Zinc (Zincaps) 50 mg capsule: Supply issue

Supply issue Section 29A Active

There is a supply issue affecting Zincaps (Pharmacode: 258253).

19 March 2026 | Limited supply of alternative

There may be a short period from late March to early April where the supplier is out of Rugby Zinc capsules. More stock is on the way and is expected to arrive early April.

People may need to wait to have their prescription filled. We apologise for any disruption this causes.

NZ-registered Zincaps are expected to be available again later in April 2026. 

Affected product

There have been delays at the factory making Zincaps. The following product has been unavailable since mid-October 2025. 

  • Chemical: Zinc sulphate
  • Presentation: Cap 137.4 mg (50 mg elemental)
  • Brand: Zincaps
  • Pharmacode: 258253
  • Subsidy: $11.00
  • Measure / Qty: per 100

Pharmac is working with individual pharmacies to ensure supply is available for people with rare disorders.

Alternative products

Rugby Zinc

Rugby Zinc was funded from 1 January 2026. This is a product labelled for sale in the United States as a dietary supplement, rather than a prescription medicine. As such, there is no data sheet or product leaflet available. 

  • Chemical: Zinc sulfate heptahydrate
  • Presentation: cap 220 mg (equivalent to 50 mg elemental zinc) 
  • Pharmacode: 2719665
  • Subsidy: $29.14 
  • Measure/Qty: per 100
  • s29 and wastage claimable 

Key differences:

  • The Rugby capsule size is 220 mg compared to Zincaps 137.4 mg (zinc content is still the same = 50 mg).
  • Chemical name is zinc sulfate heptahydrate, instead of zinc sulphate monohydrate. 
  • Despite this product being labelled "dietary supplement", it is still a prescription medicine in New Zealand.

Zincaps S29

We listed this alternative from 1 October 2025. This product is exactly the same as the NZ-registered Zincaps but is packaged for Australia. The key difference is that the New Zealand label states that the medicine is prescription only.

  • Chemical: Zinc sulphate
  • Brand: Zincaps
  • Presentation: Cap 137.4 mg (50 mg elemental)  
  • Pharmacode: 2714019
  • Subsidy: $11.00
  • Measure / Qty: per 100
  • Unapproved medicine (Section 29) and wastage applies
The brand name, Zincaps, appears identically on both labels but there are other small differences between the 2 countries' labels..
Zincaps labels (the NZ label has "prescription only medicine")

Please keep Zincaps S29 and Rugby Zinc in dispensary

The alternative medicines do not have the ‘Prescription Medicine’ classification statement, because they are supplied for general sale in their home markets.

Please ensure that the Australian Zincaps and Rugby Zinc are kept in the dispensary and dispensed as a prescription-only medicine.

Prescribing and supplying an unapproved medicine

Section 29A of the Medicines Act 1981 allows for medicines that are not Medsafe approved to be prescribed and supplied to people. 

We know supplying an unapproved medicine. In this case, however, this will allow people to continue to access an appropriate treatment. 

We apologise for any inconvenience this causes. (external link)

Expected resupply April 2026

The supplier, Arrotex, expects the Medsafe-registered product will be available again in April 2026.
