For Healthcare Professionals
Applies to dornase alfa: inhalation solution
Dornase alfa has been generally well tolerated. Dose ranging studies employing daily dosages as high as 40 mg revealed no significant adverse effects. The most common adverse reactions have been respiratory in nature and included pharyngitis (36% to 40% versus 33% with placebo, n=968), voice alteration or hoarseness (12% to 16% versus 7%), laryngitis (3% to 4% versus 1%), dyspnea and increase in cough. Rash has also occurred frequently (10% to 12% versus 7%).[Ref]
Many of these adverse reactions have been difficult to distinguish from symptoms of the underlying disease. Hoarseness and pharyngitis have been shown to be dose-related in one study. The hoarseness was transient and regressed after a 3 week period. Withdrawal rates in clinical trials have been similar between active and placebo groups.[Ref]
Cardiovascular side effects have included chest pain, which has been reported in 18% to 21% of patients receiving dornase alfa versus 16% with placebo.[Ref]
Ocular side effects have included conjunctivitis which has been reported in 4% to 5% of patients receiving dornase alfa versus 2% with placebo.[Ref]
Hypersensitivity side effects have included a small percentage of patients who developed serum antibodies to the drug, but no anaphylaxis or severe allergic reactions have been reported.
