Caution: A sterile syringe free of preservatives, antiseptics, and detergents should be used for each injection and/or reconstitution of refrigerator-stable VARIVAX because these substances may inactivate the vaccine virus.
It is important to use a separate sterile syringe and needle for each patient to prevent transmission of infectious agents from one individual to another.
To reconstitute the vaccine, use only the diluent supplied with refrigerator-stable VARIVAX, since it is free of preservatives or other anti-viral substances which might inactivate the vaccine virus.
Do not freeze reconstituted vaccine.
Do not give immune globulin, including Varicella Zoster Immune Globulin, concurrently with refrigerator-stable VARIVAX (see also Precautions).
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Refrigerator-stable VARIVAX when reconstituted is a clear, colorless to pale yellow liquid.
Stability: Refrigerator-stable VARIVAX has a minimum potency level of approximately 1350 PFU 30 minutes after reconstitution at room temperature (20 to 25°C, 68 to 77°F).
