IMPORTANT PRODUCT STORAGE INFORMATION

Dear Health Care Provider:

This letter is to inform you of a recent change in the storage conditions for ORIMUNE®, Poliovirus Vaccine Live Oral Trivalent.

As outlined in the enclosed revised package insert (Revised: 8/24/99), the storage conditions are as follows:

"STORE IN FREEZER FOR MAXIMUM SHELF LIFE."

 

"To maintain the potency of ORIMUNE®, it is necessary to store this vaccine at a temperature that will maintain ice continuously in a solid state (below 0oC or 32oF). However, since the vaccine contains sorbitol it may remain fluid at temperatures above - 14oC (+7oF). Ice cubes that remain frozen continuously when stored in the same freezer compartment will confirm that the temperature is appropriate for storage of ORIMUNE®."
"Immediately prior to use remove an ORIMUNE® DISPETTE from the freezer, thaw completely and administer orally to patient."

Please note: Storage under refrigeration and repetitive freezing and thawing (freezer-thaw cycles) are no longer recommended.

If you need further assistance, please contact Wyeth Lederle Vaccines Biological Quality Assurance at 1-800-999-9384. Sincerely,

Raymond Shaw, Jr., Ph.D
Vice President, Quality Assurance
