Ipratropium Inhaler Dosing for Adults

Standard Maintenance Dosing

• The American Thoracic Society recommends a standard dose of 2 puffs (18 mcg per puff = 36 mcg total) four times daily for MDI formulation 1

Acute Exacerbation Dosing

• For acute exacerbations of asthma or COPD, the American College of Allergy, Asthma, and Immunology recommends 8 puffs (144 mcg total) every 20 minutes as needed for up to 3 hours 2, 1
• The American College of Allergy, Asthma, and Immunology also recommends administering 0.5 mg every 20 minutes for 3 doses, then as needed for nebulizer administration 2, 1

Combination Therapy with Albuterol

• The American College of Allergy, Asthma, and Immunology recommends a combination solution of 3 mL (containing 0.5 mg ipratropium + 2.5 mg albuterol) every 20 minutes for 3 doses for acute exacerbations 2, 1

Clinical Context and Important Caveats

• The American College of Allergy, Asthma, and Immunology advises that ipratropium should NOT be used as first-line therapy for acute asthma exacerbations, but rather added to SABA therapy for severe cases 2, 1
• The American College of Chest Physicians recommends proper inhaler technique to maximize drug delivery to the lungs 1
• For nebulizer use, the American Association for Respiratory Care recommends ensuring adequate flow rate (6-8 L/min with oxygen-driven nebulizer) and diluting to a minimum of 3 mL for optimal nebulization 3
