[1-14-2014] FDA has been informed of a brief shortage of Tamiflu Oral Suspension, an orally administered prescription medicine used to treat the flu. Tamiflu 30 mg, 45 mg, and 75 mg capsules remain available.
FDA would like to remind health care professionals of the FDA-approved instructions for how to prepare an oral suspension from the Tamiflu 75 mg capsules. These instructions are in the current package insert and are also found on the FDA drug shortages website.
Tamiflu is not a replacement for the annual flu vaccination, which comes in injectable and spray forms. There are currently no reported shortages of the flu vaccination: Influenza Virus Vaccine Safety & Availability.
Tamiflu Oral Suspension is manufactured by Genentech. Genentech expects to have additional Tamiflu Oral Suspension by mid-January 2014. Please check with authorized Genentech distributors and retailers for product availability.
Influenza antiviral drugs are commercially manufactured and supplies of these drugs are dependent upon those commercial manufacturers. FDA will continue to work with manufacturers to assess whether influenza antiviral supply issues arise this season.
