Pregnant women are at increased risk of severe complications associated with H1N1 pandemic influenza. Fever and inflammatory syndrome associated with the infection may also be deleterious for the developing fetus. Therefore, early antiviral treatment is recommended. Oseltamivir and zanamivir are the two therapeutic options available indicated in the treatment of H1N1 influenza; however, limited data is published on their use during pregnancy and lactation. In this review, we will focus on the effects of H1N1 during pregnancy and on data safety of antivirals during pregnancy and lactation. Main health authorities recommendations for H1N1 influenza treatment of pregnant women will also be presented.
