What is a single-dose vial?

A single-dose vial refers to a container of medication that is specifically designed for one-time use. This means that once the vial is opened and accessed, the entire contents are intended to be used immediately, without the possibility of obtaining additional doses from that same vial.

The key characteristic of a single-dose vial is that it typically does not contain any preservatives, which would allow for extended storage after opening. This absence of preservatives highlights its purpose for immediate use, ensuring that the medication remains sterile and effective at the time of administration. It is crucial in settings such as hospitals or clinics where sterility and dosage accuracy are vital to patient safety.

In contrast, multi-use vials are intended for multiple administrations and contain preservatives to prolong their shelf life once opened. Extended shelf life or preservation features are qualities of multi-dose vials, which are not applicable to single-dose vials.
