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.

Understanding Cystic Fibrosis

You fight it every day—be sure to fight it in every way.

Cystic fibrosis (CF) is a complicated genetic disease that causes your body to produce extra-thick, sticky mucus. If you or your loved one is fighting this disease, they may require medicines as part of their treatment routine. Because not all medicines work the same or address the same symptoms, a combination of medications may be needed.

Pulmozyme is a commonly prescribed CF medicine that uniquely targets one of the causes for such mucus: extracellular DNA. In order to understand how Pulmozyme targets extracellular DNA, picture how a pair of scissors can be used to cut something into smaller pieces. Similarly, laboratory studies have shown that Pulmozyme cuts apart extracellular DNA by acting like an enzyme* found naturally in the body.

Your doctor and CF Care Team want you to have treatment that keeps you as healthy as possible. Being open about your questions or concerns can help you and your doctor make the right treatment decisions for your fight against CF. Continue reading through the next sections to find out more about how Pulmozyme may help you in your fight against CF.
