Grapefruit juice contains a substance that slows down your body’s ability to metabolize the Xanax and get it out of your system. So you could have a more pronounced or prolonged reaction from the Xanax.
It is best to avoid grapefruit products when taking a medication like Xanax, so you do not get enhanced side effects.
