A daily glass of grapefruit juice can boost the effectiveness of a cancer drug, allowing patients to take a much lower dose. The combination could help patients avoid side effects associated with high doses of the drug and reduce the cost of the medication. In a study published in August in Clinical Cancer Research, researchers at the University of Chicago show that eight ounces a day of grapefruit juice can slow the body’s metabolism of a drug called sirolimus, which has been approved for transplant patients but may also help many people with cancer.
