Generally, pregnant women are not given antivirals unless the benefits clearly outweigh the risks to the fetus or neonate. As obligate intracellular parasites, the replication of viruses depends on synthetic processes of the host cell. Antiviral drugs can exert their actions at several stages of viral replication including viral entry, nucleic acid synthesis, late protein synthesis and processing, and in the final stages of viral packaging and virion release (Figure 49–1). .
