How to Build a GLP-1 Titration Schedule
How GLP-1 dose escalation works, how to lay your provider's plan out as a schedule you can follow, and what to record so the next increase is informed.
What titration is
GLP-1 medications are not started at their full dose. Treatment begins low and steps up over weeks or months, a process called titration. The low starting dose is not the therapeutic target; it exists so your body can adjust, because side effects are consistently worse when the dose rises quickly.
Every step, every interval and every decision to move up belongs to you and your provider. What this guide covers is keeping track of the plan you were given, so that when a decision point arrives you can answer the question it turns on.
Why write it down at all
A titration plan is usually explained once, in an appointment, and then has to survive several months of ordinary life.
It is genuinely easy to lose track of which week you are in. The schedule is described in relative terms — "four weeks at this, then we'll go up" — and relative terms decay. Add one postponed step, which happens to almost everyone, and the mental version stops matching reality within a fortnight.
Writing it out converts "we'll go up every four weeks" into specific dates on specific days. That is much harder to drift from, and it is much easier to correct when something moves.
Building the schedule
Start with your fixed shot day. Most GLP-1 medications are weekly, and keeping the same day each week is what makes everything else legible — the side effect pattern, the weight trend, the whole record.
Lay the dose steps against that day. For each step, record the dose, the date it starts, and the date the next increase is due if all goes normally.
Mark the appointments. Note where each review falls. These are the real decision points; the increase dates are provisional and the appointments are where they get confirmed.
The output should be something you can look at once a week and know exactly where you are. Something like this:
| Step | Dose | Starts | Next due | Review |
|---|---|---|---|---|
| 1 | 0.25 mg | 6 Mar | 3 Apr | — |
| 2 | 0.5 mg | 3 Apr | 1 May | 10 Apr |
| 3 | 1.0 mg | 1 May | 29 May | — |
| 4 | 1.7 mg | 29 May | 26 Jun | 5 Jun |
Doses and intervals in that table are illustrative. Yours come from your provider and from the instructions supplied with your specific medication — the standard schedules differ between semaglutide and tirzepatide, which is covered in the comparison of the two.
Why the week after an increase is not the worst one
This one surprises people and it is worth building into your expectations before you need it.
Because these medications have a long half-life, levels keep accumulating for roughly four to five weeks after any change before they plateau. A dose increase does not land as a step; it lands as a ramp. So the week immediately after a step up is often unremarkable, and weeks two through four are frequently harder.
The practical consequence is that judging a new dose on its first week is judging it too early — and that a rough patch in week three does not mean something has gone wrong. The half-life explainer covers the arithmetic.
It also means that on a standard four-week schedule you may never quite reach a plateau before the next increase. That is normal and worth knowing before you conclude that a difficult month means the treatment is not suiting you.
What to record at each step
The schedule is the plan. What makes it useful three months later is what you record against it:
- Side effects at that dose, and whether they settled — the side effect guide covers the fields worth having.
- Appetite, and how the pattern across the week changed. Food noise returning earlier in the week is a common thing to notice after a step.
- Weight trend over the step, not a single reading.
- Anything that made a week unrepresentative — illness, travel, a missed dose, a holiday.
By the time you are deciding whether to go up again, you want the last step's record in front of you rather than a general impression of it. That is the entire purpose of writing it down.
A useful discipline: at the end of each step, add one line summarising it. "0.5 mg, four weeks: nausea 3/5 on days 2–3 for the first two weeks, settled after that. Down 2.1 kg. One late dose, 14 April." That single line is what you will actually read back.
Expect the plan to change
Titration schedules are provisional by design. Staying at a dose longer than planned because side effects have not settled is a normal, expected outcome — not a setback and not a failure to follow the plan.
When that happens, redraw the schedule. The common mistake is keeping the original dates and mentally applying a correction to them, which stops working after the second adjustment and leaves you unsure which week you are in.
Other things that move the dates:
- A missed or late dose. Record it and check whether it shifts the step.
- A supply gap. More common than it should be. This is where tracking your vials and refills earns its keep, because the reorder point moves every time you step up and consumption rises.
- A step down. Stepping back after a rough increase is a routine decision and most tracking tools handle it badly — they assume you only ever go up. Record it explicitly.
- A non-standard interval. If your schedule is not a clean weekly one, tracking a non-standard schedule covers what changes.
Bring it to appointments
A provider deciding whether to increase your dose is asking how the current one has gone. A schedule with the record attached answers that in seconds, and answers it with specifics rather than with how the last few days happened to feel.
Two things to have ready: the one-line summary of the current step, and whether anything unrepresentative happened during it. That is usually enough to make the decision a real one. The guide on preparing for a GLP-1 appointment covers the rest of the page.
Before you leave, write down the new dose, the next step date and the review date. It takes seconds and it is the most common source of confusion between visits.
The one rule
Never change a dose, skip a step, or accelerate a schedule on your own. The step schedule exists specifically to limit side effects, and moving through it faster is the most reliable way to make them worse.
If you think you are ready to move sooner, that is a good thing to raise — with the record in hand, it is a conversation rather than a request.
This guide is about keeping track of a plan. The plan itself, and every change to it, is your provider's decision.
