IMPORTANT: NEBUPENT MUST BE DISSOLVED ONLY IN STERILE WATER FOR INJECTION, USP. DO NOT USE SALINE SOLUTION FOR RECONSTITUTION BECAUSE THE DRUG WILL PRECIPITATE. DO NOT MIX THE NEBUPENT SOLUTION WITH ANY OTHER DRUGS. DO NOT USE THE RESPIRGARD® II NEBULIZER TO ADMINISTER A BRONCHODILATOR.

Reconstitution

The contents of one vial (300 mg) must be dissolved in 6 mL Sterile Water for Injection, USP. Place the entire reconstituted contents of the vial into the Respirgard® II nebulizer reservoir for administration.

Dosage

The recommended adult dosage of NebuPent for the prevention of Pneumocystis jiroveci pneumonia is 300 mg once every four weeks administered via the Respirgard® II nebulizer.

The dose should be delivered until the nebulizer chamber is empty (approximately 30 to 45 minutes). The flow rate should be 5 to 7 liters per minute from a 40 to 50 pounds per square inch (PSI) air or oxygen source. Alternatively, a 40 to 50 PSI air compressor can be used with flow limited by setting the flowmeter at 5 to 7 liters per minute or by setting the pressure at 22 to 25 PSI. Low pressure (less than 20 PSI) compressors should not be used.

Stability

Freshly prepared solutions for aerosol use are recommended. After reconstitution with sterile water, the NebuPent solution is stable for 48 hours in the original vial at room temperature if protected from light.
