For many women and young people, the injection is an empowering choice because it requires no daily routine and provides months of protection at a time.

Pro Tip: Always consult a healthcare provider before starting or switching contraceptive methods. Nurses at HealthPosts are available to offer counseling and guidance on whether the contraceptive injection is the right option for you.


How the Contraceptive Injection Works

The injection contains a hormone called progestin, which prevents pregnancy in three main ways:

  1. Stops ovulation – no egg is released from the ovary.
  2. Thickens cervical mucus – making it difficult for sperm to reach the egg.
  3. Thins the uterine lining – reducing the chances of implantation.

When administered on time, the injection is over 99% effective, making it one of the most reliable contraceptive methods available.


Types of Contraceptive Injections

There are two main types of contraceptive injections:

  • Depo-Provera (DMPA): Given every 12 weeks (3 months).
  • Noristerat: Given every 8 weeks (2 months).

Both work in a similar way but differ in duration and dosage schedule.


 

 

Benefits of the Injection

Long-lasting protection (2–3 months per dose)
Highly effective when given on schedule
Discreet and convenient (no daily pill to remember)
Can reduce menstrual cramps and bleeding
Suitable for women who cannot use estrogen-based contraceptives


Possible Side Effects

Like any medical method, the contraceptive injection may have some side effects, including:
• Irregular bleeding or spotting (common at the beginning)
• Changes in weight
• Headaches or mood changes
• Delay in return to fertility after stopping (usually within 6–12 months)

These side effects often lessen over time. A healthcare provider can help manage them if they persist.


Common Myths About the Injection

🚫 Myth: The injection causes permanent infertility.
Fact: Fertility usually returns after stopping, though it may take several months.

🚫 Myth: It works immediately after stopping menstruation.
Fact: Timing matters—the first injection is most effective if given within the first 7 days of a woman’s menstrual cycle.

🚫 Myth: It protects against STIs.
Fact: The injection only prevents pregnancy—condoms are still needed for STI protection.


Accessibility for Youth

The contraceptive injection is widely available at health facilities, pharmacies, and youth-friendly centers. HealthPosts provide:
• Free or low-cost injections
• Confidential and judgment-free services
• Counseling to help young people make informed choices


Conclusion

The contraceptive injection is a reliable, convenient, and empowering method of preventing pregnancy. With timely doses and proper guidance, it offers months of protection while giving individuals more control over their reproductive health. However, since it does not prevent sexually transmitted infections, using it together with condoms is the safest approach.
