What Postrelle-1 is used for
Postrelle-1 is an emergency contraceptive only. Postrelle-1 is not intended as a regular method of contraception.
It contains the active ingredient levonorgestrel.
It is used to prevent pregnancy when taken within 72 hours of unprotected intercourse. It is estimated that Postrelle-1 will prevent 85% of expected pregnancies. The sooner that you take Postrelle-1 after unprotected intercourse, the more likely it is that the medicine will work.
Postrelle-1 is thought to work by:
stopping your ovaries from releasing an egg
preventing sperm from fertilising any eggs you may have already released
stopping a fertilised egg from attaching itself to your womb lining.
Therefore, Postrelle-1 stops a pregnancy before it is established. It does not work if you are already pregnant.
Postrelle-1 will not prevent you from catching sexually transmitted diseases.
Ask your doctor or pharmacist if you have any questions about why you are taking Postrelle-1.
This medicine is not addictive.

How to take Postrelle-1

Swallow the tablet whole with a full glass of water.
If you are already using a regular method of contraception such as the contraceptive pill, you can continue to take this at your regular time.
Your doctor or pharmacist should advise you to use a barrier contraception method until your next period.
