Off Label Uses
Acute asthma (exacerbations)
Based on the National Heart, Lung, and Blood Institute (NHLBI)/National Asthma Education and Prevention Program (NAEPP) guidelines, the use of ipratropium in combination with a short-acting beta-agonist (SABA), such as albuterol, is an effective and recommended treatment in the management of patients with asthma exacerbation. Controlled trials and a meta-analysis have demonstrated that the addition of ipratropium to SABA therapy in the management of moderate to severe acute asthma exacerbations has been associated with a decreased risk of hospitalization and an improvement in lung function.
Hypersensitivity to ipratropium, atropine (and its derivatives), or any component of the formulation

Concerns related to adverse effects:
• Bronchospasm: Rarely, paradoxical bronchospasm may occur with use of inhaled bronchodilating agents; this should be distinguished from inadequate response.
• Hypersensitivity reactions: Immediate hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm) have been reported.
• Glaucoma: Use with caution in patients with narrow-angle glaucoma.
• Myasthenia gravis: Use with caution in patients with myasthenia gravis.
• Prostatic hyperplasia/bladder neck obstruction: Use with caution in patients with prostatic hyperplasia or bladder neck obstruction.
• Appropriate use: Inhalation/nebulizer not indicated for the initial treatment of acute episodes of bronchospasm where rescue therapy is required for rapid response. Should only be used in acute exacerbations of asthma in conjunction with short-acting beta-adrenergic agonists for acute episodes (NAEPP 2007).
FEV1, peak flow, and/or other pulmonary function tests; shortness of breath
Pregnancy Risk Factor
Teratogenic effects were not observed in animal studies. Inhaled ipratropium is recommended for use as additional therapy for pregnant women with severe asthma exacerbations.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience back pain, headache, flu-like symptoms, nasal irritation, pharyngitis, or rhinitis. Have patient report immediately to prescriber vision changes, eye pain, severe eye irritation, urinary retention, painful urination, polyuria, severe dizziness, passing out, tachycardia, arrhythmia, mouth sores, difficulty breathing, wheezing, or cough (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
