The Morning After Pill Information

Overview

Even the most careful couple can have an accident during intercourse. The Morning After Pill provides an option for preventing an unwanted pregnancy. When other birth control methods have failed, emergency contraception is available as a back up.

Composition

The Morning After Pill is made up of the same hormones as other birth control pills. Some forms of emergency contraception contain one hormone and others contain two. One type contains both progestin and estrogen. The other contains only levonorgestrel.

How To Get It

Any woman over the age of 17 can purchase the Morning After Pill at pharmacies that carry it. You will have to show proof of age. Females under the age of 17 will need a prescription from a doctor.

Function

According to Mayo Clinic, progestin prevents an egg from being fertilized by the sperm. It also keeps the egg from ever implanting into the uterine wall. Estrogen limits the ovaries' ability to release eggs for fertilization. These functions make pregnancy after unprotected sex difficult.

Side Effects

Like most oral contraceptives, the Morning After Pill can cause minor side effects. It is not uncommon to experience headache, nausea, vomiting, menstrual changes, abdominal pain and dizziness. If you notice any other side effects or experience bleeding, contact your medical professional immediately.

Efficacy

According to the manufacturers, the Morning After Pill is effective at pregnancy prevention at a rate greater than 80 percent. Within 72 hours of intercourse you must take the first dose of the pill. The next dose is to be taken 12 hours later.
