Powerful Prescription Antiviral Medicine for Flu Relief & Prevention

Oseltamivir Phosphate 45 mg Capsules by Lannett are a trusted, FDA-approved antiviral prescription medication uniquely designed to treat and prevent influenza (the flu) in adults and children. The active ingredient, oseltamivir phosphate (brand equivalent of Tamiflu), is clinically proven to decrease flu symptoms, shorten recovery time, and minimize flu-related complications when started promptly.

Uses (Indications):

  • Treatment of Influenza A & B: For patients showing flu symptoms for 2 days or less.
  • Prevention of Influenza: For individuals recently exposed to someone with the flu.

How to Use Oseltamivir Phosphate 45 mg Capsules:
