Types and uses of oral contraceptives

       What types of oral contraceptives are there? How to use it? Oral contraceptives are broadly divided into three categories:

　　short-acting oral contraceptive pills : The mechanism of action is to inhibit ovulation. There are oral contraceptive tablets No. 1, oral contraceptive tablets No. 2 and compound 18A contraceptive dropping pills.

　　How to take: Start taking the medicine on the 5th day from the day of menstruation, and take it for 22 consecutive days without any interval. It can be used as a contraceptive for 1 month. Generally, menstruation will occur within 1 to 3 days after stopping the drug. Then continue taking it from the 5th day of the next menstruation. The method is the same as above.

　　Why should I start taking medicine on the 5th day of menstruation and not miss a dose? Because the main function of birth control pills is to inhibit ovulation, if the pill is taken after the 6th day, the egg cells will not be able to inhibit ovulation until the egg cells have developed to a certain extent, thus causing the possibility of pregnancy. If the pill is missed in the middle, vaginal bleeding is likely to occur, disrupting the normal menstrual cycle.

　　Long-acting oral contraceptives: Its mechanism of action is to inhibit and change the speed of the pregnant egg. Taking one tablet every month can prevent pregnancy for one month. It is suitable for couples who live together for a long time.

　　How to take: Take one tablet on the 5th day of menstruation, 2 tablets on the 25th day, and then take one tablet on the same day of the second dose every month.

　　Rapid-acting oral contraceptive pills: Also known as the visiting family contraceptive pill. Its mechanism of action is mainly to quickly inhibit ovulation and affect sperm Penetrate and prevent the fertilized egg from implanting. The advantage is that it is not restricted by the menstrual cycle and can be taken when visiting relatives.

　　Birth control pills prevent pregnancy through the action of drugs. Contraceptive pills are divided into male contraceptive pills and female contraceptive pills. Male contraceptives generally inhibit the production of sperm and reduce the number of sperm, resulting in few or even no sperm and inability to conceive.

　　Recently, it has been discovered that many drugs can interfere with the effect of oral contraceptives, such as phenytoin, phenobarbital, chlordiazepoxide, etc., which can affect the contraceptive effect of women taking contraceptive pills. >>>> Promote breast development6food-like
