Drinking alcohol while taking the pill is also useful, but the rate of contraception will be reduced, which is related to the time of drinking and the amount of alcohol consumed. When taking the pill, try to take it two hours before and after fasting, not only to reduce gastrointestinal reactions, but also to improve the effectiveness of contraception. Although the contraceptive rate of the drug is very high, it is not 100% effective. Alcohol can cause abnormal reactions to the pill, and heavy drinking can seriously affect the effectiveness of the pill and lead to contraceptive failure. The pill is a hormone that interferes with the body’s hormones to change the cervical viscosity, making it difficult for sperm to enter the uterus and inhibiting ovulation, thus achieving the contraceptive effect. Regular use of the emergency contraceptive pill is likely to cause menstrual disorders, and it is not recommended to use this method of contraception.
