What do you call the container that holds one-time use medication?

The container that holds one-time use medication is called an ampule. Ampules are sealed glass or plastic containers designed to hold a single dose of a medication. They are typically used for medications that are potent and need to be protected from contamination or degradation by light or air, ensuring the integrity and effectiveness of the drug until it is needed.

Upon breaking the neck of the ampule, the medication can be drawn out using a syringe for administration. The design of an ampule makes it ideal for such applications, as it provides a closed environment that can be easily opened to access the medication.

In contrast, a vial is usually a multi-dose container that can hold multiple doses of a medication, making it less suitable for one-time-use scenarios. Syringes are instruments used to inject the medication but do not serve as a container, and a hub is a component that connects different pieces of a syringe or other medical devices but does not hold medication on its own.
