This drug is considered a potential human teratogen because of its mechanism of action and the developmental effects demonstrated by related agents. Studies in animals during the organogenesis period of gestation were associated with fetal growth retardation and an increased incidence of premature delivery at doses 0.01 times the recommended human dose on a mg/m2 basis. No teratogenic effects were observed in these studies, but the maximum doses tested were well below the recommended human dose. There are no controlled data in human pregnancy.

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.

US FDA pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
