Information for prescribers

We asked that you do not start new patients on amiloride oral liquid. You may like to consider amiloride tablets (funded from 1 December) or an alternative potassium-sparing diuretic(external link) for your patients who are taking amiloride oral liquid.

Information for community pharmacists

We arranged for hospital pharmacies to supply community with the oral liquid as a stop gap effort to ensure people could continue to access this treatment. 

We then listed amiloride tablets in the Community Schedule from 1 December for those who can take tablets.

For hospital pharmacists

The Schedule Rules say that Health NZ Hospitals may give any hospital pharmaceutical to a patient for use in the community, provided that:

• the quantity dispensed at any one time does not exceed the amount sufficient for up to 30 days’ treatment, unless:
  • it would be inappropriate to provide less than the amount in an original pack, or
  • the relevant Health NZ Hospital has a policy covering dispensing for discharge and the quantity dispensed is in accordance with that policy, and
• the Hospital Pharmaceutical is supplied consistent with any applicable restrictions in Section H of the Schedule (includes Indication Restrictions, Local Restrictions and Prescriber Restrictions).

We appreciate your continued support in ensuring a patient level impact is avoided.

Alternative tablets listed 

From 1 December 2024, we listed two brands of amiloride 5 mg tablets for people who can swallow a tablet:

Wastage is claimable. Neither product is Medsafe registered. As such they will have to be prescribed and dispensed in line with the Medicines Act.

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.
