General

The more commonly reported adverse reactions have included injection site redness and/or swelling, abdominal pain, and headache; rare postmarketing cases of anaphylaxis have been reported.[Ref]

Endocrine

Among 283 newborns of mothers receiving this drug; 3 neonates had major congenital anomalies (i.e., hydrocephalus/meningocele, omphalocele, and Beckwith-Wiedemann Syndrome) and 18 neonates experienced minor anomalies (i.e., nevus, skin tags, sacral sinus, hemangioma, torticollis/asymmetric skull, talipes, supernumerary digit finger, hip subluxation, torticollis/high palate, occiput/abnormal hand crease, hernia umbilicalis, hernia inguinalis, hydrocele, undescended testis, and hydronephrosis). A subsequent analysis showed the incidence of congenital anomalies with this drug are comparable to another GnRH agonist.

The incidence of congenital malformations after Assisted Reproductive Technology appears to be slightly higher than after spontaneous conception; although this may be related to differences in parental characteristics and higher incidence of multiple gestations.
