🔹 Dosing Protocol

Critical Notes:

• 5 mg is where significant metabolic effects begin

• Continue for at least 4 weeks before considering increase

• Some patients may stay at 5 mg long-term if:

  • A1c targets are met

---

• Fasting glucose decrease: 40-60 mg/dL

Weight Loss:

• Month 1 (2.5 mg): 2-5% body weight

• Month 2 (5 mg): 5-9% body weight

🔹 Clinical Monitoring

At This Dose:

• Check A1c after 8 weeks (2 months)

• Monitor for hypoglycemia if on insulin/sulfonylureas

• Assess tolerance at week 6 (mid-dose period)

Renal Considerations:

• No dose adjustment needed for mild/moderate CKD

• Use caution if eGFR <30 (limited data)

🔹 Cost & Access

Prescribing Tip: Many insurers require:

1. T2D diagnosis +

2. Step therapy (metformin failure)

• Trulicity/Dulaglutide:

  • If on 1.5 mg → Start at 5 mg

  • If on 3-4.5 mg → Start at 7.5 mg

To Zepbound:

• Direct 1:1 conversion possible

• Requires new prescription (different indications)
