From the Guidelines
Amaryl (glimepiride) should be initiated at a dose of 1-2 mg once daily with breakfast or the first main meal, with a maximum recommended dose of 8 mg daily, as recommended by the most recent guidelines 1. The dosing regimen for Amaryl (glimepiride) in treating type 2 diabetes should be individualized based on the patient's response to the medication.
- For most patients, the starting dose is 1 mg, which can be gradually increased by 1-2 mg every 1-2 weeks based on blood glucose response.
- Elderly patients or those with kidney or liver impairment should start with a lower dose of 1 mg daily and be titrated more cautiously to avoid hypoglycemia.
- The medication works by stimulating insulin release from pancreatic beta cells and improving insulin sensitivity in peripheral tissues, thereby lowering blood glucose levels.
- Patients should take Amaryl at the same time each day to maintain consistent blood glucose control and should be aware that hypoglycemia is a potential side effect, especially when skipping meals or increasing physical activity.
- Blood glucose monitoring is essential during dose adjustments to determine the minimum effective dose for each individual patient.
- If a patient is switching from another sulfonylurea, a gradual transition may be necessary to avoid overlapping effects, as suggested by previous guidelines 1. However, the most recent guideline 1 provides the most up-to-date recommendation for the dosing regimen of Amaryl (glimepiride).
From the FDA Drug Label
The recommended starting dose of glimepiride tablets is 1 mg or 2 mg once daily. Patients at increased risk for hypoglycemia (e.g., the elderly or patients with renal impairment) should be started on 1 mg once daily. After reaching a daily dose of 2 mg, further dose increases can be made in increments of 1 mg or 2 mg based upon the patient's glycemic response. The maximum recommended dose is 8 mg once daily.

Dose increases should be made in increments of 1 mg or 2 mg based on the patient's glycemic response, with uptitration not occurring more frequently than every 1 to 2 weeks 2. Patients at increased risk for hypoglycemia should be started on 1 mg once daily.
From the Research
Amaryl Dosing Regimen
The recommended dosing regimen for Amaryl (glimepiride) in treating type 2 diabetes is as follows:
- The effective dosage range is 1 to 8 mg/day 3
- There is no significant difference between 4 and 8 mg/day, but it should be used with caution in the elderly and in patients with renal or hepatic disease 3
- Glimepiride can be administered as monotherapy in patients with type 2 diabetes mellitus in whom glycemic control is not achieved by dietary and lifestyle modifications 3
- It can also be combined with other antihyperglycemic agents, including metformin and insulin, in patients who are not adequately controlled by sulfonylureas alone 3, 4, 5, 6, 7
Combination Therapy
- Glimepiride and metformin are effective individually in achieving a glycemic goal with a less daily insulin dose, weight gain, and hypoglycemic episodes in comparison to insulin monotherapy in subjects with type 2 diabetes mellitus 5
- The addition of glimepiride to on-going treatment with metformin and insulin in patients with known diabetes more than 10 years can be effective in lowering HbA1c and/or reducing the need for exogenous insulin 6
- Basal insulin combined oral therapy consisting of insulin and oral anti-diabetic drugs (OADs) such as metformin and glimepiride is recommended for type 2 diabetes uncontrolled on OADs 7
Safety and Efficacy
- Glimepiride is generally associated with lower risk of hypoglycemia and less weight gain compared to other sulfonylureas 3
- Glimepiride use may be safer in patients with cardiovascular disease because of its lack of detrimental effects on ischemic preconditioning 3
- The combination of glimepiride and metformin can reduce hypoglycemic episodes and weight gain in comparison to placebo 5
