I looked into this quite a bit a while back. There was a guy who drank 2 gallons of grapefruit juice and had a bad interaction. In my opinion it is being a little too cautious to ban ban grapefruit and taking statins. When the grapefruit start to get good in my backyard, I drink the occasional glass. When I get a slug of fruit, I stop taking the statin for a month. Apparently the impact of the statins hangs around a while after they are stopped. I'm taking the statin as my cholesterol was 200, the old maximum. Some time ago the max was reduced again such that almost no one can meet it without taking statins. Hmm, you suppose the drug companies had anything to do with that? Phi on them, my statin is a generic costing $8 a month from Walmart.
