ehköisylaastari

Ehkäisylaastari, commonly known as the contraceptive patch, is a thin, beige-colored patch worn on the skin that releases hormones to prevent pregnancy. It is a type of combined hormonal contraceptive, containing both estrogen and progestin. The hormones are absorbed through the skin into the bloodstream.

The patch is typically applied once a week for three consecutive weeks, followed by one week without a patch, during which a menstrual period occurs. A new patch is applied on the same day of the week each week. The patch can be worn on the buttocks, abdomen, upper outer arm, or upper torso, avoiding the breasts. It adheres to the skin and is waterproof, meaning it can be worn during showering, swimming, or exercise.

The primary mechanism of action of the ehkäisylaastari is to prevent ovulation, the release of an egg from the ovary. It also thickens cervical mucus, making it more difficult for sperm to reach the egg, and thins the uterine lining, making it less receptive to implantation.

Ehkäisylaastari is a highly effective method of contraception when used correctly. Its effectiveness is comparable to birth control pills. However, like all hormonal contraceptives, it does not protect against sexually transmitted infections. Potential side effects are similar to those of other combined hormonal contraceptives and may include nausea, breast tenderness, headache, and mood changes. It is important to consult a healthcare professional to determine if the ehkäisylaastari is a suitable option for individual needs and health history.
