Symptom narrative

Powder portion with a different diluent; Powder portion with a different diluent; This non-serious case was reported by a pharmacist via call center representative and described the occurrence of wrong solution used in drug reconstitution in a patient who received Men ACWY-CRM NVS (Menveo) (batch number AMVB043A, expiry date 30-JUL-2025) for prophylaxis. On 15-JAN-2025, the patient received Menveo. On an unknown date, an unknown time after receiving Menveo, the patient experienced wrong solution used in drug reconstitution (Verbatim: Powder portion with a different diluent) and inappropriate dose of vaccine administered (Verbatim: Powder portion with a different diluent). The outcome of the wrong solution used in drug reconstitution and inappropriate dose of vaccine administered were unknown. Additional Information: GSK Receipt Date: 30-JAN-2025 Pharmacist might have mixed the powder with sterile water for injection instead of the diluent that comes with the product, which led to Wrong solution used in drug reconstitution and Inappropriate dose of vaccine administered. So just trying to see if they had any information, if they just gave the second bottle on its own, or if they needed to re-dose the whole thing. During the call, the healthcare professional mentioned that in their inventory they only had the liquid portion for the Menveo, so they thought that the powder portion might have been administered with sterile water for injection.
