DOSAGE AND ADMINISTRATION
The recommended dosage of ACTIMMUNE for the treatment of patients with Chronic Granulomatous Disease and severe, malignant osteopetrosis is 50 mcg/m2(1 million IU/m2) for patients whose body surface area is greater than 0.5 m2 and 1.5 mcg/kg/dose for patients whose body surface area is equal to or less than 0.5 m2. Note that the above activity is expressed in International Units (1 million IU/50mcg). This is equivalent to what was previously expressed as units (1.5 million U/50mcg). Injections should be administered subcutaneously three times weekly (for example, Monday, Wednesday, Friday). The optimum sites of injection are the right and left deltoid and anterior thigh. ACTIMMUNE can be administered by a physician, nurse, family member or patient when trained in the administration of subcutaneous injections. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
The formulation does not contain a preservative. A vial of ACTIMMUNE is suitable for a single dose only. The unused portion of any vial should be discarded.
Higher doses are not recommended. Safety and efficacy has not been established for ACTIMMUNE given in doses greater or less than the recommended dose of 50 mcg/m2. The minimum effective dose of ACTIMMUNE has not been established.
If severe reactions occur, the dosage should be modified (50 percent reduction) or therapy should be discontinued until the adverse reaction abates.
ACTIMMUNE may be administered using either sterilized glass or plastic disposable syringes.
