Postcoital contraception
Postcoital contraception, also known as emergency contraception, is a type of birth control that can be used by women after an unprotected sexual intercourse. It is used to prevent pregnancy.
Types[edit | edit source]
There are two main types of postcoital contraception: emergency contraceptive pills (ECPs) and intrauterine devices (IUDs).
Emergency contraceptive pills[edit | edit source]
Emergency contraceptive pills are medications taken orally after unprotected sex. There are two types of ECPs: progestin-only and combined oral contraceptives.
Progestin-only ECPs[edit | edit source]
Progestin-only ECPs, such as Plan B One-Step, are the most effective type of ECP. They can be taken up to 72 hours after unprotected sex.
Combined oral contraceptives[edit | edit source]
Combined oral contraceptives, also known as the Yuzpe regimen, consist of both estrogen and progestin. They are less effective than progestin-only ECPs and have more side effects.
Intrauterine devices[edit | edit source]
Intrauterine devices, such as the copper IUD, can be inserted up to five days after unprotected sex. They are the most effective form of postcoital contraception.
Effectiveness[edit | edit source]
The effectiveness of postcoital contraception depends on the type of contraception used and the time between unprotected sex and taking the contraception. In general, the sooner the contraception is taken or inserted, the more effective it is.
Side effects[edit | edit source]
Side effects of postcoital contraception can include nausea, vomiting, abdominal pain, fatigue, dizziness, and changes in menstruation.
