DNase (Dornase Alfa) for Cystic Fibrosis
How It Works
The body's immune system uses white blood cells to fight infection. These cells release chemicals that kill both bacteria and surrounding normal cells. After attacking the bacteria, the white blood cells die, adding to the thickness of the mucus and damaging the lungs of people who have cystic fibrosis. Dornase alfa (DNase) helps liquefy and thin mucus by clearing out DNA from the dead white blood cells.
DNase is given through a nebulizer and is inhaled into the lungs.
Why It Is Used
DNase is used to thin and liquefy mucus in the lungs of children and adults with cystic fibrosis who have lung problems.
How Well It Works
DNase thins mucus so it can be coughed up more easily. It improves breathing and reduces the chance of infection.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
