Frequently used with the preposition 'of' to name the medicine ('dosage of antibiotics'), and 'for' to name the patient group ('dosage for children'). Contrast with dose: a dose is a single measured amount taken at one time (e.g., 'one 500 mg dose'), while dosage refers to the entire schedule — both the amount and the frequency.
