Not just grapefruit either (although it's one of the worst things u can have if on Calcium blockers such as Nifedipine). Always make sure u read the info sheet, GP's don't always give u all the info u need :0)


Most citric fruit juices can affect the INR if you are on warfarin, as can painkillers, and antibiotics, to name a few. Bit like a minefield really.



I was warned NOT to have any grapefruit after my renal transplant as this affects Tacrolimus (Prograf). Doctors have a duty to tell you what to avoid when they prescribe new meds.
