The price of insulin varies depending on the type of insulin. Ordinary insulin is about 11-13 dollars per insulin; if it is short-acting insulin, such as Novolin 30R insulin, it is about 60-90 dollars per insulin. If it is a long-acting insulin, such as dextran insulin, and arginine, recombinant human insulin, it is about 200-300 yuan per insulin. If it is medium and long-acting insulin, it costs around 150 yuan. So, combine the insulin and its dosage for multiplication, and you can figure out how much it costs in 1 month.
