Do you still have questions about Pulmozyme?


About Pulmozyme

Should I continue using Pulmozyme even when I can’t feel it?

One of the causes of thickened mucus in the lungs is extracellular DNA. Pulmozyme uniquely cuts apart extracellular DNA by acting like an enzyme naturally found in the lungs. Cutting up extracellular DNA can help thin mucus, making it easier to clear your lungs.

Pulmozyme has been shown to improve lung function even if you can’t feel it. It is important to take Pulmozyme as your doctor prescribed to make the mucus in your lungs thin and loose.

Why would my doctor still prescribe Pulmozyme if I am on a gene-specific CF treatment?

Every prescribed therapy plays a role to help you fight CF.

Pulmozyme is a mucolytic. It acts like a protein already in your body to cut apart the sticky mucus your lungs produce to make it thin and loose.

Gene-specific treatments, also called Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) modulators, were studied for use in patients with specific genetic mutations. Even though studies for these gene-specific treatments were not designed to look at the efficacy and safety of CFTR modulators in combination with existing treatments, patients in these studies stayed on their prescribed CF therapies (eg, Pulmozyme, tobramycin).

Please contact your doctor and/or cystic fibrosis (CF) Care Team to discuss your specific treatment plan and the distinct role each of your prescribed therapies plays.

Is Pulmozyme safe?

Pulmozyme was approved by the US Food and Drug Administration (FDA) in 1993, and was the first drug developed specifically for cystic fibrosis (CF).

Pulmozyme is to be used with other standard CF treatments and has demonstrated safety in children, adolescents, and adults. The efficacy of Pulmozyme has not been studied in patients less than five years of age.

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

What are the possible side effects of Pulmozyme?

You may feel more prepared if you talk to your doctor about what to expect before you begin Pulmozyme. Based on studies, patients taking Pulmozyme may experience 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. Mild to moderate hives and mild skin rash have been observed and have been short-lived. You should call your doctor if you experience any of these side effects or if any of these side effects are severe, get worse, or do not go away.

Is Pulmozyme right for me?

Pulmozyme is a commonly prescribed medicine that helps make mucus thin and loose in the lungs. In fact, 4 out of 5 patients take Pulmozyme.

Pulmozyme 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 greater than or equal to 40% of predicted, daily administration of Pulmozyme has also been shown to reduce the risk of respiratory tract infections requiring injectable antibiotics.

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

The Cystic Fibrosis Foundation recommends Pulmozyme for patients 6 years of age and older to:

  • Improve lung function, regardless of how sick one may be
  • Reduce the risk of exacerbations or lung infections

In a study of patients 5 years and older with mild to moderate disease who took Pulmozyme daily, patients showed fewer lung infections and an improvement in lung function compared with those not taking Pulmozyme.

Talk to your doctor to decide if Pulmozyme is right for you.

A prospective, randomized, placebo-controlled study evaluated the effects of once-daily and twice-daily administration of Pulmozyme on exacerbations of respiratory symptoms requiring IV antibiotics and on
pulmonary function. A total of 968 adults and children five years of age or older with CF were treated for
24 weeks as outpatients.

Which dose of Pulmozyme is right for me?

The recommended dose for most CF patients is Pulmozyme 2.5 mg once daily.

Some patients over 21 may benefit from twice-daily treatment. You should ask your doctor whether prescribing Pulmozyme 2.5 mg twice daily may be right for you.

Taking Pulmozyme

Why is Pulmozyme an important part of my cystic fibrosis treatment regimen?

Treating cystic fibrosis (CF) is complicated so it is important to take all your treatments as prescribed by your doctor. Pulmozyme works uniquely among medicines to help thin and loosen mucus. Your doctor may prescribe other medicines to take in addition to Pulmozyme. These other medicines may include: 

  • Bronchodilators help open airways
  • Hydrators help increase moisture in thick mucus 
  • Airway clearance techniques help physically loosen and move mucus out of the way
  • Antibiotics help prevent and treat infections 
  • Gene-specific treatments, also known as Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) modulators, help keep a balance of salt and water in the lungs

What nebulizers can I use to take Pulmozyme?

The FDA has approved specific nebulizers/compressors to be used with Pulmozyme.

One nebulizer system is FDA-approved:

  • eRapid® (PARI) Nebulizer System

The following nebulizers and compressors have been approved for use with Pulmozyme:

  • Hudson T Up-draft II® with Pulmo-Aide®
  • Marquest Acorn II® with Pulmo-Aide®
  • PARI LC® PLUS with PARI PRONEB®
  • PARI BABY with PARI PRONEB®
  • Durable Sidestream® with MOBILAIRE
  • Durable Sidestream® with Porta-Neb®

Please contact your doctor and/or cystic fibrosis (CF) Care Team for more information about nebulizers and compressors, and for guidance in choosing products that are right for you.

How do you use the Pulmozyme ampule?

Pulmozyme comes in sterile, single-use ampules that should be used completely. Because Pulmozyme has no preservatives, the entire contents must be used or discarded.

It is important to store ampules of Pulmozyme in their protective foil pouch under refrigeration and protected from light. Refrigerate ampules during transport and do not expose to room temperatures for a total time of 24 hours.

Each ampule should be squeezed prior to use in order to check for leaks. Discard ampules if the solution is cloudy or discolored. Once opened, the entire contents of the ampule must be used or discarded.

How can I fit my Pulmozyme treatment into my daily routine?

Finding the time and place to take your treatments, like Pulmozyme, isn’t always easy. No one is perfect. But having a routine that fits your lifestyle can help you stay in control and assist in your fight against cystic fibrosis (CF).

Does Pulmozyme expire?

There are expiration dates stamped on each ampule. It is important to follow the stamped date and discard any ampules that expire.

How should I store Pulmozyme?

Each sterile, single-use ampule of Pulmozyme (2.5 mg) is packaged in a protective foil pouch. The ampules should be left in their foil package and stored in the refrigerator. They should also be kept away from strong light.

Understanding cystic fibrosis

What is cystic fibrosis?

Cystic fibrosis (CF) is a genetic condition, which means that it is something you are born with. CF is known to cause your lungs to produce extra-thick, sticky mucus. This mucus builds up and clogs your airways.

What makes healthy lungs "healthy"?

The lungs naturally produce a thin layer of mucus that helps protect the airways from dangerous bacteria that can cause infections.

How are lungs affected by CF different?

For people living with CF, the mucus in the lungs is thicker than normal, and becomes a source of inflammation and infection that can lead to lung damage.

Indication and Usage

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.

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.
