This vaccine may not work as well if you are also using these medicines. Your doctor may still want you to get the vaccine because it can give you some protection.
  • Make sure you doctor knows if you are also using medicine to treat influenza virus infections (such as amantadine, oseltamivir, rimantadine, zanamivir, Flumadine®, Relenza®, Symmetrel®, or Tamiflu®). Wait at least 48 hours after your last dose of antiviral medicine before you receive FluMist®.
