What is the difference between Humalog and NovoLog insulin?

Humalog and NovoLog have several differences. Humalog is insulin lispro, whereas NovoLog is insulin aspart. By contrast, doctors tend to prescribe NovoLog to people 2 years and older with type 1 or type 2 diabetes. Both medications start to work within about 15 minutes, but NovoLog tends to be slightly faster.Click to see full answer. Regarding this, can Humalog be substituted for NovoLog?Humalog and Novolog are both rapid acting. That means they work more quickly than other types of insulin. There are important distinctions between Humalog and Novolog, however, and the drugs are not directly interchangeable.Furthermore, which insulin is better NovoLog or Humalog? Overall, both Humalog and Novolog are rapid-acting insulins, so they work similarly and are equally effective. For this reason, they also have similar drug interactions and side effects. However, Novolog seems to work more quickly, and Humalog (including generic insulin lispro) is usually cheaper. Also, what is the difference between insulin lispro and insulin aspart? Insulin lispro differs from human insulin by the substitution of proline with lysine in position 28 and lysine with proline in position 29 of the B chain; insulin aspart differs from human insulin by a single substitution of proline with aspartic acid in position B28.What kind of insulin is Humalog?HUMALOG® (insulin lispro injection) is a rapid-acting human insulin analog used to lower blood glucose. Insulin lispro is produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli.
