What is Humulin® R U-100?
Humulin R is a polypeptide hormone that is structurally similar to human insulin produced in the body. It effectively helps manage blood sugar levels for both adults and children with type 1 and type 2 diabetes.
Insulin is a hormone produced by an organ in the body called the pancreas. Insulin is necessary for managing glucose (sugar) in the blood.
For those with type 1 and type 2 diabetes, their body’s either does not produce enough or any insulin which requires the need for insulin injections.
Humulin R U-100 is injected under the skin (subcutaneously). Insulin should not be injected into a vein or muscle. Make sure you are using a syringe marked U-100.
This short-acting insulin starts working within 30 minutes, peaks in 2-3 hours and continues to work up to 8 hours.
Through the use of insulin, patients can effectively breakdown carbohydrates, fats and proteins. With proper carbohydrate metabolism, patients can avoid the production of ketone bodies in the liver and other complications associated with diabetes.
Humulin R (insulin human recombinant) U-100 is a clear, sterile and colorless solution which contains human insulin at 100 units/mL, endogenous zinc, metacresol and water. Hydrochloric acid and/or sodium hydroxide may be added to adjust the pH levels during the manufacturing of this medication.
