口服短效避孕药是由人工合成的雌激素和孕激素等成分组成,服用时要注意食品和某些药物的影响,否则可能影响药效。柚子是很多女性冬季常吃的水果,但服避孕药期间最好不要吃。美国的一项研究显示,服避孕药的女性如果在性生活后立即吃柚子,或者服避孕药前后短时间内喝柚子汁,那么发生意外怀孕的风险会大大增加。这是因为柚子会抑制人体酶的代谢,影响避孕药的吸收和利用。柑橘类水果及果汁也有类似作用,服避孕药期间最好不要大量吃。
Short-acting oral contraceptives are composed of synthetic estrogen and progesterone and other ingredients, taking time to pay attention to the impact of food and certain drugs, or may affect the efficacy. Grapefruit is a lot of women eat fruits in winter, but it is best not to eat during pregnancy contraceptives. A United States study shows that women taking contraceptives if they eat grapefruit immediately after sex, or drink grapefruit juice shortly before and after taking the pill, then the risk of unwanted pregnancies will greatly increase. This is because grapefruit will inhibit the metabolism of human enzymes, affecting the absorption and utilization of contraceptives. Citrus fruits and juices also have a similar effect, it is best not to eat large quantities of contraceptives.
