Norethisterone Enanthate Description and Indication

Norethisterone Enanthate is used as an Injectable contraceptive for a period of 1-3 months and resembles the natural female progesterone. Each dose contains 200mg of hormone in an oily base. It can be the ideal post-vasectomy contraceptive when contraception is still required for 2-3 months. It provides safe and effective contraception after delivery and/or abortion. It is also suitable for women who may have side effects related to the use of contraceptives containing estrogen.

As mentioned, Norethisterone Enanthate is indicated for injectable hormonal contraception. It is particularly suitable for women who cannot take oral contraceptives regularly or who do not tolerate them well. Norethisterone Enanthate should only be administered to women with a history of normal cycles.

Norethisterone Enanthate Mechanism of Action

The drug disrupts follicular maturation and rupture via a central mechanism, provided that it is present at a certain plasma level such as that achieved with Norethisterone over 5 to 7 weeks after the injection. When it is injected, conception cannot take place during this period because no ovum is available to be fertilized. The cervical mucus is under the influence of the progestogen throughout the entire injection interval. It causes the lining of the endometrium to become thinner, so fertilized eggs can’t attach them to it.

Norethisterone Enanthate Dosage

Norethisterone Enanthate is administered by intramuscular injection; a dose of 200 mg provides contraception for 8 weeks.
