Nebulizer Treatment

Dornase comes as a liquid and needs to be made into a mist so it can go deep into your lungs. Certain equipment must be used to deliver Dornase properly. The air compressors that can be used to do this are called, Pulmo-Aide®, Medimist®, Inspiration®, or Pari-Proneb®.

The nebulizers that can be used are called Marquest Acorn II® disposable, Hudson T Updraft II® disposable, Sidestream® disposable, Sidestream® reusable or PariLC Jet®.

Using Dornase

First wash your hands with soap and warm water, or use anti-bacterial hand gel, to reduce the risk of infection.

A Dornase nebulizer must never be used for any other medicine. If not cleaned properly, Dornase drug left in the nebulizer can form a thick substance and clog up the nebulizer and reduce the amount of medicine sent to the lungs.

  1. Place the contents of one vial of Dornase in the nebulizer cup and throw the empty vial away.

  2. Take a slow deep breath and hold for 5 seconds every few breaths. Holding your breath helps the Dornase deposit in your lungs.

  3. The treatment will last between 6-12 minutes depending on the type of nebulizer and air compressor you use.

Clean and Disinfect the Nebulizer

Dornase can cause bacterial contamination to the lungs if not cleaned and disinfected daily. To clean and disinfect by hand, you can use either vinegar and water method or rubbing alcohol method. If you have Cystic Fibrosis (CF) do not use the vinegar and water method. To make sterile water boil for 5 minutes. Do not use water from the faucet, bottled or distilled. Use this water only once.

Vinegar and Water Method

Take the nebulizer apart. Wash the pieces in warm soapy water and rinse with hot tap water. Place the pieces in a bowl and add enough vinegar and water solution to completely cover the equipment. Make the mixture of 1 cup vinegar to 2 cups water. Soak the nebulizer for 30 minutes to 2 hours. Rinse all parts of the nebulizer with sterile water. Place the pieces on a paper towel to dry.

Rubbing Alcohol Method

How do I clean and disinfect in the dishwasher?
