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
Metered-dose inhaler (MDI): 2 inhalations (34 mcg) 4 times daily; maximum dose: 12 inhalations (204 mcg)/day
Nebulization solution: 0.5 mg (500 mcg, one unit-dose vial) every 6 to 8 hours
Acute asthma (exacerbations) (off-label use): Moderate to severe exacerbations:
Inhalation: Note: Should be given in combination with a short-acting beta-adrenergic agonist.
MDI: 8 inhalations (136 mcg) every 20 minutes as needed for up to 3 hours (NAEPP 2007)
Nebulization solution: 0.5 mg (500 mcg, one unit-dose vial) every 20 minutes for 3 doses, then as needed (NAEPP 2007)
Refer to adult dosing.
Asthma, acute exacerbation: Limited data available (GINA 2018; NAEPP 2007): Note: For moderate to severe exacerbations, ipratropium may be considered if poor response to initial short-acting beta-2 agonist (SABA) therapy during initial management in an acute care setting (eg, emergency department). Ipratropium has not been shown to provide further benefit (eg, after first 24 hours) once the patient is hospitalized (GINA 2018; Vézina 2014):
Nebulization: 0.25 to 0.5 mg (250 to 500 mcg) every 20 minutes for 1 hour (ie, 3 doses), then as needed; in trials, the usual reported dose is 0.25 mg (250 mcg) and reported interval range is every 1 to 8 hours typically with an increasing dosing interval as patient improves; some trials continued combination SABA/ipratropium therapy for duration of hospitalization (up to 49 hours) although trials have not demonstrated additional benefit with extended use (Vézina 2014)
Metered-dose inhaler: 4 to 8 puffs every 20 minutes as needed for up to 3 hours
Nebulization: 0.5 mg (500 mcg) every 20 minutes for 3 doses, then as needed
Metered-dose inhaler: 8 puffs every 20 minutes as needed for up to 3 hours
Asthma, maintenance (nonacute): Limited data available: Note: Evidence is lacking that ipratropium provides added benefit to beta-2 agonists in long-term control asthma therapy (GINA 2018; NAEPP 2007):
Children <12 years:
Nebulization: 0.25 to 0.5 mg (250 to 500 mcg) every 6 to 8 hours
Metered-dose inhaler: 1 to 2 inhalations every 6 hours; not to exceed 12 inhalations/day
Children ≥12 years and Adolescents:
Nebulization: 0.25 to 0.5 mg (250 to 500 mcg) every 6 hours
Metered-dose inhaler: 2 to 3 inhalations every 6 hours; maximum daily dose: 12 inhalations/day
Bronchospasm associated with chronic pulmonary conditions: Children ≥12 years and Adolescents: Nebulization: 0.5 mg (500 mcg, one unit-dose vial) 3 to 4 times daily with doses 6 to 8 hours apart
Bronchospasm, wheezing: Limited data available; efficacy results variable: Infants: Nebulization: 0.125 to 0.25 mg (125 to 250 mcg) every 4 hours has been found helpful in some infants with chronic or recurrent wheezing, and some patients with bronchiolitis; however, most bronchiolitis data suggests ipratropium is not effective (Hodges 1981; Prendiville 1987; Schuh 1992; Stokes 1983; Wang 1992).
For oral inhalation; avoid spraying in eyes.
Metered-dose inhaler: Prior to initial use, prime inhaler by releasing 2 test sprays into the air; inhaler does not require shaking. If the inhaler has not been used for >3 days, reprime. Wash mouthpiece once a week for 30 seconds in warm water only and let air dry. Discard inhaler once dose indicator displays “0.”
Nebulization solution: Remove unit dose vial from foil pouch and squeeze contents into nebulizer reservoir; connect nebulizer to compressor. Breathe deeply and evenly until all medication has been inhaled; inhalation time is about 5 to 15 minutes. Clean nebulizer after use.
Metered-dose inhaler: Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Exposure to temperatures >48°C (120°F) may cause bursting. Do not puncture inhaler, throw into a fire or incinerator, or use or store near heat or open flame.

Concerns related to adverse effects:
• Bronchospasm: Paradoxical bronchospasm that may be life-threatening and may occur with use of inhaled bronchodilating agents; this should be distinguished from inadequate response. If paradoxical bronchospasm occurs, discontinue ipratropium and institute alternative therapy.
• CNS effects: May cause dizziness and blurred vision; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).
• Hypersensitivity reactions: Hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm, oropharyngeal edema), including anaphylaxis, have been reported. Discontinue therapy immediately if patient develops an allergic reaction.
• Glaucoma: Use with caution in patients with narrow-angle glaucoma; may increase intraocular pressure.
• Prostatic hyperplasia/bladder neck obstruction: Use with caution in patients with prostatic hyperplasia or bladder neck obstruction; may cause urinary retention.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions for more detailed information.
• Appropriate use: Not indicated for the initial treatment of acute episodes of bronchospasm where rescue therapy is required for rapid response. Only use 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; signs/symptoms of glaucoma; hypersensitivity reactions; urinary retention
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies.
• 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, dry mouth, flu-like symptoms, nasal irritation, pharyngitis, or rhinitis. Have patient report immediately to prescriber signs of a urinary tract infection (hematuria, burning or painful urination, polyuria, fever, lower abdominal pain, or pelvic pain), vision changes, eye pain, severe eye irritation, visual halos or bright colors around lights, red eyes, difficulty urinating, urinary retention, polyuria, severe dizziness, passing out, tachycardia, abnormal heartbeat, mouth sores, mouth irritation, 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.
