This medicine usually comes with patient instructions. Read them carefully before using the medicine. If you do not understand the directions or you are not sure how to use the nebulizer, ask your doctor to show you how to use it.
Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. Also, do not stop using this medicine without telling your doctor. To do so may cause your lung condition to become worse.
Dornase alfa inhalation solution comes in small plastic containers called ampules. Each ampule contains one full dose of dornase alfa. Do not use an ampule that has already been opened.
Dornase alfa should be used with the eRapid™ nebulizer system or a jet nebulizer that is connected to an air compressor. An air compressor is used with a nebulizer to turn the medicine into a fine spray. You will breathe in the spray through your mouth.
Use the mouthpiece of the nebulizer to breathe in Pulmozyme®. Do not use a face mask with the nebulizer because less medicine will get into your lungs.
Patients who are unable to breathe in or breathe out by mouth may use the PARI BABY™ nebulizer with the supplied face mask. Make sure you understand exactly how to use this medicine in the nebulizer.
Do not use a cloudy or discolored inhalation solution.
You will need to use the nebulizer for about 10 to 15 minutes, or until the medicine in the nebulizer cup is gone.
Follow the manufacturer's directions for care and cleaning of the nebulizer and compressor.
In order to receive the full effects of this medicine, you must use it every day as ordered by your doctor. If possible, dornase alfa should be used at about the same time each day. You may notice some improvement in your condition within the first week of treatment. However, some patients may not feel the full effects of this medicine for weeks or months.
If you are taking any other medicines for cystic fibrosis, keep taking them as you did before you started using dornase alfa, unless otherwise directed by your doctor. However, do not put any other inhaled medicine in the nebulizer at the same time that you use dornase alfa. Other inhaled medicines may be used in a clean nebulizer before or after your treatment with dornase alfa.
The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
