Why titration exists
GLP-1 medications work by slowing gastric emptying and altering appetite signaling. Starting at a full dose would overwhelm your GI system, causing severe nausea and vomiting in most patients. Titration lets your body adapt gradually, building tolerance while the medication's weight loss benefits accumulate.
Semaglutide (Wegovy) titration schedule
| Weeks | Dose | Typical Experience |
|---|---|---|
| 1–4 | 0.25mg | Mild appetite change, possible light nausea. Titration dose — minimal weight effect. |
| 5–8 | 0.5mg | Appetite reduction more noticeable. Brief nausea flare days 1–3 after increase. |
| 9–12 | 1.0mg | Meaningful appetite suppression. Weight loss typically accelerates here. |
| 13–16 | 1.7mg | Strong appetite regulation. Most GI adaptation complete by now. |
| 17+ | 2.4mg | Maintenance dose. Maximum weight loss effect. Side effects generally minimal. |
Tirzepatide (Zepbound) titration schedule
| Weeks | Dose | Typical Experience |
|---|---|---|
| 1–4 | 2.5mg | Starting dose. Similar to semaglutide 0.25mg in initial adjustment. |
| 5–8 | 5mg | First therapeutic dose for some patients. Noticeable appetite reduction. |
| 9–12 | 7.5mg | Many patients see significant weight loss acceleration here. |
| 13–16 | 10mg | Strong response for most patients. Some achieve optimal results without going higher. |
| 17–20 | 12.5mg | Near-maximum efficacy with manageable side effects for most. |
| 21+ | 15mg | Maximum dose. Highest average weight loss in trials. Not all patients need this level. |
When to slow down
The titration schedule is a guide, not a mandate. You should extend time at your current dose (rather than escalating) if nausea or vomiting persists beyond 2 weeks at the current dose, GI symptoms are affecting your ability to eat, drink, or function, or you're losing weight well at the current dose and don't need more suppression.
Staying at a lower dose longer is almost always better than pushing through intolerable side effects. Research shows that aggressive titration increases dropout rates without improving long-term outcomes.
You may not need the maximum dose
Not every patient needs or benefits from the highest available dose. Some patients achieve excellent results at semaglutide 1.7mg or tirzepatide 10mg with fewer side effects than they'd experience at the maximum. Your provider should evaluate your response at each level and discuss whether escalation is adding benefit or just adding side effects. The goal is the lowest effective dose, not the highest tolerable one.
