What is the best course of treatment for a patient with hyperglycemia, currently on Ozempic (semaglutide), Basaglar (insulin glargine) 24 units, Novolog (insulin aspart) 4 units three times a day, and Metformin (metformin hydrochloride) 500 mg, with blood sugar levels consistently in the 250s?

Aggressive Insulin Intensification Required Immediately

This patient with blood glucose consistently in the 250s mg/dL requires immediate and aggressive upward titration of both basal and prandial insulin, along with optimization of metformin dosing. The current regimen is grossly inadequate for the degree of hyperglycemia present.

Immediate Basal Insulin Adjustment

Increase Basaglar by 4 units every 3 days until fasting glucose reaches 80-130 mg/dL. 1 For patients with fasting glucose ≥180 mg/dL (which blood glucose in the 250s clearly indicates), the evidence-based titration algorithm specifies a 4-unit increment rather than the more conservative 2-unit increase used for milder hyperglycemia. 1

• The current dose of 24 units is likely insufficient, and aggressive titration is warranted given the severity of hyperglycemia 1
• Continue this escalation pattern until fasting glucose consistently reaches target range 1
• Monitor for signs of overbasalization when the dose exceeds 0.5 units/kg/day, including bedtime-to-morning glucose differential ≥50 mg/dL, hypoglycemia, and high glucose variability 1

Critical Threshold: Prandial Insulin Intensification

The current Novolog dose of 4 units three times daily is grossly inadequate and must be increased immediately. Blood glucose levels in the 250s indicate both inadequate basal coverage AND insufficient mealtime insulin. 1

• Increase prandial insulin by 1-2 units or 10-15% every 3 days based on 2-hour postprandial glucose readings 1
• The patient likely needs significantly higher prandial doses given the degree of hyperglycemia 1
• When basal insulin approaches 0.5-1.0 units/kg/day without achieving glycemic targets, adding or intensifying prandial insulin becomes more appropriate than continuing to escalate basal insulin alone 1

Optimize Metformin Foundation Therapy

Increase metformin to at least 1000 mg twice daily (2000 mg total daily dose) unless contraindicated. 1 The current dose of 500 mg is subtherapeutic.

• The maximum effective dose is up to 2500-2550 mg/day, given in divided doses 2, 1
• Metformin should be continued when intensifying insulin therapy, as it reduces total insulin requirements and provides complementary glucose-lowering effects 1
• Titrate gradually to minimize gastrointestinal side effects, increasing by 500 mg weekly or 850 mg every 2 weeks 2
• Verify that eGFR is ≥30 mL/min/1.73 m² before increasing the dose 2

Monitoring Requirements During Intensive Titration

• Daily fasting blood glucose monitoring is essential during the titration phase 1
• Check pre-meal and 2-hour postprandial glucose to guide prandial insulin adjustments 1
• Reassess adequacy of insulin doses at every clinical visit, looking specifically for signs of overbasalization 1
• If hypoglycemia occurs, determine the cause and reduce the relevant insulin dose by 10-20% immediately 3, 1

Common Pitfalls to Avoid

Do not continue the current inadequate regimen. Blood glucose in the 250s clearly indicates the need for aggressive insulin intensification, not minor adjustments. 1

• Continuing to increase basal insulin beyond 0.5-1.0 units/kg/day without addressing postprandial hyperglycemia leads to overbasalization with increased hypoglycemia risk and suboptimal control 1
• Not optimizing metformin dosing leads to higher insulin requirements and missed opportunities for synergistic glucose lowering 1
• Delaying aggressive titration prolongs exposure to hyperglycemia and increases complication risk 1

Patient Education Essentials

• Teach recognition and treatment of hypoglycemia: treat at blood glucose ≤70 mg/dL with 15 grams of fast-acting carbohydrate 1
• Ensure proper insulin injection technique and site rotation to prevent lipohypertrophy 1
• Provide education on self-monitoring of blood glucose, "sick day" management rules, and insulin storage and handling 1

Expected Outcomes

With appropriate basal-bolus therapy at weight-based dosing and optimized metformin, significant improvement in glycemic control should be achieved within weeks. 1 The goal is to bring fasting glucose to 80-130 mg/dL and postprandial glucose to <180 mg/dL. 3, 1
