Why should I avoid eating grapefruit if I am on blood pressure medication?

answer

A beta blocker with a grapefruit juice chaser may nix the effectiveness of the blood pressure medication, thanks to the chemical behind the fruit's tart taste. Another chemical in that fruit may actually boost the effects of other blood pressure drugs. Either way, you're not getting what you need, so keep grapefruit and blood pressure meds away from each other.

If you're on blood pressure medication, you should avoid eating grapefruit. The reason why is that grapefruit is very acidic and breaks down certain medications much faster. For some people, this causes them to absorb too much of the medicine and for others, not enough. Blood pressure medications that are affected by grapefruit juice include calcium channel blockers such as nifedipine.
