This guide is designed to give you an idea of how your insulin works as well as specifying both the brand and generic name of the most widely used insulins. In the instance that you cannot get hold of your regular brand of insulin, you can consult this chart to identify an appropriate substitute. Of course you should always consult a doctor before switching medication.
The brand name of your insulin may vary across countries, for example, Novolog is called Novorapid in the UK, but they are exactly the same thing: insulin aspart. There may be other variations in brand names, so make sure to give the doctor the generic name of your insulin as detailed in the table below.
