A drug with a short half-life is typically given how often?

Explanation:
When a drug is cleared quickly, its concentrations fall fast, so to keep the medicine working consistently you need to dose it several times a day at regular intervals. This maintains drug levels within the therapeutic window and avoids periods of subtherapeutic exposure. Dosing only once daily or weekly would let levels drop too low before the next dose, and taking it only when the patient requests it leads to unpredictable exposure.
