Are Grapefruits Bad For High Blood Pressure ?

Answer

Hi Idd:

Grapefruit has many nutritional benefits. One concern with grapefruits though is if you are on blood pressure medications there may be food-drug interaction with some medications.

These are some medications with which grapefruit juice should NOT be consumed unless advised by a doctor:

  • Statins (cholesterol-lowering drugs): lovastatin (Mevacor), atorvastatin (Lipitor), simvastatin (Zocor, Vytorin)
  • Antihistamines: Ebastine
  • Calcium channel blockers (blood pressure drugs): felodipine (Nitrendipine, Plendil), nifedipine (Adalat, Procardia)
  • Psychiatric drugs: buspirone (Buspar), triazolam (Halcion), carbamazepine (Tegretol), diazepam (Valium), midazolam (Versed), sertraline (Zoloft)
  • Immune suppressants: cyclosporine (Neoral), (tacrolimus) Prograf
  • Pain medications: Methadone
  • Impotence drug (erectile dysfunction): sildenafil (Viagra)
  • Ant-HIV medication: saquinavir (Invirase)
  • Antiarrhythmics: amiodarone (Cordarone)

Alternatives exist for many of these drugs. If abandoning grapefruit juice is not an option, discuss the possibility of using an alternative with your doctor. And when you are starting a new medication, it is always a good idea to ask your doctor or pharmacist about any potential interactions between the new medication and foods, supplements, or other drugs you are already taking.

Take care,
