Do not administer intravenously.
Dose: See table.

Preparation and Handling: If the product shows any sign of tampering, do not use it and notify Grifols Therapeutics LLC immediately.
Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. GAMASTAN is a clear or slightly opalescent, and colorless to pale yellow or light brown sterile solution.
Administration: Administer GAMASTAN intramuscularly, preferably in the anterolateral aspects of the upper thigh and the deltoid muscle of the upper arm. Do not use the gluteal region as an injection site because of the risk of injury to the sciatic nerve. (See Precautions.)
Draw back on the plunger of the syringe before injection in order to be certain that the needle is not in a blood vessel. (See Precautions.)
Divide and inject doses greater than 10 mL into several muscle sites to reduce local pain and discomfort. An individual decision as to which muscle is injected must be made for each patient based on the volume of material to be administered.
If Hepatitis A Vaccine is recommended along with GAMASTAN, administer simultaneously but at separate anatomical sites.
