Humulin N is used to improve glycemic control in adults and children with diabetes mellitus, including Type 1 and Type 2 diabetes. It helps manage blood sugar levels when used as part of a comprehensive diabetes management plan that may include diet, exercise, and other medications.
Humulin N is an intermediate-acting insulin that contains insulin isophane suspended in a solution. After injection, it is absorbed slowly into the bloodstream, providing a longer duration of action compared to short-acting insulins. It works by binding to insulin receptors on cells, promoting glucose uptake and helping to lower blood sugar levels.
Humulin N should be administered subcutaneously and must not be used if the suspension is clumped or contains particles. It typically starts working within 1-2 hours, peaks in 4-12 hours, and can last up to 18-24 hours. Patients should monitor blood glucose regularly and be aware of hypoglycemia risk. Dosage is individualized and must be prescribed by a healthcare provider.
