Grapefruit Juice Not Good for Prescription Medications

Grapefruit juice is not good for people taking certain prescription medication. The juice has natural enzymes that can block the body's ability to break down certain drugs and this can cause the drug's levels to increase to high levels and increase the risk of side effects. Just one glass of juice can be enough to cause problems. It is good to check the prescription label for grapefruit caution.
