Please do not drinkl grapefruit juice at the same time as taking prescription meds..... I don't drink grapefruit juice myself, but my dad is on oral diabetes meds and was told to NEVER drink this while on them. Talk to your doctor about any effects that you are having. I haven't personally but some medications should not be taken with grapefruit juice because the juice has certain chemicals in it that block digestion and metabolism of certain types of drugs and can intensify the effect of them.

I have seen prescription bottles that have a sticker on the side that clearly says "Do not take within 2 hours of ingesting grapefruit juice" and then there is a small icon of a halved grapefruit next to it.

I found a source that supports this information.

"Nariginin, a bioflavenoid in grapefruit juice is suspected to be influencing drug metabolism".

Various classes of prescription medications should not be taken at the same time with grapefruit juice. Such classes include some sedatives, antianxiety agents, calcium channel blockers, certain statins (for high cholesterol), and antidepressants. For some reason grapefruit juice can cause unwanted side effects in medications., For instance there is a sleeping pill that you can't take it with.
