Your patient may be eligible for the Pulmozyme Co-pay Assistance Program.

Co-pay Card Assistance

The Pulmozyme Co-pay Program works to help eligible, commercially insured patients pay as little as $30 for a 30-day supply of Pulmozyme. The Pulmozyme Co-pay Program covers any additional out-of-pocket costs for Pulmozyme, after you pay $30 for each 30-day supply, up to $10,000 per calendar year, for most privately insured patients.

  • The remainder of the co-pay or co-insurance is covered up to $10,000 per calendar year.
  • There is no income requirement.

Patients may be eligible if they:

  • Are taking Pulmozyme for an FDA-approved use
  • Are 18 years of age or older or have a Legally Authorized Person over the age of 18 to manage the program
  • Have commercial (private or non-governmental) insurance. This includes plans available through state and federal health insurance exchanges
  • Live and receive treatment in the United States or U.S. Territories
  • Are not receiving assistance through the Genentech Patient Foundation or any other charitable organization for the same expenses covered by the program
  • Do not use a state or federal healthcare plan to pay for your medication. This includes, but is not limited to, Medicare, Medicaid and TRICARE

The Co-pay Program (“Program”) is valid ONLY for patients with commercial (private or non-governmental) insurance who have a valid prescription for a Food and Drug Administration (FDA)-approved indication of a Genentech medicine. The Program is not available to patients whose prescriptions are reimbursed under any federal, state, or government-funded insurance programs (included but not limited to Medicare, Medicare Advantage, Medigap, Medicaid, TRICARE, Department of Defense, or Veterans Affairs Programs) or where prohibited by law or by the patient’s health insurance provider. If at any time a patient begins receiving prescription drug coverage under any such federal, state or government-funded healthcare programs, the patient will no longer be eligible for the Program.

Under the Program, the patient may be required to pay a co-pay. The final amount owed by a patient may be as little as $0 for the Genentech medicine (see Program specific details available at the Program website). The total patient out-of-pocket cost is dependent on the patient’s health insurance plan. The Program assists with the cost of the Genentech medicine only. It does not assist with the cost of other medicines, procedures or office visit fees. After reaching the maximum annual Program benefit amount, the patient will be responsible for all remaining out-of-pocket expenses. The Program benefit amount cannot exceed the patient’s out-of-pocket expenses for the Genentech medicine.

All participants are responsible for reporting the receipt of all Program benefits as required by any insurer or by law. The Program is only valid in the United States and U.S. Territories, is void where prohibited by law and shall follow state restrictions in relation to AB-rated generic equivalents (e.g., MA, CA) where applicable. No party may seek reimbursement for all or any part of the benefit received through the Program. The value of the Program is intended exclusively for the benefit of the patient. The funds made available through the Program may only be used to reduce the out-of-pocket costs for the patient enrolled in the Program. The Program is not intended for the benefit of third parties, including without limitation third party payers, pharmacy benefit managers, or their agents. If Genentech determines that a third party has implemented a program that adjusts patient cost-sharing obligations based on the availability of support under the Program and/or excludes the assistance provided under the Program from counting towards the patient’s deductible or out-of-pocket cost limitations, Genentech may impose a per fill cap on the cost-sharing assistance available under the Program. Submission of true and accurate information is a requirement for eligibility and Genentech reserves the right to disqualify patients who do not comply with Genentech Program Terms and Conditions. Genentech reserves the right to rescind, revoke or amend the Program without notice at any time.

Additional terms and conditions apply. Please visit the Co-pay Program website for the full list of Terms and Conditions.

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%).
