What unit is used to describe the typical albuterol MDI dose?

• A. Milligrams
• B. Inhalations
• C. Doses
• D. Puffs

Answer: (D)

The main idea is that inhaled medications from a metered-dose inhaler are described by how many times you actuate the device. Each spray delivers a fixed amount, so the standard way to express a typical albuterol MDI dose is in puffs (or inhalations). For example, a common rescue dose is 2 puffs every 4–6 hours as needed. Each puff contains about 90 micrograms of albuterol, but you’ll most often see the instruction given as a number of puffs rather than milligrams or simply “a dose,” since the device delivers fixed increments with each actuation.
