Glargine insulin is available in two sizes: insulin refill and pre-filled. The price of glargine insulin refill is around 170 RMB, and the price of glargine insulin pre-filled is around 200 RMB, which varies slightly from hospital to hospital. Lysodren, also known as glargine insulin injection, is a long-acting insulin analogue that can be injected subcutaneously once a day at any time of the day to provide basal insulin, mainly for fasting blood sugar control. Glargine insulin lasts for a long time and can be maintained for 24 hours without any obvious peak effect, so the incidence of hypoglycemia is low, and it can effectively control fasting blood sugar and improve the dawn phenomenon. However, when using glargine insulin, it is necessary to combine with oral hypoglycemic drugs or three pre-meal rapid-acting insulins to effectively control fasting and post-meal blood glucose and promote the achievement of glycated hemoglobin standard.
