Novolog and Humolog are both rapid, pre-meal insulin products. Both can be given within 15 minutes of the meal. Novolog is manufactured by Novo-Nordisk and Humolog is manufactured by Eli Lilly. For the purposes of improving blood sugar after a meal, neither insulin product is considered better than the other insulin product. Because these 2 products are different from one another, they are not interchangeable either. If a person starts on Novolog, for example, it is recommended he or she continue with it.
