What are the main safety risks of Pulmozyme (dornase alfa)?
Pulmozyme (dornase alfa) is generally well tolerated, but safety monitoring matters most for lung-related adverse events and rare hypersensitivity reactions.
Commonly reported side effects include voice changes (hoarseness), sore throat, and cough. Patients may also experience gastrointestinal symptoms such as nausea. Other reported effects include rash and fever.
Serious but uncommon safety concerns include severe allergic reactions (including anaphylaxis) and other hypersensitivity reactions. If symptoms of allergy occur, dosing should be stopped and urgent medical care sought.
How do Pulmozyme side effects compare with placebo or other CF inhaled therapies?
In clinical experience, many adverse events associated with Pulmozyme are mild and reversible after stopping or adjusting therapy, with cough and throat/voice symptoms being among the more noticeable issues. Compared with many symptomatic inhaled treatments, Pulmozyme’s safety profile is often dominated by upper airway irritation rather than systemic toxicity.
If you are comparing options, the key practical question is whether your current regimen already includes therapies that can also cause cough or bronchospasm, because those effects can overlap and make side effects harder to attribute.
What happens if Pulmozyme makes your cough or breathing worse?
If Pulmozyme triggers increased cough, wheezing, or shortness of breath, clinicians typically assess:
- Whether the patient is also dealing with infection or disease flare.
- Whether there is hypersensitivity (especially if there is rash, swelling, or breathing difficulty soon after dosing).
- Whether dosing technique or timing with other inhaled medications might be contributing to throat/airway irritation.
Do not keep dosing through severe breathing symptoms. Urgent care is appropriate for severe shortness of breath, lip/tongue swelling, or signs of anaphylaxis.
Who should be extra careful when using Pulmozyme?
Extra caution is warranted for patients with a history of significant hypersensitivity reactions to dornase alfa or its components. Anyone with worsening respiratory symptoms after starting or changing the dose should be reassessed by a clinician to rule out infection, progression of lung disease, or an adverse reaction.
Are there long-term safety concerns with chronic Pulmozyme use?
Pulmozyme is used chronically in eligible patients with conditions such as cystic fibrosis to improve lung function by reducing airway mucus viscosity. Long-term safety concerns are not dominated by cumulative organ toxicity in the way some systemic therapies can be. The most persistent tolerability issues tend to involve local respiratory or throat effects, while serious reactions are uncommon.
Pregnancy/breastfeeding safety: what’s known?
Safety during pregnancy and breastfeeding is assessed case-by-case based on severity of lung disease and the availability of alternative treatments. If you are pregnant, planning pregnancy, or breastfeeding, your prescriber will weigh expected benefits for lung health against the need for individualized risk counseling.
Where can I find official prescribing information and safety details?
For the most accurate safety information (including contraindications, warnings, and complete adverse-event tables), refer to the official prescribing information.

What do patients usually ask about day-to-day safety?
Patients commonly ask whether voice changes and throat irritation are expected, whether timing with other inhaled drugs helps, and what symptoms mean they should call a clinician. Mild hoarseness and throat discomfort can occur, but worsening breathing, rash, facial swelling, or allergy symptoms require prompt medical attention.
