Choriogonadotropin Alfa

Indications

INDICATIONS AND USAGE Ovidrel ® PreFilled Syringe (choriogonadotropin alfa injection) is indicated for the induction of final follicular maturation and early luteinization in infertile women who have undergone pituitary desensitization and who have been appropriately pretreated with follicle stimulating hormones as part of an Assisted Reproductive Technology (ART) program such as in vitro fertilization and embryo transfer. Ovidrel ® PreFilled Syringe is also indicated for the induction of ovulation (OI) and pregnancy in anovulatory infertile patients in whom the cause of infertility is functional and not due to primary ovarian failure. Selection of Patients Before treatment with gonadotropins is instituted, a thorough gynecologic and endocrinologic evaluation must be performed. This should include an assessment of pelvic anatomy. Patients with tubal obstruction should receive Ovidrel ® PreFilled Syringe only if enrolled in an in vitro fertilization program. Primary ovarian failure should be excluded by the determination of gonadotropin levels.

Dosage and administration (summary)

DOSAGE AND ADMINISTRATION For Subcutaneous Use Only Infertile Women Undergoing Assisted Reproductive Technologies (ART) Ovidrel ® PreFilled Syringe 250 µg should be administered one day following the last dose of the follicle stimulating agent. Ovidrel ® PreFilled Syringe should not be administered until adequate follicular development is indicated by serum estradiol and vaginal ultrasonography. Administration should be withheld in situations where there is an excessive ovarian response, as evidenced by clinically significant ovarian enlargement or excessive estradiol production.

The risks of gonadoptropin treatment should be considered for women with risk factors of thromboembolic events such as prior medical or family history.
