PHILADELPHIA, Aug. 20 (UPI) -- A Canadian researcher warns grapefruit and other juices may cause drugs to be under-absorbed.
Dr. David Bailey of the University of Western Ontario in London, who 20 years ago discovered the "grapefruit juice effect" that an increased absorption of a drug that can result in a toxic overdose, has now found grapefruit as well as apple and orange juices can result in the opposite affect -- a decreased absorption of a drug.
