Below you will find more information on the Lydia Postpil. If you can't find the information you are looking for, make sure you ask the Lydia Contact Centre.
The Lydia Postpil is an emergency contraceptive for prevention of pregnancy following unprotected intercourse or if you were forced into having sex (rape) or after a known or suspected contraceptive failure, such as: when a condom breaks or you missed taking your regular contraceptive pills or injections or you did not abstain from sex during your fertile period, etc.
Lydia Postil can be used by women of all reproductive ages including adolescents.
Each film-coated tablet contains Levonorgestrel 750 mcg
The Lydia Postpil mainly acts by preventing the release of an egg (ovulation) or by stopping the egg and sperm from meeting (Fertilization) through altering tubal transport of sperm and egg. In addition, it may inhibit implantation by altering the endometrium but it is not effective once the process of implantation has begun.
The Lydia Postpil is contra-indicated for use in the case of known or suspected pregnancy or if you are hypersensitive to Levonorgestrel.
Each pack contains a single blister with two tablets of Lydia Postpil (Levonorgestrel 750 mcg) along with a package insert.
There are two possible ways of taking the Lydia Postpil:
1. Take the two tablets of Lydia Postpil orally at the same time, or
2. Take one tablet as soon as possible and the second tablet 12 hours later
Take the Lydia Postpil as soon as possible (preferably within 24 hours), but not later than 120 hours (5 days) after unprotected sex, rape or suspected contraceptive failure. The earlier you take the Lydia Postpil the more effective it will be.
If you vomit within two hours of taking the tablets, you should repeat the dose. It can be used at anytime during your menstrual cycle.
Emergency contraceptives like the Lydia Postpil prevent pregnancy by delaying ovulation and are most effective within the first 24 hours (1 day) after unprotected sex. The Lydia Postpil is only effective for the unprotected sex prior to taking the pills. If you have unprotected sex again after taking the Lydia Postpil, you may be at risk of pregnancy, because active sperm could be waiting in the fallopian tubes when the egg is eventually released, therefore always use another form of contraception (condom/pills) after you have taken the Lydia Postpil.
Please note that even if multiple acts of unprotected sex occur in a day, the Lydia Postpil should not be taken more than once within 24 hours (except when vomiting within 2 hours of taking the tablets). Subsequently, it is recommended you begin a regular short or long term method of contraception the day after taking the Lydia Postpil. You should consult a health care professional for advice on choosing a methods most suitable to you.
Repeated use of the Lydia Postpil or any other emergency contraceptive poses no known health risks. It is medically safe. You may have menstrual changes such as shorter/longer cycles and have a heavier/lighter period than normal and other side effects mentioned in this leaflet should be anticipated. However, it is recommended that you use a regular contraceptive method as it is the ‘most effective’ way to prevent pregnancy. You should consult a healthcare professional for advice on choosing a regular method most suitable to your needs.
Extensive medical research and many years of monitoring have shown that emergency contraceptives such as the Lydia Postpil are safe.

Emergency contraception is a safe and important option for preventing unwanted pregnancies, but is NOT a regular contraceptive method.
