Alternative product

We listed an alternative product from 1 May 2025, in case the supply situation worsened. It is not Medsafe registered.

• Brand name: Gentamicin Hikma
• Strength and presentation: Inj 10 mg per ml, 2 ml ampoule (i.e. 20 mg/2 ml per amp), 10 pack. This is a different ampoule size and pack size to the registered product, which is 1 ml ampoule x 5 pack.
• Packaging: dual language English and French.
• Pharmacode: 2705435
• Price: $190.00 per pack

We understand that the Gentimicin Hikma brand is not suitable for use with a nebuliser, due to the presence of sodium metabisulphite. If necessary, please reserve stock of the registered DBL Gentamicin product for people that cannot use the alternative brand until supply is restored. We are working on this urgently.

Prescribing and supplying an unapproved medicine

Section 29 of the Medicines Act 1981 allows for medicines that are not Medsafe approved to be prescribed and supplied to people. The medicine must be prescribed by someone registered with the Medical Council of New Zealand – such as, a doctor. 

We know supplying a medicine under section 29 is not ideal. In this case, however, this will allow patients to be able to access an appropriate treatment. 

We apologise for any inconvenience this causes.
