I forgot my pill
Oral contraception or "pill"
It is with the discovery of the sex hormones and the better knowledge of the ovarian cycle that the idea of using synthetic hormones to obtain a contraceptive effect in women is born. The first tests are conducted in Puerto Rico in 1954 and the first pill is available in 1960 in the United States. In France, it is necessary to wait for the law Neuwirth (1967) so that the pill is distributed.
How it works ?
Most oral contraceptives contain either synthetic estrogen (ethinyl estradiol) or natural estrogen (estradiol) and synthetic progestin of varying nature: these hormones block the production of FSH and LH by the brain and, therefore, the ovulation. They also reduce sperm motility (by thickening the secretions of the cervix) and keep the uterus in a state where the egg is unable to settle. In addition, like the hormones produced by the ovaries, they cause a thickening of the endometrium. During the free period between two platelets (where the woman stops taking hormones), their blood levels drop, which causes the appearance of the rules, as at the end of a normal cycle. This so-called estroprogestative method is extremely reliable provided it is used properly. It is the most common form of hormonal contraception available to women who do not have a particular risk factor. Estrogen / progestin contraception also has non-contraceptive benefits, such as the prevention of ovarian and endometrial cancers.
Other pills and devices contain only progestins that block sperm motility and alter the lining of the uterus to prevent pregnancy. Progestin-only pills are effective as long as they are taken at the same time every day, including during menstruation. Progestins have fewer contraindications than estrogen progestins, but they can still cause small bleeding. Their use is usually limited to women for whom estrogen / progestin contraception is contraindicated.
Hormonal treatments prescribed for acne in women contain both estrogen and progesterone, such as estrogen / progesterone pills. These drugs have contraceptive properties and women who take them do not need any other method of contraception.
The different kinds of pills
Numerous oral contraceptive specialties are available in France, whether they are estroprogestative or progestative. The choice to use one rather than the other depends on the age of the patient, her medical history or possible health problems, the gynecological and medical assessment, but also her lifestyle. It is possible to change methods at any time and it is not uncommon to test several different pills in order to find the one that best suits you. This change must be done according to certain rules.
The pills are available in different presentations, always in tablets. The estrogen / progestative pills have a break of treatment of seven or four days during which bleeding occurs (rules). Even when the hormones are administered for 21 or 24 days (with a rest period), platelets may still contain 28 pills. In this case, the pills taken during the rest period are placebos. Usually of different color, they contain no hormones. They serve to avoid losing the good habit of taking the pill every day and reduce the risk of forgetting.
