Important Safety Information

Indication and Usage

Pulmozyme (dornase alfa) is indicated for daily administration in conjunction 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 parenteral antibiotics.

Pulmozyme is contraindicated in patients with known hypersensitivity to dornase alfa, Chinese Hamster Ovary cell products, or any component of the product.

The most common adverse reactions associated with the use of Pulmozyme include: voice alteration, pharyngitis, rash, laryngitis, chest pain, conjunctivitis, rhinitis, decrease in FVC of ≥ 10%, fever, dyspepsia, and dyspnea. There have been no reports of anaphylaxis attributed to the administration of Pulmozyme. Mild to moderate urticaria and mild skin rash have been observed and have been transient.

Pediatric Use

The safety and effectiveness of Pulmozyme in conjunction with standard therapies for cystic fibrosis have been established in pediatric patients. Use of Pulmozyme in pediatric patients is supported by evidence in the following age groups:

  • Patients 5 to 17 years of age: A randomized, placebo-controlled trial of 303 of clinically stable cystic fibrosis patients 5 to 17 years of age who received Pulmozyme.
  • Patients less than 5 years: Extrapolation of efficacy data in patients 5 years of age and older with additional safety data in 65 pediatric patients aged 3 months to less than 5 years who received Pulmozyme 2.5 mg daily by inhalation for 2 weeks.

The safety of Pulmozyme, 2.5 mg by inhalation, was studied with 2 weeks of daily administration in 98 pediatric patients with cystic fibrosis 3 months to 10 years of age (65 aged 3 months to < 5 years, 33 aged 5 to ≤ 10 years). The PARI BABYTM reusable nebulizer (which uses a facemask instead of a mouthpiece) was utilized in patients unable to demonstrate the ability to inhale or exhale orally throughout the entire treatment period (54/65, 83% of the younger; and 2/33, 6% of the older patients). Overall, the nature of adverse reactions was similar to that seen in the placebo-controlled trials in older patients. The number of patients reporting cough was higher in the younger age group as compared to the older age group (29/65, 45%; compared to 10/33, 30%) as was the number reporting moderate to severe cough (24/65, 37%; compared to 6/33, 18%). The number of patients reporting rhinitis was higher in the younger age group as compared to the older age group (23/65, 35%; compared to 9/33, 27%) as was the number reporting rash (4/65, 6% as compared to 0/33, 0%).
