If a patient receives a prescription for ProAir HFA inhaler with the directions: “Take one to two puffs four to six times daily as needed for shortness of breath,” what is the days’ supply?
  1. 20 Days
  2. 30 Days
  3. 12 Days
  4. 16 Days
Explanation
Answer: D - With the listed directions, the patient would be receiving a 16-day supply. ProAir inhalers have 200 metered actuations. A technician must assume that the patient uses the maximum dosage; in this case it would be 12 metered actuations daily. 200 divided by 12 is 16.67; in cases where there are decimals, you should always round down.
