Homonym: Refill (Recharge)
A "refill" refers to the act of replenishing a container or supply that has been depleted. This can apply to various items, such as drinks, medications, or ink cartridges. For example, when you finish a bottle of water, you might refill it at a water fountain or tap.
In the context of prescriptions, a refill allows patients to obtain additional doses of their medication without needing a new prescription from their doctor. This process is often managed through pharmacies, which keep track of the number of refills allowed for each prescription based on the doctor's instructions.
