Per the manufacturer, Tamiflu suspension can be stored in the refrigerator or at room temperature, although refrigeration is preferred. Refrigeration of Tamiflu increases palatability of the suspension, making it more likely to be well tolerated by children and infants. In addition, refrigeration increases the shelf life of the product once mixed.


Storage Directions For Tamiflu Suspension


Pharmacy Storage (dry power before mixed):

Store dry powder 77ºF; excursions permitted from 59º to 86ºF. Product is good until the listed expiration date.


Reconstituted Suspension Storage (after mixed):

Store constituted suspension under refrigeration for up to 17 days at 36º F to 46º F.  Alternatively, the constituted suspension can be stored at room temperature (77ºF) for up to 10 days. Excursions are permitted in the range of 59º F to 86º F.


If the total prescribed duration of therapy is 10 days or less, the suspension that was left at room temperature may be used completely. You may store it under refrigeration to enhance the palatability of the product but as it was left out at room temperature, it will be considered expired after 10 days.
