From the Research

Zepbound (tirzepatide) is not FDA-approved for the treatment of type 2 diabetes, and the recommended dosing for type 2 diabetes is actually for Mounjaro (tirzepatide), which is 2.5 mg injected subcutaneously once weekly for 4 weeks, then increased to 5 mg once weekly, and further increased in 2.5 mg increments every 4 weeks up to a maximum of 15 mg once weekly, based on glycemic response and tolerability, as supported by the SURPASS clinical trials 1, 2, 3. The dosing strategy for tirzepatide is designed to minimize gastrointestinal side effects, which are common with this medication.

  • The starting dose of 2.5 mg helps to reduce the risk of adverse events, such as diarrhea and nausea.
  • The gradual titration approach allows for individualized dosing, based on the patient's glycemic response and tolerability.
  • The maximum dose of 15 mg once weekly has been shown to provide significant improvements in glycemic control, as well as weight loss and other cardiovascular benefits, as demonstrated in the SURPASS clinical trials 1, 2, 3. It's essential to note that tirzepatide works as a dual GIP/GLP-1 receptor agonist, which helps improve insulin secretion, reduce glucagon levels, slow gastric emptying, and promote satiety, all contributing to improved glycemic control in type 2 diabetes patients.
  • The medication has been shown to be effective in reducing HbA1c levels, as well as body weight, and improving cardiovascular risk factors, such as blood pressure and lipid profiles 2, 3.
  • The safety profile of tirzepatide is generally similar to other GLP-1 receptor agonists, with a low risk of hypoglycemia when used without insulin or insulin secretagogues 3. However, it's crucial to consider the potential risks and benefits of tirzepatide, as well as the individual patient's needs and medical history, when determining the optimal dosing strategy.
  • The medication should be used under the guidance of a healthcare professional, with regular monitoring of glycemic control, weight, and other cardiovascular risk factors.
  • Patients should be educated on the proper use of tirzepatide, including the importance of gradual titration, and the potential risks and benefits of the medication.
