Myloc CR works the same way

Myloc CR contains the same active ingredient in the same quantities as the Betaloc CR brand. It will work in your body the same way. 

Medsafe has assessed the Myloc CR brand for safety, effectiveness, and quality. It meets the same standards as the Betaloc CR brand. It is approved for use in New Zealand.

Why is this happening?

Pharmac runs an annual tender on many of the medicines we fund. This tender gives suppliers an opportunity to offer already funded products for better, more competitive prices. The savings we make through the tender process frees up money so we can fund new treatments for people.

Following a recent tender, we made the decision to change from AstraZeneca's Betaloc CR brand to Viatris' Myloc CR brand.

This brand change is helping us fund more medicines for better health outcomes for all New Zealanders.
