From the Guidelines

When transitioning from Ozempic (semaglutide) to Mounjaro (tirzepatide), the recommended approach is to discontinue Ozempic and start Mounjaro at the initial dose of 2.5 mg or 5 mg once weekly, with a gradual titration upward as needed and tolerated. The dosing strategy for Mounjaro, as per the latest evidence 1, involves starting with a lower dose and gradually increasing it to minimize gastrointestinal side effects. The properties of GLP-1RA and GIP, as outlined in the study 1, highlight the importance of careful dose escalation due to Mounjaro's dual mechanism of action. Key points to consider when transitioning include:

  • Discontinuing Ozempic and starting Mounjaro one week later, without an overlap period, to minimize the risk of additive side effects
  • Starting Mounjaro at an initial dose and gradually titrating upward as needed and tolerated, with each dose level maintained for at least 4 weeks before considering further increases
  • Monitoring for gastrointestinal side effects like nausea, vomiting, and diarrhea, and adjusting the dose accordingly. The study 1 provides valuable insights into the pharmacokinetics and pharmacodynamics of Mounjaro, including its bioavailability, volume of distribution, and elimination half-life, which inform the recommended dosing strategy. Overall, the goal of the transition is to maintain therapeutic coverage while minimizing the risk of adverse effects, and the recommended approach is based on the latest evidence and expert consensus 1.

From the Research

Dosing Strategy for Transitioning from Ozempic to Mounjaro

When transitioning from Ozempic (semaglutide) to Mounjaro (tirzepatide), several factors should be considered, including the patient's current dose of Ozempic and their individual response to the medication.

  • The recommended dosing strategy for Mounjaro is to start with a dose of 2.5 mg or 5 mg once weekly, with the option to titrate up to 10 mg or 15 mg once weekly based on the patient's response and tolerability 2, 3.
  • Patients who are transitioning from Ozempic 2 mg may be able to start with a higher dose of Mounjaro, such as 10 mg or 15 mg once weekly, depending on their individual response to the medication and their tolerability of gastrointestinal side effects 3, 4.
  • It is essential to monitor patients closely during the transition period and adjust the dose of Mounjaro as needed to minimize the risk of gastrointestinal side effects and ensure optimal glucose control 2, 3, 4.
  • The choice of dose for Mounjaro should be based on the patient's individual needs and response to the medication, as well as their medical history and current health status 5, 6.

Key Considerations for Transitioning from Ozempic to Mounjaro

Some key considerations for transitioning from Ozempic to Mounjaro include:

  • The patient's current dose of Ozempic and their response to the medication
  • The patient's medical history and current health status
  • The potential for gastrointestinal side effects and the need for dose titration
  • The importance of monitoring patients closely during the transition period and adjusting the dose of Mounjaro as needed
  • The need for individualized treatment planning and dose selection based on the patient's unique needs and response to the medication 2, 3, 4, 5, 6.
