Levonorgestrel (Levonorgestret)

Levonorgestrel is a synthetic female sex hormone belonging to the class of progestogens. It is widely used in various forms of contraception, both in combination with estrogen in oral contraceptives and in progestogen-only preparations.

Levonorgestrel is one of the most effective and popular contraceptive options. It has the ability to prevent or delay ovulation, that is, the release of an egg from the ovary. In addition, it changes the lining of the cervix, making it less permeable to sperm, and affects the preparation of the endometrium (the inner layer of the uterus), which makes it difficult for a fertilized egg to attach.

Levonorgestrel is not only used as a method of contraception, but can also be used for other medical purposes. For example, it can be used as emergency contraception (sometimes called "morning after"). In the event of unexpected sexual intercourse or failure of a regular method of contraception, levonorgestrel may be taken within 72 hours (or in some cases up to 120 hours) after sexual intercourse to prevent pregnancy.

In addition, levonorgestrel may be used to treat certain gynecological conditions, such as menorrhagia (heavy and prolonged monthly bleeding) or endometriosis (a condition in which the endometrium, which normally lines the inside of the uterus, begins to grow in other areas).

Like any medical drug, levonorgestrel has its contraindications and side effects. Some of these include nausea, headache, changes in the menstrual cycle and breast tenderness. It is important to check with your doctor or pharmacist before starting to use levonorgestrel or any other method of contraception to be informed about the risks and benefits, especially if you have any medical problems or contraindications.

Overall, levonorgestrel is an effective and widely used method of contraception. It offers women a variety of choices and control over their reproductive health. However, before use, you should consult with a medical professional to determine the most appropriate contraceptive option based on your individual characteristics and needs.

Levonorgestrel: synthetic female sex hormone, progestogen

Levonorgestrel is a synthetic female sex hormone, progestogen, which is widely used in the field of contraception. It is used primarily in oral contraceptives, both in combination with estrogen and as a progestogen-only drug.

Progestogens play an important role in the female reproductive system, regulating the menstrual cycle and maintaining pregnancy. Levonorgestrel has a strong contraceptive effect, preventing ovulation (the release of an egg from the ovary) and changing the lining of the uterus, which makes it difficult for the fertilization process and implantation of the fertilized egg.

One of the most common ways to use levonorgestrel is in oral contraceptives, which contain a combination of levonorgestrel and estrogen. These medications offer a reliable and convenient form of contraception, preventing pregnancy when taken correctly and regularly.

In addition, levonorgestrel can be used as a progestogen-only method of contraception. It can be used in the form of special preparations, such as a medicated coil or subcutaneous implants. These methods provide long-term protection against pregnancy, and their effectiveness can last from several months to several years, depending on the specific drug.

Levonorgestrel can also be used as emergency contraception, known as the "morning after" or "morning after" pill. In cases of unprotected intercourse or failure of conventional contraceptive methods, taking levonorgestrel within a certain time window after intercourse may help prevent pregnancy.

It is important to note that levonorgestrel does not prevent the transmission of sexually transmitted infections, and its use should be combined with the use of condoms or other methods of protection if there is a risk of infection.

Overall, levonorgestrel is an important tool in modern contraception, offering women a variety of methods of choice depending on their needs and preferences. However, before starting to use any method of contraception, it is recommended to consult a doctor to choose the most appropriate and safe option, taking into account the individual characteristics and medical history of the patient.
