Sumatriptan: Your brand is changing to Clustran
Clustran brand sumatriptan will be funded from 1 November 2023. Imigran brand will stop being funded on 1 May 2024.
27 October 2023 update
Clustran brand sumatriptan
From 1 November 2023, Pharmac will fund the Clustran brand of sumatriptan. This is a change from the currently funded Imigran brand.
You may recognise Clustran. It was the funded brand from January 2016 and September 2020.
The Imigran pen will remain funded until 1 May 2024. Your pharmacist will change you to the Clustran brand sometime between 1 November 2023 and 1 May 2024.
How are they different?
The key change is that Clustran comes in pre-filled pens. The pens are single use. Imigran brand had a reusable pen.
Both brands have the same active ingredient in the same amount. They work in your body the same way.
Consumer resources are available on Healthify.nz(external link), including videos in English and Māori on how to use the pen. Healthify is an independent source of plain language health information for Aotearoa.

Why is this changing
Pharmac runs a regular tender process to make sure we're getting the best medicines at the best prices, while staying within the government's Combined Pharmaceutical Budget. As part of this process, we have signed an agreement with Douglas, the supplier of Clustran. They will be the principal supplier of injectible sumatriptan from 1 November 2023.
Pharmac uses the tender process to reduce the cost of already funded medicines. This frees up the government's medicine budget to fund more medicines for more people.
