Postinor 2 is an emergency contraceptive pill (also known as the “morning-after pill”) used to prevent pregnancy after unprotected sex or contraceptive failure (e.g., condom breakage or missed birth control pills). It contains levonorgestrel, a synthetic hormone that works primarily by delaying or preventing ovulation.
How Does Postinor 2 Work?
Postinor-2 is most effective when taken as soon as possible after unprotected intercourse. Its mechanisms include:
-
Delaying or inhibiting ovulation (preventing the release of an egg).
-
Thickening cervical mucus, making it harder for sperm to reach an egg.
-
Not effective if implantation has already occurred (it does not cause abortion).
Effectiveness
-
Up to 95% effective if taken within 24 hours after unprotected sex.
-
85% effective if taken within 48-72 hours.
-
Less effective if ovulation has already happened.
Dosage & Usage
-
Two pills (0.75 mg levonorgestrel each):
-
Take one pill as soon as possible (within 72 hours).
-
Take the second pill 12 hours later.
-
-
Alternative: Some versions allow taking both pills at once.
Side Effects
Common side effects may include:
-
Nausea or vomiting
-
Fatigue or dizziness
-
Breast tenderness
-
Irregular menstrual bleeding
-
Headaches
Important Considerations
-
Not for regular contraception: Should only be used in emergencies.
-
Does not protect against STIs: Only prevents pregnancy.
-
Not 100% effective: If menstruation is delayed by over a week, a pregnancy test is recommended.
-
Not for frequent use: Repeated use can disrupt the menstrual cycle.
Who Should Avoid Postinor-2?
-
Women allergic to levonorgestrel.
-
Those already pregnant (it won’t work).
-
Women with severe liver disease.
