A pharmacy technician is processing a prescription for albuterol sulfate (ProAir) 90 mcg per puff with instructions to "Take 1 puff po qid." What is the total daily dosage for this prescription?

To determine the total daily dosage for the prescription of albuterol sulfate (ProAir) 90 mcg per puff with the instructions to "Take 1 puff po qid," we need to break down the information provided.

The instruction "Take 1 puff po qid" indicates that the patient should take one puff by mouth four times a day (qid means "quater in die," which translates to four times a day). Each puff contains 90 mcg of albuterol sulfate.

To calculate the total daily dosage, we multiply the dosage per puff by the number of puffs taken throughout the day:

1 puff = 90 mcg

4 puffs (one for each of the four doses) = 90 mcg/puff x 4 puffs = 360 mcg.

Thus, the total daily dosage for this prescription is 360 mcg. This calculation confirms the provided answer as correct.
