Emergency contraceptives (e-pills) are one of the most commonly used drugs and hence commonly abused. There are also a lot of questions that go unanswered about these pills. Most often than not, those who use e-pills do so following advice from a friend and not a medical practitioner.

It is important to note that the pills are used in emergency cases and are not meant for use as a regular contraceptive. It should not be taken more than once within one menstrual cycle. It is recommended that an e-pill can be used once in 3months but only in case of an emergency. Otherwise, long term methods of contraception are available and one is advised to consult a doctor to determine which one will be suitable for them if they do not wish to get pregnant.


The first tablet should be taken as soon as possible and not later than72hours after unprotected intercourse. The second tablet should be taken 12hours after the first tablet and not later than 16hours. It is therefore important to work out the timing such that the time for the second tablet does not fall at odd times like at night when one is a sleep.

The two tablets may also be taken at the same time, preferably within 12hours after unprotected intercourse.

If one vomits within 3hours of taking either tablet, she may need an additional tablet.

An e-pill can be used on any day of the menstrual cycle.
