There are many types of long-acting birth control pills. The main feature of long-acting pills is that they do not need to be taken every day, but only once to provide a longer-term contraceptive effect. There are many long-acting contraceptive pills, including meprobamate, chlordiazepoxide and others. The method of taking these drugs is basically similar, taking one pill on the 5th day of menstruation, and one pill from the 1st day of menstruation until the 25th day of menstruation, only two pills are needed, and one pill can be taken every month or so later to achieve long-term contraception. However, long-term use of the pill can easily lead to adverse reactions, which can easily exacerbate endocrine disorders and even lead to infertility in serious cases.
