MONOTHERAPY (if no contraindications) EFFICACY: High RISK: Low WEIGHT: Neutral/Weight Loss CV EFFECT: Beneficial SIDE EFFECTS: GI/Lactic Acidosis COST: $

Check A1c in three months. If the patient is not at program target of < 8 percent, consider two-drug combination (choice dependent on the individual patient and disease-specific factors).

IF PATIENT CAN'T TOLERATE/CONTRAINDICATION TO METFORMIN: GLP-1 or SGLT-2 Inhibitor (SGLT2i) + basal Intolerance: Use extended release formulation. Take with food. Titrate dose slowly. Go back to prior tolerated dose if excessive side effects, GI side effects will generally lessen with time. Contraindication: Updated safety labeling says safe to use in patients with eGFR > 30 mL/min/1.73m^2

DRUG ORDER KEY: GREEN YELLOW RED = progression of most to least preferred

PATIENT SCENARIO PREFERRED DRUG(S) NOTES

Refuses to administer Avoid using insulin as a threat or sign of failure. Patient education is key. Discuss with patient injections that diabetes is a progressive disease and injection therapies are important for glycemic control, teach patient about proper injection techniques, self-monitoring of glucose, recognizing signs and symptoms of hypoglycemia and how to treat it. High CV risk or metformin+SGLT2i or GLP-1 Metformin, SGLT2i (Farxiga®, Invokana®, Jardiance®) and GLP-1 established CV disease (Ozempic®, Rybelsus®, Trulicity®, Victoza®) have evidence for decreasing CVD events. Farxiga®, Invokana® and Jardiance® have evidence for reducing HF and/or CKD If further intensification needed, consider adding the other class (SGLT2i or GLP-1). Uncontrolled on oral therapy GLP-1 + metformin +/- basal insulin Metformin should be continued as long as not contraindicated.

Sulfonylureas and TZDs should only be used with caution. Both agents are associated with clinically significant weight gain, and also have a significant risk of causing hypoglycemia. However, it is recognized that these agents may be considered for use in selected patients when a lower-cost alternative is absolutely necessary.
