Short communication. The role of animal-sourced insulin in the treatment of type 1 diabetes and its availability.

As a result of a number of factors, the treatment of insulin-dependent diabetes has moved away from using insulin of beef or pork origin to using recombinant (biosynthetic) insulin preparations. However, some people with type 1 diabetes can manage their diabetes better using animal-sourced insulin. Despite dwindling options and decreased production, animal-sourced insulin (and pork insulin in particular) is still available on the Canadian market. This communication describes the actions taken by Health Canada with respect to the availability of animal insulin.
