Taboos for eating grapefruit When taking some medicine, it will be dangerous to eat with grapefruit. Drinking grapefruit juice while taking medicine = taking poison?

Pharmacokinetics of felodipine was compared with 250 ml grapefruit juice, Guangxi honey grapefruit juice and Changshan grapefruit juice. The results showed that when grapefruit juice and these drugs were taken at the same time, there would be obvious interaction, which led to the increase of blood drug concentration, but Guanximiyou juice and Changshan Huyou juice had no obvious effect.

There are also studies on the interaction between Wendan and cyclosporine (an anti-organ transplant rejection drug) abroad. It was found that the blood concentration of cyclosporine increased slightly after eating 250 grams of Wendan pulp, but the degree of interaction was not as strong as grapefruit juice.

Only some drugs with grapefruit will cause adverse reactions, others, such as Huyou and Wendan, belong to grapefruit, and generally have no obvious effect. In addition, the degree of adverse drug reactions is closely related to the consumption of grapefruit, and large consumption leads to large adverse reactions.

Taking grapefruit contraceptives will fail. Grapefruit has the most prominent influence on contraceptives. Experts say that 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 before, then she may become a mother, because grapefruit hinders women's absorption of birth control pills.

Zhou Quan said that this statement is wrong. In fact, the result is just the opposite. "Contraceptives are mainly hormonal drugs, and drugs need to be metabolized by the metabolic enzyme CYP3A4. If eaten with grapefruit or grapefruit juice, the furocoumarin in grapefruit will inhibit the production of CYP3A4 in human body, and the blood concentration of human body will increase. In theory, the curative effect and side effects will also be enhanced. "

50%-60% of drugs that can't be taken with grapefruit need CYP3A4 metabolism. When taking these drugs, you should avoid eating grapefruit at the same time.
