Interferon gamma
Dosing in kidney impairment
Hypersensitivity Reactions: If serious hypersensitivity reactions occur, discontinue and institute appropriate medical therapy. Renal Toxicity : Monitor renal function regularly when administering ACTIMMUNE to patients with severe renal insufficiency 5.1 Cardiovascular Disorders Acute and transient "flu-like" symptoms such as fever and chills induced by ACTIMMUNE at doses of 250 mcg/m 2 /day (greater than 10 times the weekly recommended dose) or higher may exacerbate pre-existing cardiac conditions.
If such an acute reaction develops the drug should be discontinued immediately and appropriate medical therapy instituted. Transient cutaneous rashes have occurred in some patients following injection of ACTIMMUNE that have necessitated treatment interruption. 5.6 Renal Toxicity Monitor renal function regularly when administering ACTIMMUNE in patients with severe renal insufficiency because the possibility exists that with repeated administration, accumulation of interferon gamma-1b may occur.
Renal toxicity has been reported in patients receiving ACTIMMUNE. 5.7 Allergic Reactions to Natural Rubber The stopper of the glass vial for ACTIMMUNE contains natural rubber (a derivative of latex) which may cause allergic reactions.

Important Administration Instructions The optimum sites of subcutaneous injection are the right and left deltoid and anterior thigh. ACTIMMUNE can be administered by a physician, nurse, family member or patient when appropriately counseled 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.
ACTIMMUNE is a clear, colorless solution. ACTIMMUNE is for a single dose only. Discard any unused portion. ACTIMMUNE does not contain a preservative. ACTIMMUNE should not be mixed with other drugs in the same syringe. Administer ACTIMMUNE using either sterilized glass or plastic disposable syringes.

Concomitant use of drugs with neurotoxic, hematotoxic or cardiotoxic effects may increase the toxicity of interferons. ( 7.2 ) Avoid simultaneous administration of ACTIMMUNE with other heterologous serum protein or immunological preparations (e.g., vaccines). ( 7.3 )
7.1 Myelosuppressive Agents When administering ACTIMMUNE in combination with other potentially myelosuppressive agents, monitor neutrophil and platelet counts [see Warnings and Precautions (5.3) ] .
7.2 Drugs with Neurotoxic, Hematoxic or Cardiotoxic Effects The concurrent use of drugs having neurotoxic (including effects on the central nervous system), hematotoxic, or cardiotoxic effects may increase the toxicity of interferons in these systems. It is theoretically possible that hepatotoxic and/or nephrotoxic drugs might have an effect on the clearance of ACTIMMUNE.
7.3 Immunological Preparations Simultaneous administration of ACTIMMUNE with other heterologous serum protein preparations or immunological preparations (e.g., vaccines) should be avoided due to the risk of an unexpected, or amplified, immune response.
7.4 Effects on Cytochrome P-450 Pathways Preclinical studies in rodents using species-specific interferon gamma have demonstrated a decrease in hepatic microsomal cytochrome P-450 concentrations. This could potentially lead to a depression of the hepatic metabolism of certain drugs that utilize this degradative pathway.
Contraindications
4 CONTRAINDICATIONS ACTIMMUNE is contraindicated in patients who develop or have known hypersensitivity to interferon gamma, E. coli derived products, or any component of the product. Known hypersensitivity to interferon gamma, E. coli derived products, or any component of the product ( 4 )
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies in pregnant women. ACTIMMUNE should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal Data ACTIMMUNE has shown an increased incidence of abortions in primates when given from gestation day 20 to 80 in doses approximately 100 times the human dose. A study in pregnant primates treated with subcutaneous doses 2 – 100 times the human dose failed to demonstrate teratogenic activity for ACTIMMUNE.
Female mice treated subcutaneously with recombinant murine IFN-interferon gamma (rmuIFN-gamma) at 280 times the maximum recommended clinical dose of ACTIMMUNE from shortly after birth through puberty but not during pregnancy had offspring which exhibited decreased body weight during the lactation period. The clinical significance of this finding observed following treatment of mice with rmuIFN-gamma is uncertain. For lower doses, there is no evidence of maternal toxicity, embryotoxicity, fetotoxicity or teratogenicity in preclinical studies.
