What is the difference between Humulin N and humalog R?
In the words of your question, you illustrate the problem with the names of different types of insulin. There is no such thing as “Humalog R,” It’s not your fault; the names are confusing. Humulin is a brand of insulin. It does not tell you the type of insulin. It tells you that the insulin was made by Eli Lilly and Company. Humalog is rapid-acting insulin made by the same company. Similarly, Novolin is the brand name used for insulin made by Novo Nordisk. Novolog is the rapid-acting insulin made by this company. There is one other rapid-acting insulin – Apidra. Fortunately this one has no sound-alike.
