Ovulation Induction

Rates of adverse events from a randomized, assessor-blind, group comparative, multi-center safety and efficacy study of Follistim® in 172 chronic anovulatory women who failed to ovulate and/or conceive during clomiphene citrate treatment are summarized in Table 6.

Table 6. Incidence of Adverse Clinical Experiences ( > 1%)

Adverse Event Follistim® (n=105)
Miscarriage 9.5%
Ovarian Hyperstimulation Syndrome 7.6%
Abdominal discomfort 2.9%
Abdominal pain, lower 2.9%

The following adverse events have been reported in women treated with gonado tropins: pulmonary and vascular complications (see WARNINGS), hemoperitoneum, adnexal torsion (as a complication of ovarian enlargement), dizziness, tachycardia, dyspnea, tachypnea, febrile reactions, flu-like symptoms including fever, chills, mus culoskeletal aches, joint pains, nausea, headache and malaise, breast tenderness, and dermatological symptoms (dry skin, erythema, body rash, hair loss, and hives)

There have been infrequent reports of ovarian neoplasms, both benign and malig nant, in women who have undergone multiple drug regimens for ovulation induction; however, a causal relationship has not been established.

Congenital Anomalies

The incidence of congenital malformations after Assisted Reproductive Technologies (ART) may be slightly higher than after spontaneous conception. This slightly higher incidence is thought to be related to differences in parental characteristics (e.g., maternal age, sperm characteristics) and to the higher incidence of multiple gestations after ART. There are no indications that the use of gonadotropins during ART is associated with an increased risk of congenital malformations.

Drug Abuse And Dependence

There have been no reports of abuse or dependence with Follistim® AQ (follitropin beta) (follitropin beta injection).
