Insulin Dosing for Hyperglycemia Management

Evidence-Based Dosing Recommendation

The American Diabetes Association recommends administering 2-4 units of Actrapid as a correction dose for a pre-dinner blood glucose of 331 mg/dL, based on simplified sliding scale insulin guidelines for older adults 1, 2, 3
For premeal glucose >250 mg/dL but <350 mg/dL, the American Diabetes Association guidelines suggest giving 2 units of short- or rapid-acting insulin 1, 2, 3
For premeal glucose >350 mg/dL, the American Diabetes Association guidelines recommend giving 4 units of short- or rapid-acting insulin 1, 2, 3

Actrapid is a short-acting regular human insulin that should be administered 30 minutes before the meal to allow for proper onset of action, according to the American Diabetes Association 4
The American Diabetes Association guidelines state that rapid-acting insulin analogues can be given immediately before eating, differing from Actrapid 5

The American Diabetes Association guidelines explicitly state to stop sliding scale when not needed daily, indicating that this approach should only be temporary 1, 2, 3
If the patient requires correction doses daily, the underlying insulin regimen should be addressed by increasing basal insulin by 2 units every 3-7 days until fasting glucose reaches 90-150 mg/dL, as recommended by the American Diabetes Association 1, 2, 3

The American Diabetes Association recommends monitoring for hypoglycemia 2-4 hours post-injection when Actrapid action peaks, particularly in patients with impaired renal function or those on sulfonylureas 1, 3, 4, 5
The American Diabetes Association guidelines advise against using Actrapid at bedtime due to nocturnal hypoglycemia risk 1, 2, 3

The American Diabetes Association recommends a premeal target of 90-150 mg/dL for most patients, though this may be adjusted based on overall health status, age, and risk of hypoglycemia 1, 2, 3
