Synjardy Contraindications and Alternatives in Autoimmune Diabetes

Regulatory and Guideline Position

The American Diabetes Association Standards of Care explicitly state that SGLT2 inhibitors like empagliflozin are approved only for Type 2 diabetes treatment 1
European guidelines recommend empagliflozin, canagliflozin, or dapagliflozin specifically in patients with Type 2 diabetes and cardiovascular disease or high cardiovascular risk 2
Synjardy is FDA-approved exclusively for Type 2 diabetes mellitus, not Type 1 diabetes or autoimmune diabetes 1

SGLT2 inhibitors significantly increase the risk of diabetic ketoacidosis (DKA) in patients with Type 1 diabetes or insulinopenic diabetes 3
The FDA issued a specific warning that SGLT2 inhibitors may lead to euglycemic diabetic ketoacidosis, which is particularly dangerous because it can occur without significant hyperglycemia 4
In Type 1 diabetes, concomitant use of insulin and SGLT2 inhibitors substantially increases DKA risk 3

Insulin remains the cornerstone of treatment for Type 1/autoimmune diabetes 1
Pramlintide is the only non-insulin injectable agent FDA-approved for Type 1 diabetes in adults, showing modest A1C reductions of 0.3-0.4% 1

In patients with autoimmune diabetes, the use of SGLT2 inhibitors like empagliflozin creates a metabolic environment that promotes ketogenesis through enhanced urinary glucose excretion, reducing available substrate, and relative insulin deficiency in the setting of increased glucagon activity 5
Basal insulin alone can be initiated at 10 units per day or 0.1–0.2 units/kg/day, depending on the degree of hyperglycemia, as recommended by the American Diabetes Association 5
Long-acting basal analogs (U-100 glargine or detemir) are preferred over NPH insulin when adding basal insulin, with a recommended starting dose of mealtime insulin being 4 units, 0.1 units/kg, or 10% of the basal dose 5

Many individuals with autoimmune diabetes require mealtime bolus insulin dosing in addition to basal insulin, with rapid-acting analogs preferred due to their prompt onset of action 5
