Types and usage of oral contraceptives

Oral contraceptives fall into three categories: short-acting, long-acting and quick-acting.

Short-acting oral contraceptives: the mechanism of action is to inhibit ovulation. There are oral contraceptives 1, oral contraceptives 2, and compound contraceptives 18.

Dosage: Take the medicine from the fifth day of menstrual cramps for 22 days. Contraception can be used 1 month. Generally stop taking 1-3 days for menstruation, and continue taking it from the fifth day of the next menstruation. The method is as above.

Why can't you miss taking medicine from the fifth day of menstruation? Because the main function of birth control pills is to inhibit ovulation, if you take the pills after the sixth day and the egg cells develop to a certain extent, the source can't be suppressed, thus causing the possibility of pregnancy, such as leaking drugs halfway, prone to vaginal bleeding and disrupting the normal menstrual cycle.

Long-acting oral contraceptive: Its mechanism is to inhibit and change the running speed of pregnant eggs. Take one contraceptive pill per month 1 month, which is suitable for couples who live together for a long time.

Usage: Take one tablet on the fifth day of menstrual cramps, two tablets on the 25th day, and one tablet on the second day of taking medicine every month.

Quick-acting oral contraceptive: also known as visiting relatives contraceptive. Its mechanism of action is mainly to quickly inhibit ovulation, affect sperm penetration and prevent pregnant eggs from implanting. The advantage is that it is not limited by menstrual cycle, when to visit relatives and when to take it.

Who should not take birth control pills?

Oral contraceptives are simple, but women in the following situations should not take them.

When babies eat this milk, their physical development will be affected, and even some abnormalities will appear, such as breast enlargement, nausea and vomiting, vaginal bleeding of baby girls and testicular atrophy of baby boys.

Second, menopausal women: Due to the endocrine disorder and irregular ovulation of menopausal women, oral contraceptives not only fail to achieve the expected results, but also have an impact on health, which is easy to cause coronary heart disease and gallstones, or uterine bleeding.

Third, women suffering from acute hepatitis, nephritis, heart disease, hypertension, diabetes, hyperthyroidism, uterine fibroids, tuberculosis and other diseases should not take it, so as not to aggravate the condition.

Fourth, women who have had induced abortion should not take it before menstruation, but only after menstruation, so as not to cause uterine atrophy, irregular menstruation or amenorrhea.
