For confirmed or suspected influenza, Ogaei physicians can prescribe neuraminidase inhibitor antivirals, with oseltamivir (Tamiflu) being the most commonly prescribed option in Canada. Taken orally twice daily for 5 days, Tamiflu works by preventing flu viruses from spreading within your respiratory tract. When started within 48 hours of symptom onset, it can reduce illness duration by approximately one day and decrease symptom severity. Alternative antivirals include zanamivir (Relenza), an inhaled powder, or baloxavir marboxil (Xofluza), a convenient single-dose option. Your doctor will recommend the most appropriate medication based on your specific situation, medical history, and symptom timeline. These medications work best when started early, which is why rapid medical consultation matters.
