Bendamustine Pregnancy Warnings

Animal studies have revealed single intraperitoneal doses causing embryofetal lethality, increased fetal skeletal and visceral malformations, and decreased fetal body weights. Impaired spermatogenesis, azoospermia, and total germinal aplasia have been reported in males treated with alkylating agents, especially in combination with other drugs. Spermatogenesis may return in patients in remission, but only several years after intensive chemotherapy has been discontinued. 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 Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
