarithromycin (Biaxin), and loratadine (Claritin). Some immunosuppressants have been reported to cause kidney damage, and certain pain medications when mixed with grapefruit juice may be linked with depressed breathing.”
