The hazards of birth control pills: What are the reasons for the failure of oral contraceptives
Oral contraception is a common method of contraception. The method of oral contraception has a high rate of safety and contraception, but oral contraception has a curse, and the harmful effects of contraception are significantly reduced or ineffective. Recently, it has been found that many drugs can interfere with the effect of oral contraceptives, such as phenytoin sodium, Phenobarbital, phenazone, and Rimantine, which can affect the contraceptive effect of women taking contraceptives.
Oral contraceptive pills are simple and easy to use for contraception. According to reports, 560 million people worldwide use this method of contraception. However, it is not well known that women who take birth control pills may fail if they take special medications. Stability is one of them.
This drug is an inducer of liver microsomal enzymes and can accelerate the metabolism of oral contraceptives in the body, thereby reducing their contraceptive effect. Long term use of stable sleep aids undoubtedly interferes with the effectiveness of birth control pills. In addition to stability, in recent years, it has been found that there are many drugs that can interfere with oral contraceptives, such as phenytoin sodium, Phenobarbital, phenazone, and Rimantine, which can affect the contraceptive effect of women taking contraceptives.
In addition, the long-term use of penicillin, Erythromycin and Chloramphenicol and the equal interests of anti tuberculosis drugs may also affect the contraceptive effect. The reason is that under normal circumstances, the oral contraceptives release a Hydrolase with the help of intestinal bacteria, which is repeatedly absorbed in the hepatointestinal circulation. If this hepatic intestinal circulation is blocked, contraception may fail. The above antibacterial drugs have this effect.
Therefore, if women of childbearing age need to take oral contraceptives for a long time during their illness, they should explain their use of contraceptives to doctors for their reference. It is safer to stop taking oral contraceptives and switch to other effective contraceptive methods.
