Warfarin is a blood-thinning agent used to treat and prevent blood clots. Marevan is one of the two brands of warfarin currently funded in New Zealand, the other being Coumadin. The Marevan brand is used by the majority of patients.

The two brands of warfarin are not bioequivalent and careful clinical monitoring is required if switching between brands.  

The supplier of Marevan has provided notice to PHARMAC that it intends to increase the price of its product. This proposal would ensure that Marevan remains fully funded, reducing the likelihood that patients would need to switch brands in order to obtain a fully funded product, and it would ensure continuity of supply of Marevan.
