Four dose steps in, holding each one the full four weeks, and I am trying to work out whether the interval is a pharmacological requirement or a tolerability convention.
What I am trying to establish is what the trials actually did with participants who could not tolerate a step, because that is the situation I am in and the protocol summaries skip it.
I have searched first, so if this is covered somewhere point me at it and I will read it.
This one has a reasonably settled answer, so here it is. The trials generally allowed a step to be held or reduced and then retried, and people who did that mostly arrived at the same place a few weeks later. The end point of the ladder is set by tolerability, not by a schedule, and there is no evidence that reaching the top faster produces a better outcome.

That is right for the weekly injectables. For the daily agents the interval logic is different and the four-week convention does not transfer.

Can confirm the pattern Dr.ObesityMed describes. Four weeks is the pharmacokinetics, not caution. With a one-week half-life you need four to five half-lives to reach steady state, so at two weeks you are dosing on top of a concentration that has not finished rising. Escalating then stacks exposure and you get the side-effect burden of the higher dose before you have seen the benefit of the current one.
Adding the clinical framing, because it changes how the question reads.
Dose escalation anxiety for titration: I was terrified to move from 0.5mg to 1.0mg based on horror stories in this forum. But my actual experience? Slightly more appetite suppression, zero additional side effects.
Remember that the people posting about terrible side effects are a biased sample. Most people titrate up without drama — they just don't post about it because it's uneventful.
