Warnings
Contraindications
Pregnancy; may cause fetal harm
Hypersensitivity
High levels of FSH indicating primary ovarian failure
Presence of uncontrolled nongonadal endocrinopathies (eg, thyroid, adrenal, or pituitary disorders)
Sex hormone dependent tumors of the reproductive tract and accessory organ
Tumors of pituitary gland or hypothalamus
Abnormal uterine bleeding of undetermined origin
Ovarian cysts or enlargement of undetermined origin, not due to polycystic ovary syndrome
Cautions
Should be administered only by physicians thoroughly experienced in fertility disorders
Hypersensitivity/anaphylactic reactions reported
Ovarian hyperstimulation syndrome (OHSS) reported; OHSS is a medical event distinct from uncomplicated ovarian enlargement and may progress rapidly to become a serious medical event; characterized by dramatic increase in vascular permeability, which can result in a rapid accumulation of fluid in the peritoneal cavity, thorax, and potentially, the pericardium
Use lowest effect dose to minimize abnormal ovarian enlargement; if ovaries are enlarged on last day of therapy, do not administer hCG because of risk for OHSS
May cause pulmonary and vascular complications (eg, atelectasis, ARDS)
Ovarian torsion has been reported after treatment with gonadotropins
Multi-fetal gestation and births have been reported with all gonadotropin therapy
Incidence of congenital malformations after some ART (specifically IVF or ICSI) may be slightly higher than after spontaneous conception (likely due to parental characteristics)
Since infertile women undergoing ART often have tubal abnormalities, the incidence of ectopic pregnancy may be increased
Increased incidence of spontaneous abortion and ovarian neoplasms observed (without causality)
Pregnancy & Lactation
Pregnancy Category: X
Lactation: Not known whether drug is excreted in breast milk; use caution
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
