What is Ella pill? – Emergency Contraception Singapore

The Ella pill (ulipristal) is a type of emergency oral contraception, known also as the “morning-after pill”. It is relatively safe and effective, and lowers the chance of unintended pregnancy by about 85 percent if taken within 5 days after unprotected sex. The sooner you take the pill, the more effective it is.

Ella pill works by delaying or preventing ovulation i.e. release of an egg. It may also make it harder for a fertilised egg to attach to the uterus. If you are already pregnant, it will have no effect on termination of your existing pregnancy. Do not use it if you are already pregnant or if you might be pregnant.


When does Ella pill not work?

If your next menses is more than one week late, or missed entirely, you will require a pregnancy test to make sure you are not pregnant.


What are the side effects of the pill?

The most common side effects of Ella are headache, nausea and lethargy. If vomiting occurs within 2-3 hours after taking the pill, a second dose of the pill may be required.
