Nortriptyline: Your brand is changing from Norpress to Allegron

Brand change Active

The supplier of Norpress tablets is no longer supplying them to New Zealand. Allegron is replacing the Norpress brand.

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. 

blister packs of nortriptyline. Norpress 10 mg are yellow, Allegron are white. Both Norpress and Allegron 25 mg are orange with a score mark .

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.

Affected products

Note the pack size for Allegron is smaller than Norpress.
