Answer: Thank you for your question. Paramedic services are able to set service specific protocols for reusing or not reusing multi-dose medication vials. As with all medications proper rubber stopper cleaning procedures should be followed prior to delivering medication from a vial that has already had the cap removed. However multi-dose vials are falling out of favour in the patient safety literature. SWROBHP will follow up with services to discuss the advantages and disadvantages of multi dose vials.
