Contraceptive Injections

Contraceptive injections work by injecting synthetic hormones into a woman’s body, which suppress ovulation, thicken cervical mucus to make it difficult for sperm to pass through, and alter the uterine lining to prevent a fertilized egg from implanting. Like birth control pills, contraceptive injections are available in both progestin-only and combined hormonal forms. Most women opt for the progestin-only injection, which is effective for up to three months. Although the combined hormonal injection is equally effective, it requires monthly injections.

Where Can I Get the Injection?

You can consult a doctor and receive the injection at private clinics, Family Planning Association centers, or youth health centers. The Department of Health’s Maternal and Child Health Centers also offer consultation services, where healthcare professionals provide suitable contraceptive methods based on individual needs, including condoms, birth control pills, contraceptive injections, intrauterine devices (IUDs), and emergency contraception. Remember to attend regular follow-up appointments and injections, which are usually administered in the buttocks or arm.

During a consultation with healthcare professionals, you can expect:

  • A few questions about your medical history and family history to determine the most suitable method for you
  • Informing the healthcare provider of any other medications you are taking to ensure they do not interfere with the injection
  • The doctor or nurse will check your blood pressure and weight

How to Use

If you are sure you are not pregnant, you can get the injection at any time during your menstrual cycle. If you receive the injection within the first five days of your period, you will be immediately protected from pregnancy. Be sure to follow the healthcare provider’s instructions and attend regular follow-up appointments and injections.
