When a biological has been on the market for several years, other manufacturers are allowed to make it. This drug from another manufacturer is called a biosimilar.

Bioligicals are often very expensive. Therefore, many hospitals choose to switch to biosimilars. These are usually cheaper. Both biologicals and biosimilars are made from a living organism. The action is the same, but the composition is not quite the same.

Because biologicals and biosimilars can differ in composition, hospitals are required to inform patients about the switch. This Divi can be used to inform patients about the change.
