My grandfather used to eat grapefruit every day, but had to give it up when he was prescribed Warfarin (a blood thinner). Ironically it seems that it would have been just fine for him to continue so long as he stuck to religiously eating grapefruit every day. He would have needed a substantially lower dose of the drug, but Warfarin is one where you adjust the dose a lot for each patient anyway: the manufacturer recommends starting with 6mg and ending up anywhere from 0.5 to 10mg depending on the patient's response [0].
He was also hospitalised several times, both for his heart problems and stomach cancer. I wonder if hospitals keep grapefruit on hand for patients like this, or if they ban it altogether.
