Emergency contraception

To do emergency contraception, you need to pay attention to the following points:

First, there must be a sense of time. Existing research data show that the earlier the effect is, the better the effect is. Do not delay the time. The contraceptives should not exceed 72 hours, especially in the same room during the ovulation period.

Second, emergency contraception is a temporary remedy, and it must be taken within the prescribed period according to instructions. It cannot replace conventional contraceptive methods. The reasons are:

1. Emergency contraception is not as effective as conventional contraception, the former effect makes 80% -85% women and women avoid pregnancy;

2. The emergency contraceptive levonorgestrel (Yuting) is 10 times larger than the conventional oral contraceptive. If it is repeatedly used after each intercourse, it will have an impact on health in the long run; it may even lead to infertility.

3. The emergency contraceptives have certain changes in the menstrual cycle, which may be early or delayed. Repeated taking of emergency contraceptives multiple times will lead to menstrual disorders, bleeding or drip bleeding, which will cause inconvenience to women's life and work. Bring great harm to women's bodies.

3. Emergency contraception has no effect on the prevention of sexually transmitted diseases and AIDS.

First, you must go to a regular pharmacy to buy such drugs. You must not blindly buy such drugs from some private clinics or health food stores. After all, the establishment of regular pharmacies is subject to stricter legal regulations, and their purchases and operations are subject to supervision by the drug regulatory department. It is worth noting that in recent years, so-called spouse health care stores throughout the country, most of which have family planning drugs and medicines for sale, but from the current market status and regulatory norms, its standardization is not as good as regular drug stores.

Secondly, pay attention to identifying some basic drug marks when purchasing drugs. If it is an over-the-counter drug, it should have the word "OTC". If it is marketed after being approved by the State Food and Drug Administration, it must have the "Chinese Medicine Standard" and its serial number, manufacturer, etc. If there is no such information or vagueness, it should be paid attention to, and it can be solved through related queries through the website of the Drug Administration.

In addition, due to the large variety of emergency contraceptives in the market, it is important to distinguish between authentic and fake. Don't just identify the brand and the low price. Nowadays, there are more and more counterfeit products. When choosing, you must pay attention to it.
