Recommended Dose and Schedule

Administer ZOSTAVAX as a single 0.65-mL dose subcutaneously in the deltoid region of the upper arm.

Preparation for Administration

Use only sterile syringes free of preservatives, antiseptics, and detergents for each injection and/or reconstitution of ZOSTAVAX. Preservatives, antiseptics and detergents may inactivate the vaccine virus.

ZOSTAVAX is stored frozen and should be reconstituted immediately upon removal from the freezer.

When reconstituted, ZOSTAVAX is a semi-hazy to translucent, off-white to pale yellow liquid.

Reconstitution:

• Use only the diluent supplied.
• Withdraw the entire contents of the diluent into a syringe.
• To avoid excessive foaming, slowly inject all of the diluent in the syringe into the vial of lyophilized vaccine and gently agitate to mix thoroughly.
• Withdraw the entire contents of reconstituted vaccine into a syringe, inject the total volume subcutaneously, and discard vial.
• ADMINISTER IMMEDIATELY AFTER RECONSTITUTION to minimize loss of potency. Discard reconstituted vaccine if not used within 30 minutes. Do not freeze reconstituted vaccine.
