<p>Based on findings from animal studies and its mechanism of action, Afatinib can cause fetal harm when administered to a pregnant woman. There are no available data on the use of Afatinib in pregnant women. Administration of afatinib to pregnant rabbits during organogenesis at exposures approximately 0.2 times the exposure in humans at the recommended dose of 40 mg daily resulted in embryotoxicity and, in rabbits showing maternal toxicity, increased abortions at late gestational stages [see Data]. Advise a pregnant woman of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.<br />

There are no data on the presence of afatinib in human milk or its effects on the breastfed infant or on milk production. Afatinib was present in the milk of lactating rats. Because of the potential for serious adverse reactions in nursing infants from Afatinib, advise a lactating woman not to breastfeed during treatment with Afatinib and for 2 weeks after the final dose.</p>
