Alternative product

Teva secured 1,000 packs of an alternative product, Naltrexone AOP (Pharmacode 2664941). The alternative was not Medsafe approved and had to be prescribed and dispensed in line with section 29 of the Medicines Act. 

The alternative was listed on the Pharmaceutical Schedule from 1 October 2023. The pack size was 28 tabs per pack and the price is equivalent to the Naltraccord brand (pro rata).

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.
