CDC Releases Information for Antivirals Purchased Under Federal Contracts

The CDC is recommending that emergency antiviral drugs within state and local stockpiles not be used to treat seasonal influenza cases.

These drugs (Tamiflu and Relenza) purchased under government contracts have previously received an expiration date extension for up to 7 years.  In addition, the FDA is allowing the use of Tamiflu capsules from these stockpiles past the 7 year product shelf life.

Tamiflu capsules held in strategic stockpiles may now be used for a maximum of 10 years beyond manufacture date. FDA will not take enforcement action with regard to the storage or emergency use of these lots of Tamiflu capsules, provided that the products have been stored under labeled storage conditions.
