What is Norifam?
Norifam is a combined injectable contraceptive (CIC) administered monthly to prevent pregnancy. It contains two active hormones: Norethisterone enanthate (a progestin) and Estradiol Valerate (an estrogen). These hormones are released gradually from an oily solution after injection, providing continuous contraception for 30 days and eliminating the need for a daily pill.
The Mechanism of Action: How Norifam Works
Norifam prevents pregnancy through several actions:
- Inhibiting Ovulation: The hormones suppress the release of FSH and LH, crucial for egg release.
- Thickening Cervical Mucus: This makes it harder for sperm to reach the uterus.
- Altering the Endometrium: Changes in the uterine lining make implantation of a fertilized egg more difficult.
Norifam's Primary Indication: Pregnancy Prevention
Norifam's sole approved use is to prevent pregnancy. It is an effective contraceptive option.
Benefits and Potential Side Effects
Considering Norifam involves weighing its benefits against potential side effects. Some benefits include monthly convenience and potentially more regular menstrual cycles compared to some other options. Potential side effects can include menstrual irregularities, weight changes, and headaches.

How Norifam Compares to Other Injectable Contraceptives
Norifam differs from other injectable contraceptives, such as 3-month progestin-only injections (like DMPA), in its composition and schedule.
| Characteristic | Norifam (Combined Injectable) | Progestin-Only Injectable (e.g., DMPA) |
|---|---|---|
| Hormonal Composition | Contains both estrogen and progestin. | Contains only progestin. |
| Injection Frequency | Monthly (every 30 ± 3 days). | Every 3 months. |
| Bleeding Pattern | Tends towards more regular cycles over time, though initial irregularities are common. | Irregular bleeding common initially, with many users experiencing no monthly bleeding after a year. |
| Average Weight Gain | Approximately 1 kg per year. | {Link: norifam.com https://norifam.com/frequently-asked-questions-and-norifam-reviews/}. |
| Window for Injection | 7 days before or after the scheduled date. | {Link: norifam.com https://norifam.com/frequently-asked-questions-and-norifam-reviews/}. |
| Return to Fertility | Can be delayed (average 5 months) but potentially quicker than some progestin-only options. | Can take several months after stopping. |
Important Considerations and Contraindications
A medical evaluation is necessary before using Norifam to ensure it's safe. It should not be used in certain situations, including pregnancy, a history of blood clots, severe liver disease, hormone-dependent cancers, severe high blood pressure, and migraine with aura. It is also not recommended for smokers over 35 or for exclusively breastfeeding mothers, especially in the first six weeks postpartum.
Conclusion
What is Norifam used for? Primarily, it is a highly effective, once-a-month injectable contraceptive designed to prevent pregnancy through a combination of hormonal actions. It offers a convenient alternative to daily pills and is associated with more regular menstrual bleeding than some progestin-only injectables. While it provides reliable protection, potential users must be aware of its benefits, common side effects, and specific contraindications related to conditions like blood clots, liver disease, and specific types of migraines. Consulting with a healthcare provider is essential to determine if Norifam is a safe and appropriate choice for individual family planning needs {Link: norifam.com https://norifam.com/frequently-asked-questions-and-norifam-reviews/}.
