Nortriptyline: Your brand is changing from Norpress to Allegron (and supply issue)
The supplier of Norpress tablets is no longer supplying them to New Zealand. Allegron is replacing the Norpress brand.
5 September 2025 | Norpress 10 mg stock levels low
Due to delays at the factory, the supplier is running very low on stock of the Norpress 10 mg (Pharmacode: 2090678). The supplier aims to have stock arrive in New Zealand by the week beginning 8 September. It will take another 1 to 2 weeks to reach pharmacies. There is a small amount of stock in the supply chain.
New brand, same medicine
The supplier of Norpress has decided to stop supplying these tablets to New Zealand Aotearoa. We have found a replacement brand, Allegron.
Allegron has the same active ingredient in the same amount. It is designed to work in your body the same way. Allegron has been approved by Medsafe.
Medsafe is the government agency responsible for making sure medicines meet New Zealand standards of safety, quality and effectiveness.
What's changing?
While the active ingredient is the same, some of the other ingredients have changed. The tablets and packaging will also look different.
Keep taking your nortriptyline
Stopping this medicine suddenly may make you feel unwell. If you do want to stop taking it, seek the guidance of your doctor. You need to slowly reduce the dose of this medicine before stopping it completely.
Pharmacists
Thank you for supporting this brand change. Unfortunately, given the supplier's decision to withdraw this product from the New Zealand market, there is a short window of time to change people over to the new brand.
We have developed a flyer to support discussions with affected people.
