Which Medication Dosage Form Needs a "Shake Well" Auxiliary Sticker?

Explanation:

The medication dosage form that requires a "shake well" auxiliary sticker is a suspension. A suspension is a type of pharmaceutical formulation comprised of finely divided solid particles dispersed throughout a liquid where the particles are not fully dissolved. Due to the nature of suspensions, the solid particles tend to settle at the bottom if the medication is left standing. Therefore, it is crucial to shake the suspension well before use to ensure a uniform distribution of the medication's active ingredients throughout the liquid. This allows the correct dosage to be administered each time the medication is used.

In contrast, solutions and elixirs do not require shaking as the active ingredients are completely dissolved, and syrups typically consist of a high concentration of sugar which helps dissolve and stabilize the active ingredients. As a result, syrups also do not usually need to be shaken before administration.
