Thank you very much for reading and for the question. I haven’t been able to do detailed research on that yet. But here are what I have found so far.

The problem with grapefruit and statins is that grapefruits contain compounds called furanocoumarin. This compound inhibits an enzyme in the body that helps clear off drugs (i.e., statins) from your blood circulation, thus resulting in a high amount of statins in the blood circulation. Because your body is exposed to statins for a longer time, the chances of getting side effects from the drugs are more likely.

However, not all statins are affected equally by grapefruit juice. For example, atorvastatin, lovastatin, and simvastatin are more affected by grapefruit juice while other statins like fluvastatin, pitavastatin, pravastatin, and rosuvastatin are less or not affected by grapefruit juice.

Also, according to Harvard’s health blog, a small glass of grapefruit juice (less than a quart) or eating half a grapefruit should be fine. But just to be safe, it’s best to avoid taking the pills with grapefruit juice and consult the doctor if experiencing any discomfort.

This is it for now. I hope you find it helpful. Nevertheless, I will do thorough research on this topic and see what I can find. Perhaps I will cover it in my next or future article. :)
