Mafolone is a short-acting contraceptive pill whose main active ingredients are deoxyprogesterone and ethinyl estradiol, and it is a compound preparation. It mainly plays a contraceptive role by inhibiting the normal ovulation function of the ovaries, changing the properties of cervical mucus and preventing sperm penetration. It is mainly used clinically for contraception, but can also be used for artificial cycles to regulate menstruation. When taking Mafron, it is usually taken from day 1-5 of the menstrual cycle, for 21 days and stopped for 7 days. The next menstrual cycle must be taken at exactly the same time as the first one. If a missed dose occurs during the dosing period, it should be promptly replaced within 12 hours. Withdrawal bleeding usually occurs 2-3 days after stopping the medication.
