What is Novolin R Penfill?
Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. Regular insulin is a short-acting insulin that starts to work within 30 minutes after injection, peaks in 2 to 3 hours, and keeps working for up to 8 hours.
Regular insulin is used to improve blood sugar control in adults and children with diabetes mellitus. This medicine may be used for type 1 or type 2 diabetes.
Regular insulin may also be used for purposes not listed in this medication guide.
Warnings
You should not use this medicine if you are allergic to insulin, or if you are having an episode of hypoglycemia (low blood sugar).
Regular insulin is not approved for use by anyone younger than 2 years old. Regular insulin should not be used to treat type 2 diabetes in a child of any age.
Tell your doctor if you have ever had:
- liver or kidney disease; or
- heart failure.
Taking certain oral diabetes medicines while using insulin may increase your risk of serious heart problems. Tell your doctor if you also take medicine that contains pioglitazone or rosiglitazone.
Tell your doctor if you are pregnant or breastfeeding.
Follow your doctor's instructions about using insulin if you are pregnant or you become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications in both the mother and the baby.
