What are the commonly used COCs? The third generation oral contraceptives in common use today are Mafloquine, Daing-35, and Mintin even. The fourth-generation oral contraceptives include Ursine and Worcester. They have basically the same efficacy, but each has its own characteristics because of the different types of progestin and different estrogen content in COCs. Daing-35, which contains cyproterone, has the strongest effect of reducing androgens. Drospirenone in Ursine and Ursine is closer to the pharmacological properties of natural progesterone, and its androgen-lowering effect is not as strong as that of Daing-35, but it has fewer side effects, does not cause weight gain due to water and sodium retention, and is beneficial to blood pressure and blood lipids. How to take COC correctly? The use of COC varies depending on the purpose of treatment and may differ between drugs. For example: if used to stop bleeding, your doctor may have you take 2-3 tablets a day or more by mouth, and then gradually reduce the dose to 1 tablet a day after 3 days of stopping bleeding, and then stop taking the drug after a period of time; if used to regulate your menstrual cycle, your doctor may have you start using 1 tablet a day on one day of your period until you finish the last tablet of a box of pills (28 tablets in a box of Eusebio, compared to 21 tablets for other birth control pills), and then take it periodically. If you are using it for contraception, you should start taking it on the first day of your period and stop taking it for a week after you finish taking one box of pills and start taking the next box, while you don’t need to stop taking it and take the next box after you finish taking one box of pills. You should follow your doctor’s instructions on how to use it. What should I pay attention to when taking COC? It is important to note that you should not miss a dose of COC, and if you miss a dose, you should take the next dose as soon as you remember and still take the next dose at the regular time. If you take COC for a long time, you should go to the hospital for regular follow-up medical checkups. Women taking COC should not smoke, drink more water, and not be sedentary. Oral COC adverse reactions A small number of women may experience some adverse reactions when using COC, it is related to the type of COC and the tolerance of different women, generally these side effects can be tolerated, some women can not tolerate the type of COC to reduce the side effects.

Vaginal bleeding usually occurs at the early stage of taking the medication and is manifested as spot bleeding or menstrual-like breakthrough bleeding.

Decreased menstrual flow Because COC can inhibit endometrial proliferation, resulting in decreased menstrual flow or menopause.
