Literature on the outcome of pregnancy after exposure to capecitabine and temozolomide during the first trimester is scarce. Chemotherapy administration in the first trimester is generally not recommended due the potential risks to the fetus including fetal death and major congenital malformations. Capecitabine and temozolomide are oral chemotherapy agents and pregnancy category D medications, thus the use of these agents in pregnancy is not recommended. We present the case of a 17-year-old female who while receiving cancer treatment, had unintentional exposure to capecitabine and temozolomide during the first trimester of pregnancy, and subsequently delivered a healthy infant.
