Pulmozyme® (dornase alfa) is indicated for daily administration along with standard therapies for the management of cystic fibrosis (CF) patients to improve pulmonary function.

In CF patients with an FVC ≥ 40% of predicted, daily administration of Pulmozyme has also been shown to reduce the risk of respiratory tract infections requiring injectable antibiotics.

Important Safety Information

Pulmozyme should not be used in patients who are allergic to any of its ingredients.

Patients may experience the following when using Pulmozyme: change in or loss of their voice, discomfort in the throat, rash, chest pain, red watery eyes, runny nose, lowering of lung function, fever, indigestion and shortness of breath. There have been no reports of severe allergic reactions caused by the administration of Pulmozyme. Mild to moderate hives and mild skin rash have been observed and have been short-lived.

You are encouraged to report side effects to Genentech and the FDA. You may report side effects to the FDA at 1-800-FDA-1088 or You may also report side effects to Genentech at 1-888-835-2555.

For further information, please see the Pulmozyme full Prescribing Information.

Pediatric Use

The safety and effectiveness of Pulmozyme have been established in patients 5 years of age and older. While clinical trial data are limited in patients younger than 5 years of age, the use of PULMOZYME should be considered for pediatric CF patients who may experience potential benefit in lung function or who may be at risk of respiratory tract infection.

The safety of Pulmozyme given by daily inhalation for 2 weeks has been studied using 98 CF patients with 65 of them aged 3 months to <5 years (younger group) and 33 aged 5 years to <10 years (older group). The PARI BABY™ reusable nebulizer (which uses a face mask instead of a mouthpiece) was used in patients who were unable to show that they could breathe in or out using their mouth throughout the entire treatment period. Overall, the kind of side effects observed in children was similar to those seen in larger trials in older patients.

Pulmozyme Access Solutions®

Nebulizers and compressors

You need a nebulizer and a compressor to take Pulmozyme. However, not all nebulizers and compressors are the same. Your doctor or healthcare team can help you make the selection that best fits your needs. Here are some things you may want to talk about:

  • Is it FDA approved? Did you know that the FDA approves the use of certain nebulizers and compressors for certain medicines? See a list of FDA-approved nebulizers and compressors below.
  • What is your lifestyle like? This is an investment in your health, so you will want it to fit into your life. Consider what conveniences you need. For example, nebulizers/compressors may have different delivery times and cleaning instructions.
  • Will a child use it? Certain nebulizers are designed especially for younger children and have features such as a mask instead of a mouthpiece.
  • How much will it cost? Costs, out-of-pocket expenses, and insurance coverage can vary. If you need help to better understand your insurance coverage, Pulmozyme Access Solutions® may be able to help.
    A new nebulizer, the eRapid® (PARI) Nebulizer System, has been approved by the FDA for use with Pulmozyme. Payer coverage and patient out-of-pocket costs vary and may change over time. Patients should consult with the specialty pharmacies that distribute eRapid, who will help navigate insurance coverage and possible reimbursement challenges.
