What’s the Difference between the Morning-After Pill and Abortion Pill?

Many people think that they are the same but these two pills actually play completely different roles. A morning-after pill is a medication used for emergency contraception and does not induce an , whereas an abortion pill is used to terminate an unwanted early pregnancy (we generally do not recommend the abortion pill as the duration of bleeding and severity cramping can be unpredictable; and the abortion may even be incomplete, resulting in infections).

Abortion vs Contraception

The morning-after pill is a hormonal emergency birth control that prevents a pregnancy from occurring ideally within 72 hours of having unprotected sex. The contraception works by delaying and preventing ovulation.

On the other hand, the abortion pill is an abortion method that combines the use of two different medicines - mifepristone and misoprostol. The abortion pill can terminate a pregnancy of up to around 70 days. Mifepristone blocks the hormones that allow the pregnancy to develop, and misoprostol causes the uterus to contract strongly to expel the contents within.


The sooner you take the morning-after pill after unprotected intercourse, the more effective it will be. Taken within 24 hours of unprotected sex, the pill can reduce the chance of a pregnancy by up to 95%. If initiated within 72 hours, the effectiveness remains high at between 75-89%.

The abortion pill is proven to be effective in ending early pregnancies. However, Singapore abortion doctors may suggest a to complete the abortion because it is much safer, controlled and more comfortable.


The morning-after pill is generally safe and an established form of emergency birth control.

The abortion pill is generally considered to be a safe common procedure, but it carries potential risks and complications such as an incomplete abortion and severe bleeding and cramping. In Singapore, a surgical abortion is preferred by most doctors.

Side effects

The morning-after pill can cause side effects which can last for a few days including, nausea or vomiting, dizziness, fatigue, headache, breast tenderness, irregular bleeding, and abdominal pain or cramps.

The abortion pill has typical side effects such as abdominal pain, bleeding, dizziness, fatigue, changes in body temperature, and gastrointestinal discomfort.
