Overview
Duopharma Insugen-N 30/70 (100IU/ml) Cartridge is a premixed biphasic human insulin 100IU/ml cartridge, containing 30% soluble (regular) human insulin and 70% isophane (NPH) human insulin. This product is manufactured by Biocon and marketed by Duopharma as the Insugen-N brand of premixed insulin. It is used to help control blood glucose levels in people with diabetes who require insulin therapy, combining a fast-acting and an intermediate-acting component in a single injection.
The soluble portion starts working soon after injection to cover the rise in blood glucose after a meal, while the isophane portion is absorbed more slowly to provide a longer background level of insulin action between meals.
How it Works
The soluble (regular) component of this premixed insulin acts quickly to lower the rise in blood glucose that follows a meal, while the isophane (NPH) component is absorbed gradually, providing a steadier background level of insulin action over several hours. Together, they help cover both mealtime and between-meal blood glucose needs from a single injection.
Directions for Use
Before use, gently roll the Duopharma Insugen-N 30/70 (100IU/ml) Cartridge cartridge between your palms and invert it several times to re-suspend the cloudy mixture evenly – do not shake it vigorously, as this can create air bubbles and affect dosing accuracy. Inject it subcutaneously (under the skin) into the abdomen, thigh, or upper arm before a meal, according to the regimen your doctor has set, and rotate the injection site with each dose.
Dosage
The dose of Duopharma Insugen-N 30/70 (100IU/ml) Cartridge is individualised by your doctor based on your blood glucose readings, diet, activity level, and overall diabetes management plan. It is usually injected once or twice daily before meals, as directed by your doctor. Never change your dose without medical guidance.

Frequently Asked Questions
