I entered
ZOCOR and
NIACIN, this is what it says,
NIACIN may interact with SIMVASTATIN (in Zocor)
Although the cause of this potential interaction is not clearly understood, using niacin and simvastatin at the same time could cause a serious or potentially life-threatening side effect that involves the destruction of muscle tissue and could lead to kidney failure. These drugs should generally not be used together unless your doctor is monitoring you very closely. Promptly report any unexplained muscle pain, tenderness, or weakness to your doctor. Ask your healthcare provider about these drugs and this potential interaction as soon as possible.
This interaction is poorly documented and is considered major in severity.
SIMVASTATIN (in Zocor) may interact with GRAPEFRUIT JUICE
Grapefruit juice may block the breakdown of simvastatin in the intestines and thus more simvastatin may get absorbed into the bloodstream. Increased blood levels of simvastatin could cause a serious or potentially life-threatening side effect that involves the destruction of muscle tissue and could lead to kidney failure. Avoid taking simvastatin with any form of grapefruit, including the actual fruit as well as drinks and nutritional supplements that contain grapefruit juice. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
Since I am taking Vitorin, Norsacs and Evista at the same time, this website has been inevaluable to me. I always check before I take any counter drugs, herbs or vitamins. Many products contain citric acid. I don't know if it contains any grapefruit juice. To be safe, I avoid them too.
