Humulin 70/30 – Premixed Human Insulin Injection (10ml Vial)
**Humulin 70/30** is a premixed insulin formulation containing **70% NPH insulin (isophane insulin)** and **30% regular human insulin**. It is used to improve blood sugar control in people with diabetes mellitus. This intermediate-acting insulin is designed for **subcutaneous injection** and provides both fast and prolonged blood glucose-lowering effects — making it ideal for once or twice daily use before meals.
Active Ingredients
- 70% Isophane Insulin (NPH) – Intermediate-acting
- 30% Regular Human Insulin – Short-acting
How It Works
The regular insulin component starts working within 30 minutes of injection, peaking around 2–4 hours, while the NPH component provides extended control for up to 18–24 hours. Together, they help maintain stable blood glucose levels throughout the day and night.
Uses of Humulin 70/30
- Management of type 1 and type 2 diabetes mellitus
- Helps control post-meal blood sugar spikes and maintain fasting glucose levels
- Used when combination therapy is preferred over separate insulin injections
