Glarine 100 IU/ml is a long-acting insulin analog used in the management of diabetes mellitus, both Type 1 and Type 2. It contains Insulin Glargine, a recombinant DNA-derived insulin that provides a steady and prolonged reduction in blood glucose levels. Glarine is typically administered once daily, at the same time each day, via subcutaneous injection, and it helps to control blood sugar levels throughout the day and night. It can be used alone or in combination with other antidiabetic medications. The injection is stored in a refrigerator and should not be frozen. It is essential to monitor blood glucose levels regularly to adjust the dosage.
