What is the maximum dose of ipratropium bromide via nebulizer?

• A. 0.5 mg/2.5 mL (Max 3 doses).
• B. 1.0 mg/2.5 mL (Max 3 doses).
• C. 0.25 mg/2.5 mL (Max 5 doses).
• D. 0.5 mg/1.25 mL (Max 3 doses).

Answer: (A)

Nebulized ipratropium bromide is dosed at 0.5 mg per inhalation in 2.5 mL of saline, with up to three doses given in a short period (often 20 minutes apart) for acute bronchospasm. This per-dose amount provides effective bronchodilation while limiting systemic anticholinergic side effects, and the cap of three doses prevents excessive exposure in a single treatment. That’s why the option listing 0.5 mg in 2.5 mL and a maximum of three doses matches standard practice. The other choices either change the per-dose amount or exceed the typical single-treatment dose limit, which is not in line with common guidelines.
