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. Show
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.

I like to drink grapefruit juice but hear that it can interfere with some prescription medications. Is that true?Answer From Katherine Zeratsky, R.D., L.D. Yes. Grapefruit and certain other citrus fruits, such as Seville oranges, can interfere with several kinds of prescription medications. Don't take these interactions lightly. Some can cause potentially dangerous health problems. If you take prescription medication, ask your doctor or pharmacist whether your medication interacts with grapefruit or other citrus products. You may need to eliminate grapefruit products from your diet. Simply taking your medication and grapefruit product at different times doesn't stop the interaction. Alternatively, you can ask your doctor if there's a comparable medication you can take that doesn't interact with grapefruit. Problems arise because chemicals in the fruit can interfere with the enzymes that break down (metabolize) the medication in your digestive system. As a result, the medication may stay in your body for too short or too long a time. A medication that's broken down too quickly won't have time to work. On the other hand, a medication that stays in the body too long may build up to potentially dangerous levels. The list of medications that can interact with grapefruit includes commonly prescribed medications that:
Another potential problem is that some foods and drinks may contain grapefruit but don't say so in the name or on the ingredients list. For example, numerous citrus-flavored soft drinks contain grapefruit juice or grapefruit extract. Play it safe with prescription drugs. Always ask your doctor or pharmacist when you get a new prescription if it interacts with any foods or other medicines. If the answer is yes, ask whether you need to eliminate that food from your diet.
