I love Eating this one variety of Philippine grapefruit. However, I m presently taking metformin, glipizide, amlodopine, hyzaar, metoprolol, Lipitor. My husband is taking metformin, glipizide, lisinopril, atenolol, Crestor, levothyroxide. Will eating grapefruit affect our medications? Is it okey to eat the grapefruit after 2 hours after we take our mess?
