What they say

Humulin R (insulin [human recombinant]) and Humalog (insulin lispro injection) are forms of insulin indicated as adjuncts to diet and exercise to improve glycemic control in adults and children with type 1 and type 2 diabetes mellitus. Humulin R is a form of short-acting insulin and Humalog is a rapid-acting human insulin analog. Humulin R is a brand-name medication that’s available both over the counter and by prescription. It’s used to help manage blood sugar levels in adults and children with either type 1 or type 2 diabetes.

How Do You Use This Medication?

HUMULIN R This comes as a liquid solution. It’s given as an injection under your skin (called a subcutaneous injection). You’ll give the injections to yourself once your doctor has shown you how to administer the medication. Humulin R is available in two strengths:
· Humulin R U-100. This strength contains 100 units of insulin per 1 milliliter (mL) of solution. It comes in 3-mL and 10-mL vials.
· Humulin R U-500. This strength contains 500 units of insulin per 1 mL of solution. It comes in a 20-mL vial. It’s also available as a 3-mL KwikPen which is a prefilled pen that’s meant to be used by only one person.

Are Humulin and Humalog the same thing?
Although both Humulin and Humalog are insulins, Humalog is a human insulin analog which means the structure of the insulin has been modified to allow it to be absorbed more quickly than non-analog insulins. By switching around the sequence of two amino acids (proline at B-28 and lysine at B-29), Humalog is absorbed more rapidly and lasts for a shorter period than Humulin. This means Humalog insulin can be administered within 15 minutes of a meal which makes it more convenient to dose and less likely to cause hypoglycemia.
What are the similar side effects of Humulin R and Humalog?
Side effects of Humulin R and Humalog that are similar include low blood sugar (hypoglycemia) (symptoms include headache, hunger, weakness, sweating, tremors, irritability, trouble concentrating, rapid breathing, fast heartbeat, fainting, and seizures [severe hypoglycemia can be fatal]) and injection site reactions (e.g., pain, redness, irritation).
