Patient's question:
How long does the short-term birth control pill Chiyikeiting take to become effective?Doctor's answer:
The main components of oral contraceptives are artificially synthesized combined estrogen and progestogen. They are divided into three types based on the duration of contraceptive effect: long-acting, short-acting, and rapid-effect (visiting). Currently, combined short-acting oral contraceptives are the most commonly used.Combined short-acting oral contraceptives are easy to take, highly effective in contraception, harmless to the body, and do not affect future fertility. Generally, they are taken after dinner before going to bed on the 5th day of menstruation, with one tablet taken daily for 21 consecutive days, followed by a 7-day break. Then, the next cycle of contraception begins.
Rapid-effect (visiting) contraceptives are suitable for couples staying together continuously for more than 10 days. They can be taken after sexual intercourse and are not restricted by the menstrual cycle. If the visit exceeds two weeks, it is recommended to switch to regular contraceptive pills.
Long-acting oral contraceptives: On the 5th day of menstruation, take one tablet after lunch. Wait 20 days to take the second dose, and thereafter, take one tablet monthly on the date of the second dose.
