Semaglutide and Tirzepatide Titration, Week by Week
Starting doses are a formality. What matters is the schedule that follows, and how willing your provider is to change it.
Titration is the staged increase from a starting dose to whatever dose actually works for you. The starting dose is deliberately too low to produce results — it exists to test tolerance. From there, increases are driven by response and side-effect load, not by the calendar, and most patients settle below the maximum available dose and stay there.
Why the first dose is not meant to work
Every GLP-1 protocol begins at a dose too low to do much. That is deliberate. The starting dose tests whether you tolerate the drug class at all, and it lets the gastrointestinal effects settle before anything is asked of them.
Patients who judge the medication by their first few weeks are judging the wrong thing. Very little about weeks one to four predicts the outcome except whether you were able to keep taking it.
What a schedule is and is not
A standard escalation steps up at fixed intervals, commonly monthly. That interval is a default, not a mandate, and treating it as a mandate is the most common titration error we see.
If nausea is limiting the quality of your food, or side effects are interfering with your week, holding a dose for an extra cycle is not a setback. It is the protocol working as designed. The schedule serves the patient, not the other way round.
The goal is the lowest dose that still produces change. Not the highest dose you can tolerate.
What we watch between steps
Three things decide whether a dose increases: appetite signal, side-effect load, and rate of loss. When appetite suppression is holding and weight is moving at a reasonable pace, there is no clinical reason to escalate.
Dose increases are for stalls, not for calendars. Escalating a dose that is already working trades a better side-effect profile for nothing, and it removes headroom you may want later.
Where most people land
Most patients settle below the maximum labelled dose and stay there. That is the intended outcome, not an underperformance. Titration is the process of finding your number, and it is finished when your number stops changing.
There is also a floor to this. A dose that produces no appetite change and no movement after a fair trial is not the right dose, and staying on it out of caution wastes months. Underdosing and overdosing are both errors; the schedule exists to find the space between them.
Common questions
How long does titration take?
It varies. Standard escalations step up at roughly monthly intervals, so reaching a maintenance dose commonly takes several months. Holding a dose longer because of side effects extends that, and is a normal part of the process rather than a delay.
What happens if I miss a dose during titration?
Contact your provider rather than doubling up. Depending on how long the gap was, the plan may be to resume at the same dose or to step back down, because tolerance to gastrointestinal effects fades faster than most people expect.
Do I have to reach the maximum dose?
No. Most patients settle below the maximum available dose. The aim is the lowest dose that still produces change, because that dose has the best side-effect profile and leaves headroom for later.
