Eugenol insulin is usually administered subcutaneously 15-20 minutes before breakfast and dinner each day. Eugenol insulin is an imported insulin, of which Eugenol 70/30 is a mixture of 70% arginine zinc recombinant human insulin, or intermediate acting insulin, and 30% recombinant human insulin, used to control blood sugar in diabetic patients. Since the duration of action of intermediate-acting insulin is about 12 hours, it is recommended to use it once in the morning and once in the evening to achieve continuous blood glucose control. In addition, since blood glucose rises rapidly after meals, subcutaneous injection 15-20 minutes before meals can effectively control blood glucose after meals. The specific dose of insulin should be determined by the endocrinologist after evaluating the patient’s blood glucose and pancreatic islet function. It is also necessary to monitor blood sugar regularly during the use of insulin to prevent hypoglycemia. In addition, eugenol is a suspension, so it must be shaken well before use.
