Information for people who take risperidone
To make sure you can continue to access funded treatment, Pharmac has funded different brands of risperidone, Risperidone Sandoz and Relonchem. You may have taken the Sandoz brand before, it was funded in 2024 and 2025.
Sandoz and Relonchem are different brands of the same medicine. The tablets contain the same active ingredients in the same quantities as your usual brand. The tablets and packaging will look different.
While these brands have not been reviewed by Medsafe for use in New Zealand, they are used in other countries. Your prescriber will discuss this with you before they prescribe the new brand.

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 when there is supply issue affecting the registered brand.
We know supplying an unapproved medicine is not ideal. In this case, however, this will allow people to continue to access an appropriate treatment.
We apologise for any inconvenience this causes.
