Titration, properly explained

When to step up, when to hold, when to go back down, and why restarting after a gap is the one genuinely dangerous mistake.

Titration is the process of climbing from a starting dose to one that works. It is the part of GLP-1 treatment people are given least guidance on, and the part where most treatment gets abandoned.

The principle is simple: start low, go up slowly, and stop where it works. The complication is that "slowly" is a clinical judgement rather than a fixed schedule, and a lot of programmes run it as a calendar instead — which is how people end up at a dose their body was not ready for.

Why you cannot just start at the effective dose

Because your gut needs time to adapt. These drugs slow stomach emptying substantially, and going straight to a therapeutic dose produces nausea and vomiting severe enough that most people would stop within a fortnight. The starting dose buys tolerance, not results — which is why judging the medication on month one is the commonest mistake we see.

The two ladders

Step	Tirzepatide	Semaglutide
1	2.5 mg — acclimatisation	0.25 mg — acclimatisation
2	5 mg — first therapeutic dose	0.5 mg
3	7.5 mg	1 mg — therapeutic
4	10 mg — trial dose (19.5% avg)	1.7 mg
5	12.5 mg	2.4 mg — maintenance (14.9% avg)
6	15 mg — maximum (20.9% avg)	—

Each step is roughly four weeks. That is a default, not a rule, and the trial averages are averages rather than targets.

When to step up

You have been at the current dose about four weeks.
Side effects from the last increase have settled rather than merely become tolerable.
The appetite effect has faded noticeably — this is the actual signal that a step is due.
You are not in the middle of something that would make a rough fortnight unmanageable. Delaying a step around a holiday or a work deadline is entirely reasonable.

When to hold

Holding at your current dose for an extra month is a normal clinical decision, not a failure. Hold if side effects have not settled, if you are still losing weight steadily at this dose, or if you simply do not feel ready. A programme that pushes you up regardless is running a schedule rather than treating you.

Read this bit. Holding should be free. On a programme that prices by dose, staying put can feel like paying the same for less — which is a financial pressure on a clinical decision. 6 providers in our table hold one price across the entire ladder, which removes that pressure entirely. See our price tables.

When to step back down

Going down a rung is a legitimate move and an under-used one. Reasons to consider it: side effects that have not settled after several weeks at a dose, appetite suppression so complete that you cannot eat enough protein, or having reached your goal and wanting a maintenance dose rather than a maximum one. Discuss it with your prescriber rather than simply taking less than you were prescribed.

Restarting after a gap

This is the one part of titration with a genuine safety hazard. Tolerance fades when you stop. If you have missed several weeks — through a supply problem, a lapsed subscription or a holiday — you generally should not resume at the dose you were on. Restarting high after a gap is how people end up severely unwell.

Missed one dose and remembered within a few days: generally take it and carry on. Ask your provider for their specific guidance.
Missed one dose and the next is nearly due: generally skip it rather than doubling up. Never take two doses close together.
Missed several weeks: contact your prescriber before restarting, and expect to step back down.
Changed products or concentrations: treat it as a fresh conversation, not a continuation.

What a good programme does

Reviews each increase against how you are actually doing, rather than applying it on a timer.
Makes holding easy to request and does not charge you more for it.
Answers within days when a dose goes badly, not at the next scheduled appointment.
Asks before escalating rather than shipping the next dose automatically.
Has a clear position on what happens if you miss weeks.

Questions worth asking before you start

How are dose increases decided — by a clinician reviewing my progress, or on a schedule?
What happens to my price when my dose goes up?
How do I request to stay at a dose for longer, and does that cost me anything?
Who do I contact if an increase goes badly, and how quickly do they respond?
What is your protocol if I miss two or three weeks?

Common questions

How long does titration take overall?

Reaching the top of the tirzepatide ladder takes around five months on a standard four-week schedule; semaglutide takes around four. Many people never reach the top, and do not need to.

Is it bad if I stay on a low dose?

No. 5 mg tirzepatide and 1 mg semaglutide are both genuinely therapeutic, and settling at a dose you tolerate beats reaching a maximum you abandon. The goal is the effect, not the number.

Can I titrate faster to get results sooner?

It is not advisable and a responsible prescriber will decline. The schedule exists to keep side effects survivable; compressing it mostly produces people who stop taking the medication.
