Eat grapefruit in moderation. If you eat too much grapefruit at a time, it will not only affect the detoxification function of the liver, but also cause other adverse reactions, even poisoning, including dizziness, nausea, palpitation, tachycardia, fatigue, hypotension and other symptoms. Eating grapefruit or drinking grapefruit juice during taking the antiallergic drug Terfenadine is particularly dangerous, which can lead to arrhythmia and even sudden death in severe cases.

There are many drugs that can interact with grapefruit, such as calcium antagonists such as nifedipine, verapamil and diltiazem, antipsychotics such as clozapine, gastrointestinal drugs such as cisapride, immunosuppressants such as cyclosporine A and central stimulants such as caffeine.

Experts pointed out that when taking these drugs, just drinking a glass of grapefruit juice may cause the above effects. Therefore, medical experts earnestly warned patients, especially elderly patients, not to eat grapefruit and not to drink grapefruit juice when taking medicine to prevent accidents.

Extended data:

Three kinds of people don't eat grapefruit:

1, women who take birth control pills should avoid eating them.

A study in the United States shows that grapefruit has the most prominent influence on contraceptives. Experts say, "If a woman who takes birth control pills eats 1 ~ 2 grapefruit after sex, or takes birth control pills directly with a large glass of grapefruit juice, then she may become a mother, because grapefruit hinders women's absorption of birth control pills."

2. People with deficiency and cold should not eat more.

Grapefruit is cold, and people who have diarrhea due to spleen deficiency will have diarrhea after eating grapefruit, so people with deficiency cold should not eat more.

3. Patients with hypertension should not eat grapefruit when taking medicine.

Experts suggest that you should not eat grapefruit or drink grapefruit juice during taking antihypertensive drugs, otherwise there may be serious side effects such as sudden drop in blood pressure. Grandma Cai has had high blood pressure for many years. She has been taking medicine on time, paying attention to her diet and controlling her blood pressure well. 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.

Who knows, recently, after eating more than half a grapefruit, Cai's mother-in-law appeared dizziness, nausea, palpitation, fatigue, hypotension and other symptoms. 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.
