What is Lantus (Insulin Glargine)?
Lantus is a long-acting insulin medication that contains insulin glargine, designed to help control blood sugar levels in people with diabetes mellitus. It provides a steady release of insulin over an extended period, helping maintain stable glucose levels throughout the day and night.
It is commonly prescribed for both Type 1 and Type 2 diabetes as part of a comprehensive diabetes management plan.
How Lantus Works
Lantus mimics the body’s natural basal insulin. After injection:
- It releases insulin slowly over 24 hours
- Helps regulate blood sugar between meals and during sleep
- Reduces spikes and fluctuations in glucose levels
This consistent action supports better long-term glucose control.
Uses of Lantus
1. Type 1 Diabetes
Used alongside rapid-acting insulin to maintain baseline blood sugar levels.
2. Type 2 Diabetes

3. Long-Term Glucose Management
Provides stable insulin coverage throughout the day.
