Dornase Alfa

Why is this medication prescribed?

Dornase alfa is used to reduce the number of lung infections and to improve lung function in patients with cystic fibrosis. It breaks down the thick secretions in the airways, allowing air to flow better and preventing bacteria from building up.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Dornase alfa comes as a solution to inhale by mouth. It usually is taken one or two times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use dornase alfa exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Dornase alfa is used to treat cystic fibrosis but does not cure it. Continue to use dornase alfa even if you feel well. Do not stop using dornase alfa without talking to your doctor.

Before you use dornase alfa the first time, read the written instructions that come with it. Ask your doctor, pharmacist, or respiratory therapist to demonstrate the proper technique. Practice using the nebulizer while in his or her presence. Only use a nebulizer that is recommended by your doctor.

What special precautions should I follow?

Before using dornase alfa,

  • tell your doctor and pharmacist if you are allergic to dornase alfa or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using dornase alfa, call your doctor.

What should I do if I forget a dose?

Use the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not use a double dose to make up for a missed one.

Do not expose the drug to room temperature for more than 24 hours. Any ampule that has been open for more than 24 hours should be discarded. Discard ampules if the solution is cloudy or discolored. Talk to your pharmacist about the proper disposal of medicine that is outdated or no longer needed.

What other information should I know?

Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your response to dornase alfa.

Do not dilute or mix dornase alfa with other drugs in the nebulizer.

Inhalation devices require regular cleaning. Follow the manufacturer's written instructions for the care of the nebulizer.
