Introduction
Whether contraceptive pills need to be taken on an empty stomach mainly depends on the type of contraceptive used. Short-acting oral contraceptives generally do not need to be taken on an empty stomach. However, emergency contraceptive pills might require administration on an empty stomach. Regardless of whether contraceptive pills are taken on an empty stomach or after a meal, it is important to carefully read the drug instructions and strictly follow the requirements outlined in the instructions to ensure stable hormone levels in the body.

Whether oral contraceptives need to be taken on an empty stomach mainly depends on the type of contraceptive being used. If it is a short-acting oral contraceptive, typically there is no need for an empty stomach. However, if it is an emergency contraceptive, taking it on an empty stomach may be required. Detailed explanation is as follows:

Most short-acting oral contraceptives are designed considering individual differences in absorption, so they can be taken with or after a meal to reduce the possibility of gastric discomfort, and they do not strictly require administration on an empty stomach. For example, common combined oral contraceptives and progestin-only contraceptives are usually recommended to be taken at a fixed time each day to maintain stable drug concentrations, but taking them on an empty stomach is not mandatory.

On an empty stomach, drugs are usually absorbed into the bloodstream more quickly and thus can take effect faster. For emergency contraceptives, taking them on an empty stomach may help increase the absorption rate, thereby potentially improving contraceptive effectiveness to some extent.

Regardless of whether contraceptives are taken on an empty stomach or after a meal, it is important to carefully read the drug instructions and strictly follow the guidelines to ensure stable hormone levels in the body.

What happens if you take emergency contraception 15 days after an abortion?
Fifteen days after an abortion, the body has not yet fully recovered. Taking emergency contraceptive pills at this time may generally lead to menstrual disorders, worsen gastrointestinal discomfort, and interfere with endometrial repair. Emergency contraceptive pills contain high doses of hormones. Since hormone levels in the body are already undergoing adjustment after an abortion, taking these pills can easily disrupt hormonal balance, causing the menstrual cycle to come earlier or be delayed, and in some cases may also result in abnormal menstrual flow.

Why can emergency contraceptive pills only be taken three times a year?
It is recommended that emergency contraceptive pills should not be taken more than three times a year, primarily because frequent use can lead to various health effects, including hormonal imbalance, menstrual disorders, reduced contraceptive effectiveness, increased risk of gynecological diseases, and physical discomfort.
