Abstract:
Pregnancy heightens the risk of adverse outcomes from influenza infections. This is true for both seasonal epidemics as well as occasional pandemics. Seasonal influenza vaccines are the focus of disease prevention and are recommended for all pregnant women in any trimester of pregnancy and postpartum. Oseltamivir (Tamiflu) is currently the recommended and most commonly used pharmaceutical agent for influenza prophylaxis and treatment. Oseltamivir has been demonstrated to prevent disease after exposure, treat infected individuals, as well as lessen the likelihood of complications. The physiologic adaptations of pregnancy alter the pharmacokinetics of this important drug. Evidence of these alterations, knowledge gaps, and future investigative directions to fill these knowledge gaps are highlighted.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
