A dose refers to a specified amount of medication taken at one time. By contrast, the dosage is how to take the medication as prescribed: a specific amount, number, and frequency of doses over a specific period of time.
In other words, a dose is simply an amount of a medication you take at one specific time. The dosage is the dose, or amount of the drug, plus when and how often to take it. A dosage guides how you take or give the medication that’s been prescribed.
What is Xanax?
Xanax is a brand of alprazolam a benzodiazepine that works by enhancing the activity of certain neurotransmitters in the brain.

Generic blue, green, and yellow Xanax are considered to be just as safe and effective as the original drug but tend to cost less.
