Tirzepatide Dosing: How Titration Works
Why tirzepatide is stepped up gradually, and how the dual-agonist medication is managed over time.
Tirzepatide is a once-weekly medication that acts on two gut-hormone receptors, GLP-1 and GIP. Like semaglutide, its dose is increased gradually under provider supervision rather than fixed from the start.
This guide explains how titration generally works for tirzepatide and why your schedule should come from a licensed provider.
A dual-receptor medication
Tirzepatide acts on both the GLP-1 and GIP receptors, which is why it is called a "dual agonist." It is the molecule in brand-name Zepbound (for weight management) and Mounjaro (for type 2 diabetes). As with any GLP-1-class medication, the dose is built up over time.
How titration works
- Treatment starts at a low dose and is increased gradually under provider supervision.
- Each step gives your body time to adjust and helps limit side effects.
- Your provider may hold a dose longer or adjust it based on tolerability and response.
About compounded medications
Compounded semaglutide and tirzepatide are prepared by state-licensed 503A compounding pharmacies for an individual patient after a provider consultation. They are not FDA-approved, are not reviewed by the FDA for safety or effectiveness, and are only appropriate when a licensed provider determines they are clinically suitable for you.
Tirzepatide vs. semaglutide dosing
Tirzepatide and semaglutide are different molecules with different dosing ladders, so one is not simply a substitute for the other at the same numbers. If you are switching or choosing between them, that transition is planned by your provider based on your history and how you have tolerated treatment.
If you miss a dose
Do not double up. Your provider’s guidance depends on how much time has passed since the missed dose — contact your care team if you are unsure.

Is tirzepatide dosed the same as semaglutide?
No. They are different molecules with different titration schedules. A provider sets each schedule individually, and switching between them is a planned clinical decision.
Why is tirzepatide increased gradually?
Gradual titration helps your body adjust and limits side effects. The dose is built up toward an effective, tolerable level under provider supervision.
Is compounded tirzepatide FDA-approved?
No. Compounded tirzepatide is prepared by a state-licensed 503A pharmacy for an individual patient and is not FDA-approved. A licensed provider decides whether it is appropriate for you and manages your dosing.
