What You Need to Know Before Taking Emergency Contraceptive pills

Postinor (levonorgestrel 1.5 mg) is an emergency contraceptive used to prevent pregnancy after unprotected sex or contraceptive failure. It works by delaying ovulation, preventing the release of an egg, and making the uterine lining less receptive to a fertilized egg. Unlike regular contraceptives, Postinor (levonorgestrel) is a single-use emergency solution, not for consistent use.

Key Factors That Affect Emergency Contraceptive pills Effectiveness:

• Delayed Use: It works best when taken promptly.

  Within 24 hours: ~95% effective

  24–48 hours: ~85% effective

  48–72 hours: ~58% effective
  After 72 hours, its effectiveness is minimal.

• Ovulation Timing: It delays ovulation, so it may not work if intercourse occurs during or after ovulation.
• Vomiting After Taking Postinor: If vomiting occurs within two hours of taking the pill, its active ingredients may not be absorbed. A replacement dose may be necessary.
• Drug Interactions: Medications like rifampicin, carbamazepine, or phenytoin, and herbal supplements like St. John’s Wort, can reduce Postinor’s (levonorgestrel) effectiveness.
• Body Weight and BMI: Effectiveness may decrease in individuals with a BMI over 30. In such cases, a copper IUD may be a more reliable option.
• Multiple Unprotected Intercourse Events: A pill like postinor (levonorgestrel) is for single-use scenarios. It does not offer protection against subsequent unprotected intercourse.
• Pre-existing Pregnancy: Emergency contraceptive pills cannot terminate an existing pregnancy; it only prevents fertilization or implantation.
• Improper Storage or Expired Medication: Always store these pills as directed and check expiration dates to ensure effectiveness.

Preventing overuse

• Frequent use of emergency contraceptive can lead to hormonal imbalances and menstrual irregularities. Prevent overuse by:
  • Using Regular Contraception: Consider long-term options like birth control pills, IUDs, or implants.
  • Practicing Safe Sex: Consistent use of condoms reduces the need for emergency contraception.
  • Seeking Guidance: Consult a healthcare professional for tailored contraceptive advice.

CONCLUSION

Emergency contraceptive pills like postinor (levonorgestrel) are reliable but should not replace regular contraception. Consistent use of options like birth control pills, IUDs, or condoms provides better protection against unintended pregnancies.

Understanding their limitations and proper use ensures maximum effectiveness and reduces stress. For personalized advice, always consult a healthcare professional.
