What is it?
Humulin R contains regular insulin. It is the same as the insulin typically made by the body.
What is it used for?
Humulin R is used to improve glycemic control in adults and children with type 1 and type 2 diabetes mellitus.
How does it work?
Regular insulin is a short acting insulin that replaces the insulin that your body would normally make. It is a short-acting insulin, and it often used in combination with a medium- or long-acting insulin product.
Unopened vials and pens should be stored in a refrigerator, 36°F-46°F (2°C-8°C). In-use insulin can be kept at room temperature (below 86°F), away from direct heat and light. Insulin should not be stored in the freezer, and it should not be allowed to freeze. Discard if it has been frozen.
Humulin R is contraindicated in patients who have had hypersensitivity reactions to Humulin R or one of the excipients.
