NORISTERAT is a contraceptive injection primarily used by women to prevent pregnancy. It contains the synthetic progestogen, norethisterone enanthate, which works by inhibiting ovulation, altering the cervical mucus to prevent sperm penetration, and changing the lining of the uterus to prevent implantation of a fertilized egg. Administered via intramuscular injection, NORISTERAT provides effective contraception for 8 weeks, making it a suitable option for those seeking a short-term or medium-term contraceptive method. It is often chosen by women who cannot use estrogen-containing contraceptives or those who prefer not to take daily oral contraceptives. Like all medications, it may have side effects and is not suitable for everyone, so a healthcare provider's consultation is essential before starting NORISTERAT.
