Gefitinib is also known as: Iressa

Overview

Do not become pregnant while taking Gefitinib. Gefitinib may cause harm to the fetus. If you become pregnant, discuss with your doctor the benefits and risks of using Gefitinib during pregnancy. It is unknown if Gefitinib is excreted in breast milk. Do not breast-feed while taking Gefitinib.

Gefitinib Pregnancy Warnings

Gefitinib has been assigned to pregnancy category D by the FDA. Animal studies have revealed evidence of reduced fetal weight, a reduction in the number of offspring born alive, and high neonatal mortality soon after parturition. There are no controlled data in human pregnancy. Gefitinib should only be given during pregnancy when there are no alternatives and benefit outweighs risk.

Women of childbearing potential must be advised to avoid becoming pregnant.

Gefitinib Breastfeeding Warnings

There are no data on the excretion of gefitinib into human milk. Because many drugs are excreted into human milk and because of the potential for serious adverse reactions in nursing infants, women should be advised against breast-feeding while receiving gefitinib therapy.
