Some patients may have dizziness, palpitation, arrhythmia, etc. if they eat grapefruit or drink grapefruit juice during taking the antiallergic drug Terfenadine, and in severe cases, they may die suddenly. Other drugs that have side effects on grapefruit are cyclosporine, caffeine, calcium antagonists and cisapride. Drinking a glass of grapefruit juice will last for 24 hours. Therefore, patients taking medicine, especially the elderly, had better not eat grapefruit or drink grapefruit juice.

Recently, she heard that grapefruit is rich in vitamin C and a variety of insulin, which can lower blood fat and blood sugar, so she often eats grapefruit.

Liu Peng, a doctor, said that if you take grapefruit at the same time when taking antihypertensive drugs, just like taking too many antihypertensive drugs, it will obviously lower your blood pressure and even induce angina pectoris, myocardial infarction or stroke.
