hätäehkäisyssä

Hätäehkäisy, also known as emergency contraception or the morning-after pill, refers to contraceptive methods used to prevent pregnancy after unprotected sexual intercourse or contraceptive failure. It is not an abortion method and does not terminate an existing pregnancy. Hätäehkäisy is most effective when used as soon as possible after the unprotected event.

There are two main types of hätäehkäisy available. The first is hormonal emergency contraception, typically containing levonorgestrel or ulipristal acetate. These pills work by preventing or delaying ovulation, or by affecting sperm and egg transport. They are most effective within the first 72 to 120 hours after intercourse, depending on the specific medication. The second method involves the insertion of a copper intrauterine device (IUD) within five days of unprotected intercourse. The copper IUD is highly effective and can also serve as a long-term contraceptive method.

Hätäehkäisy is available over-the-counter in many countries, while in others it may require a prescription. It is important to note that hätäehkäisy does not protect against sexually transmitted infections. Regular and reliable contraception methods are recommended for ongoing pregnancy prevention. Side effects of hormonal hätäehkäisy can include nausea, vomiting, headache, and menstrual cycle changes. The copper IUD may cause heavier or longer periods. Consulting a healthcare professional can help individuals understand their options and choose the most suitable method for their needs.
