What is the initial treatment for diabetes?

From the Guidelines

The initial treatment for diabetes should include metformin and comprehensive lifestyle modification, unless there are contraindications, as it is effective, safe, and may reduce the risk of cardiovascular events and death 1.

Key Considerations

• Metformin is the preferred initial pharmacologic agent for the treatment of type 2 diabetes, to be started at the time of diagnosis unless contraindicated, and should be continued as long as it is tolerated and not contraindicated 1.
• Lifestyle modifications, including a balanced diet, regular physical activity, and weight loss if overweight, are essential components of the initial treatment approach for type 2 diabetes.
• The choice of pharmacologic agents should be guided by a patient-centered approach, considering factors such as efficacy, hypoglycemia risk, impact on weight, potential side effects, renal effects, delivery method, cost, and patient preferences 1.

Treatment Approach

• For type 2 diabetes, metformin is usually the first-line medication, with a starting dose of 500 mg once or twice daily with meals, gradually increasing to a typical dose of 1000-2000 mg daily divided into two doses to minimize gastrointestinal side effects.
• For type 1 diabetes, insulin therapy is essential from diagnosis, typically using a combination of long-acting insulin and rapid-acting insulin before meals.
• Blood glucose monitoring is crucial for all diabetes patients, with target fasting glucose of 80-130 mg/dL and post-meal levels below 180 mg/dL.

Special Circumstances

• Additional and/or alternative agents may be considered in special circumstances, such as in individuals with established or increased risk of cardiovascular or renal complications 1.
• The early introduction of insulin should be considered if there is evidence of ongoing catabolism, symptoms of hyperglycemia, or high A1C levels 1.

From the FDA Drug Label

The main goal of treating diabetes is to lower your blood sugar to a normal level. High blood sugar can be lowered by diet and exercise, and by certain medicines when necessary.

The initial treatment for diabetes includes diet and exercise, and certain medicines when necessary, with the main goal of lowering blood sugar to a normal level 2.

• Diet: to help manage blood sugar levels
• Exercise: to help lower blood sugar
• Medicines: such as metformin or glimepiride, may be prescribed when necessary to help lower blood sugar 2 3

From the Research

Initial Treatment for Diabetes

The initial treatment for diabetes, specifically type 2 diabetes, often involves a combination of lifestyle changes and medication.

• The primary goal is to achieve and maintain good glycemic control, which can help prevent complications associated with diabetes.
• According to 4, basal insulin combined with oral anti-diabetic drugs (OADs) such as metformin and glimepiride is recommended for type 2 diabetes that is uncontrolled on OADs alone.
• Studies have shown that the combination of metformin and glimepiride with insulin can be effective in achieving glycemic control, with benefits including reduced daily insulin dose, less weight gain, and fewer hypoglycemic episodes 5, 6.

Medication Options

Several medication options are available for the initial treatment of type 2 diabetes, including:

• Metformin, which is often the first-line treatment due to its efficacy and safety profile
• Glimepiride, a sulfonylurea that can be used alone or in combination with metformin
• Insulin, which may be added to oral therapy if glycemic control is not achieved with OADs alone
• Research has also explored the use of other medications, such as sodium-glucose cotransporter-2 inhibitors (SGLT2i) and dipeptidyl peptidase-4 inhibitors (DPP4i), as second-line treatments 7.

Combination Therapy

Combination therapy, involving the use of multiple medications, can be an effective approach for achieving glycemic control in type 2 diabetes.

• The combination of metformin and glimepiride with insulin has been shown to be effective in reducing HbA1c levels and improving glycemic control 6, 8.
• The choice of combination therapy should be individualized based on patient characteristics, such as age, baseline HbA1c, and presence of comorbidities 7.
