1.1.1 Multi-dose vial: It is a bottle of liquid medication that contains more
than one dose of medication and is recognized by its FDA-approved label.
Healthcare providers use multi-dose vials to deliver a variety of medications
and vaccines. If handled safely, they can be accessed for more than one
patient. Healthcare providers should always use a new needle and syringe when
accessing the contents of a multi-dose vial. Reuse of needles or syringes can
contaminate medicine with germs, which can spread to others. 1.1.2 Single-dose vial: It is a bottle of liquid medication healthcare
providers give to a patient using a needle and syringe. A single-dose vial is
approved for use on a single patient for a single procedure or injection.
