Emergency contraception is an important backup method to prevent pregnancy after unprotected sex or contraceptive failure. One of the most common emergency contraceptive pills in Nigeria is Postinor, often called the "post pill". At Mascot Healthcare, we want you to be informed, safe, and confident in your reproductive health decisions.
In this post, we’ll explain:
- What Postinor is
- When and how to take it
- Common side effects
- Myths and facts about emergency pills
- When to see a healthcare provider
What Is Postinor?
Postinor is an emergency contraceptive that contains levonorgestrel, a synthetic hormone that helps prevent pregnancy if taken shortly after unprotected sex. It is not meant for regular birth control use but is effective as a backup option.
There are two common types:
- Postinor-1: A single 1.5mg tablet
- Postinor-2: Two 0.75mg tablets taken 12 hours apart or both at once (depending on instructions)
How Does Postinor Work?
Postinor works mainly by:
- Delaying or preventing ovulation
- Altering cervical mucus to make it harder for sperm to reach an egg
- Changing the uterine lining to reduce the chance of implantation
Note: It does not terminate an existing pregnancy and is not an abortion pill.
When Should You Take It?
Postinor is most effective when taken as soon as possible after unprotected intercourse:
- Within 24 hours: Over 95% effective
- Within 72 hours: Still effective, but effectiveness drops with time
The earlier you take it, the better the result.
Possible Side Effects
Some people may experience mild side effects such as:
- Nausea or vomiting
- Fatigue or dizziness
- Breast tenderness
- Spotting or changes in the next period (earlier, later, heavier, or lighter)
- Lower abdominal pain
These usually resolve within a few days. If vomiting occurs within 2 hours of taking the pill, you may need to repeat the dose.
Common Myths and Facts
❌ Myth: Postinor causes infertility
✅ Fact: There is no evidence that occasional use of Postinor affects long-term fertility
❌ Myth: You can take it anytime during the month
✅ Fact: It's most effective before ovulation. If you’ve already ovulated, it may not work.
❌ Myth: It’s a regular birth control method
✅ Fact: Postinor is for emergency use only, not a replacement for routine contraception.
When to See a Doctor
Visit a healthcare provider if:
- Your period is more than 7 days late
- You experience severe abdominal pain
- You’re unsure if the pill worked
- You need advice on better long-term contraception
Final Thoughts from Mascot Healthcare
Postinor is a safe and effective emergency contraceptive when used correctly. It’s best to keep one handy in case of emergencies—but it’s not meant to replace regular methods like condoms, injectables, or birth control pills.
