Emergency contraceptives are usually completely metabolized in about 3-5 days, but the time it takes for different types of emergency contraceptives to be completely metabolized in the body varies somewhat. There are many different types of emergency contraceptives, and different emergency contraceptives contain different amounts of hormones, so the metabolism time varies. Generally, most of the emergency contraceptive pills can be metabolized within 3 days after taking them, but even if the pills are completely metabolized, they can still have long-lasting effects on the body, such as withdrawal bleeding about a week after taking the pills, and endocrine function can be affected to varying degrees within 1 month. Therefore, the interval between emergency contraceptive pills should not be less than 3 months and not more than 3 times a year. In addition, it is recommended that women drink more water after taking the emergency contraceptive pill to promote the excretion of the drug, and pay attention to rest, strengthen diet and nutrition, and eat more vegetables and fruits. If you have any discomfort, go to the gynecology department in time.
