SWINE FLU (INFLUENZA H1N1)
FDA is authorizing the use of certain lots of expired Tamiflu for Oral Suspension as part of the federal government’s response to the 2009 H1N1 Influenza public health emergency.
In July 2009, FDA authorized 4 lots of Tamiflu for Oral Suspension for use beyond their labeled expiration dates. FDA is now authorizing additional lots in an effort to ensure that Tamiflu for Oral Suspension is available for patients during this public health emergency. The lots of Tamiflu for Oral Suspension that are being authorized are part of the Strategic National Stockpile and have been tested through the federal government’s Shelf-Life Extension Program (SLEP).
Under SLEP, FDA conducts scientific testing and analysis to determine if certain drugs are acceptable for use beyond their expiration date. During testing, FDA comprehensively evaluates each lot to assure the quality and stability of the product. Through the SLEP testing process, FDA has determined that data support the use of these lots of Tamiflu for Oral Suspension beyond their expiration dates.
The lots of Tamiflu for Oral Suspension now authorized by FDA for use beyond their expiration dates are not required to be relabeled with information about the use of the products beyond their expiration dates. Therefore, healthcare professionals and patients might receive Tamiflu for Oral Suspension that is beyond its expiration date. In addition, fact sheets for both patients and healthcare professionals will be made available by public health officials. These fact sheets will contain information about the authorized use of these products beyond their expiration dates.
These decisions to authorize the use of certain lots of Tamiflu for Oral Suspension beyond their expiration dates are based on rigorous scientific testing and analysis. Healthcare professionals may wish to discuss this information with patients to inform them that the medication they have been given is authorized for use based on scientific testing and analysis.
