It appears that the 2017-2018 influenza season will be a rough one based on early reports. The Centers for Disease Control and Prevention (CDC) reported in their most recent Weekly Influenza Report that influenza activity increased sharply in the United States. In fact, widespread influenza activity was reported by 46 states.

With this season’s flu vaccine showing reduced effectiveness, the demand for flu antivirals may be increased.

The CDC published the following yesterday concerning the antiviral drug supply:

Manufacturers have stated they have sufficient product on hand to meet projected demand for the 2017-2018 flu season.
As influenza antiviral drugs are mainly used seasonally, patients may want to consider calling a pharmacy in advance to see if they have drug on their shelf. If the pharmacy does not have product, they may be able to identify another pharmacy in the area that has antiviral drugs in stock.

CDC will update this page as needed with respect to influenza antiviral supply this season.
