What does Low, Mid, or High mean?
Each tier is named for the total you apply each day, across both sprays. It is not the amount in one spray, and it is not a spray count.
Neither the tier name nor the milligram figure on the label is a spray count — the label does not print one. Your dose is two sprays unless your provider tells you otherwise. If you are not sure which row is yours, message your care team before you start rather than guessing.
