The label documentation for the agent in question is ambiguous on exactly this point.
The figures are clear enough; the question is what they mean and what they do not.
I can supply the numbers if the specifics change the answer.
How should I read this, and where are the traps?
The relevant detail is that escalating while symptomatic resets the tolerance process and is the mechanism behind most miserable titrations.
Holding a step for eight weeks instead of four is a legitimate approach with no efficacy cost at the destination, and it is what the trials effectively did for anyone who tolerated poorly.
The dose that produces an acceptable result with acceptable tolerability is the endpoint, not the top of the schedule. A substantial fraction of trial participants did well below the maximum.
Four to five half-lives to steady state is standard first-order pharmacokinetics and gives the four-week interval directly from the one-week half-life.
Faster titration does not reach the destination sooner in any way that matters; it reaches the symptoms sooner.
Hold rather than escalate while symptoms are active. Always.

Browse resultsAnswering this needs the agent and the current step, since the schedules differ and the reason they differ is pharmacokinetic.
Liraglutide titrates weekly rather than four-weekly because its half-life is about thirteen hours, so steady state is reached within days. The interval follows the pharmacokinetics in both cases.
Escalating while gastrointestinal symptoms are still active is the commonest avoidable error. Tolerance to the previous step has not developed, and the new step lands on top of it.
Titration schedules in the licensed products were designed specifically to manage gastrointestinal tolerability, and that intent is stated in the clinical development literature.
The top of the schedule is not the target. The working dose is.
The relevant arithmetic is that steady state takes four to five half-lives, so a one-week half-life means a four-week step interval and nothing shorter is informative.
The published semaglutide weight-management schedule steps 0.25, 0.5, 1.0, 1.7 and 2.4 mg at four-week intervals, with 0.25 mg as an initiation step rather than a therapeutic one.
Titrating downward is available too. Stepping back and holding is a normal adjustment rather than a failure.
Four half-lives between steps, minimum. Work it out for your agent.
This is the single most consequential controllable variable in the whole experience, and people routinely rush it.
The published tirzepatide schedule steps 2.5, 5, 7.5, 10, 12.5 and 15 mg at four-week intervals, with 2.5 mg as the initiation step rather than a therapeutic one.
Efficacy in the trials was dose-related but with substantial response at intermediate doses, which is why the maximum is not a target for everyone.
A schedule described here is a published schedule for a licensed product and is not a recommendation.
Stepping back is a normal adjustment, not a failure.
Answer first: the titration schedule exists to let tolerance to the gastrointestinal effects develop between steps, and every step in it is a tolerability decision rather than an efficacy one.
For an agent with a one-week half-life, steady state after a dose change is reached in about four to five weeks. Escalating at two weeks means escalating from a position you have not yet reached, and the resulting exposure is higher than the schedule intends.
Trial data show gastrointestinal adverse events concentrated in the escalation phase and declining at stable doses.
Nothing here is medical advice, and research-use compounds are not approved for human use.
Slower costs time and nothing else. The ceiling is the same.
