Rocuronium: Supply issue resolved

Some DHBs have advised PHARMAC and Medsafe about a potential lack of efficacy of batch 11331219A of the Hameln brand of rocuronium.

This brand of rocuronium is listed in the Pharmaceutical Schedule and has Hospital Supply Status (HSS) from August 2020 to 2022. Rocuronium is used in anaesthesia to help with intubation.  

Medsafe responsible for safety and efficacy

Medsafe are monitoring the situation and working with the supplier, Max Health.

What hospitals can do

Please report any and all events to Medsafe. They need detailed information to investigate any issue.

Hospitals are able to procure alternative rocuronium within the discretionary variance (DV) limit.

What PHARMAC is doing

PHARMAC is engaging with the supplier and Medsafe. We will communicate further as the situation evolves.

If the situation develops to the point that supply of the Hameln brand is interrupted, we understand there is sufficient stock of the DBL brand of rocuronium in New Zealand to maintain continuity of supply.
