  • To use this medicine:
    • Use the vials only in a standard jet nebulizer machine with a mouthpiece connected to an air compressor. Do not swallow or inject the liquid in the vial. Do not mix this medicine with any other medicine in your nebulizer.
    • Do not remove the vial from the sealed pouch until you are ready to use it. Use the vial right away once you have opened the pouch.
    • Check the liquid in the vial. It should be clear and colorless. Do not use it if it is discolored.
    • Squeeze all of the medicine from the vial into the nebulizer cup.
    • Connect the mouthpiece to the nebulizer cup with the expiratory valve facing up.
    • Insert one end of the tubing to the compressor and the other end to the bottom of the nebulizer cup.
    • Sit in an upright position. Place the mouthpiece in your mouth and close your lips around it. Turn on the compressor.
    • Take one long, steady, deep breath in through your mouth until no more mist is seen in the nebulizer cup. Your treatment will take about 8 minutes and will end when you do not see any mist in the nebulizer anymore. Turn the compressor off.
  • This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.
