Health issues with grapefruit?

My sister has received a half case of grapefruit. She was told by her doctor to avoid grapefruit due to drug interactions. She was wondering if she could use the juice for a marinade that is then cooked. Also could she eat candied grapefruit rind? TIA.

  1. My understanding is that any sort of grapefruit can cause an adverse interaction in certain drugs. She should ask her pharmacist or doctor, though.

    1. a web search turns up this information, but checking with your physician is the best advice when it comes to health matters:

      1. She should definitely avoid grapefruit if she is on a statin drug such as Lipitor or Zocor.

          My father has been on Lipitor for many years. His doctor told him he could have a grapefruit 10 -12 hours before/after taking his Lipitor. Since he prefers having the grapefruit with his evening meal, he takes Lipitor in the morning. I am quite sure there are many people on Lipitor who should avoid eating grapefruit.

          I understand that grapefruit can interfere with other kinds of medication as well.

            Or avoid the statins and eat the grapefruit.

              It's not just statins... grapefruits have a unique chemical composition that affects a LOT of medications including anti-depressants and various other psychotropic medications. She'd be best off to get rid of the grapefruit and not take a risk.

            2. Until cleared with her dr for the specific meds she is on she needs to avoid the grapefruit raw/cooked/juiced etc and follow his advice for her specfic regimin.

              1. I too read about this some time ago and have avoided grapefruit since I'm on meds.

                But what about other citrus fruits?

                I'm thinking about pomelos and tangelos which may be/are related by hybridisation.

                  Since both grapefruit and tangelos are hybrids of pommelos, I would ask the doctor who prescribed the medications before consuming either variety of citrus.

                    Aye, that's my intention on my next visit. Avoidance till then.

                    I'm more concerned about folks who may not be aware.

                      What is mildly interesting about my father's situation is that he has a ruby red grapefruit tree at his winter home in Arizona. (He also has two orange and two lemon trees.)
