Ehkäisylaastarit

Ehkäisylaastarit, also known as contraceptive patches, are a form of hormonal birth control. They are thin, beige, square-shaped patches that are applied to the skin. The patch releases hormones, estrogen and progestin, which are absorbed through the skin into the bloodstream. These hormones work to prevent pregnancy in several ways, primarily by stopping ovulation (the release of an egg from the ovary), thickening cervical mucus to prevent sperm from reaching the egg, and thinning the uterine lining to make implantation less likely.

To use an ehkäisylaastari, a new patch is applied to clean, dry skin once a week for three consecutive weeks. Common application sites include the buttocks, abdomen, upper outer arm, or upper torso (but not the breasts). After three weeks of continuous use, a patch-free week is observed, during which a menstrual period typically occurs. A new patch is then applied on the first day of the following week, restarting the cycle.

The patch is designed to be waterproof, allowing for normal activities like showering, swimming, and exercise. It is important to apply the patch to a different spot each week to avoid skin irritation. If a patch becomes loose or falls off, specific instructions in the product leaflet should be followed regarding reapplication or changing the patch.

Ehkäisylaastarit are a highly effective method of birth control when used correctly. However, like all hormonal contraceptives, they do not protect against sexually transmitted infections. Potential side effects can include skin irritation at the application site, breast tenderness, nausea, and headaches, though many users experience no significant side effects. It is advisable to consult a healthcare professional to determine if the contraceptive patch is a suitable option.
