Alternative listed 1 July 2024

An alternative was sourced from the UK which is identical to the registered medicine. It is produced in the same facilities with the same manufacturing process as Allmercap. The only difference is the labelling and oral dosing syringes supplied with the product. However it is not Medsafe approved and as such will need to be prescribed and supplied in line with section 29 of the Medicines Act.

  • Brand name: Xaluprine
  • Pharmacode: 2682257

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.
