ehkäisylaastareina

Ehkäisylaastari, known in English as the contraceptive patch, is a transdermal patch used for birth control. It is a thin, beige plastic square, typically measuring about 4.5 cm by 4.5 cm. The patch is applied to the skin and releases hormones—estrogen and progestin—which are absorbed into the bloodstream. These hormones work by preventing ovulation, thickening cervical mucus to impede sperm movement, and thinning the uterine lining.

The patch is designed to be worn for one week at a time. A new patch is applied on the same day each week for three consecutive weeks, followed by a patch-free week during which menstruation occurs. The application site should be rotated to prevent skin irritation. Common application sites include the buttocks, abdomen, upper outer arm, or upper torso.

Ehkäisylaastari is a highly effective method of contraception when used correctly, with a failure rate of less than 1% when used perfectly. It offers convenience as it does not require daily attention, unlike some other contraceptive methods. However, like all hormonal contraceptives, it can have side effects, which may include nausea, breast tenderness, headaches, and mood changes. It is also associated with a slightly increased risk of blood clots, although this risk is still relatively low.

The decision to use ehkäisylaastari should be made in consultation with a healthcare provider, who can assess individual suitability and discuss potential benefits and risks. It is not suitable for everyone, particularly individuals with a history of certain medical conditions.
