grapefruit juice contains enzymes that can interact with certain medications like simvastatin by slowing down your body’s ability to metabolize them. this means it will take longer for your body to get rid of the simvastatin when you drink grapefruit juice which can potentially lead to having too much simvastatin in your body. this can lead to more side effects like muscle pains. this interaction does not happen with all the statins. for instance there is no interaction between grapefruit juice and pravastatin found in pravachol.
why should i not drink grapefruit juice while taking simvastatin or other statin drugs?
