Quick answer
The gradual dose escalation schedule used when starting GLP-1 therapy. Typically increases every 4 weeks to reach the maintenance dose, minimizing GI side effects.
Full definition
Titration is the stepwise increase in GLP-1 dose over weeks to months, designed to allow GI tolerance to develop. For Wegovy, the standard schedule is 0.25 mg weekly for 4 weeks, then 0.5, 1.0, 1.7, and 2.4 mg, escalating every 4 weeks (full titration = 16-20 weeks). For Mounjaro/Zepbound, the schedule is 2.5 mg weekly for 4 weeks, then 5, 7.5, 10, 12.5, and 15 mg. Some patients tolerate faster escalation; others need extended pauses at a tolerated dose. Skipping titration steps substantially increases nausea, vomiting, and discontinuation risk.

Titration: complete reference
Dose titration in GLP-1 therapy refers to the gradual stepwise increase of medication dose from a low starter level to the maintenance dose — designed to minimize gastrointestinal side effects (nausea, vomiting, diarrhea) that occur most intensely with rapid dose escalation. For Wegovy (semaglutide 2.4mg), the standard titration is 0.25 → 0.5 → 1.0 → 1.7 → 2.4 mg, with each step lasting at least 4 weeks (total titration: 16 weeks). For Zepbound (tirzepatide 15mg), the schedule is 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg over 20 weeks minimum. The 4-week minimum at each step is not arbitrary — it represents the threshold below which patient discontinuation rates spike substantially. Some prescribers extend titration intervals to 6-8 weeks for patients with greater GI sensitivity. Skipping steps or accelerating titration is associated with significantly worse tolerability and higher dropout rates. After reaching maintenance, dose-reduction strategies may be used to maintain weight while reducing side effects long-term.
- In practice
- If you start Wegovy at the 2.4mg maintenance dose immediately, severe nausea and GI side effects are far more likely and most people would not tolerate it. Starting at 0.25mg and stepping up over 16 weeks gives your body time to adapt — most patients tolerate the full titration with manageable symptoms.
- Clinical context
- Clinicians use titration to balance efficacy with tolerability. Slower titration improves adherence; faster titration accelerates outcomes but risks discontinuation.
