How to Record a GLP-1 Dose Change Your Prescriber Made

This page is about one narrow thing: what to write down when your prescriber changes your dose. It is not about when a dose should change, what the next step is, or whether you are ready for one. Those decisions belong to the person who prescribed the medication, they are individual, and no tracking app or web page should have a view.

That boundary matters more here than almost anywhere else in tracking, because a dose schedule copied from a web page is not a plan made for you, and following one could do real harm. What a page can usefully cover is the record-keeping, and that is where things go wrong: a dose change is the point at which most people's logs quietly break.

They break because a change is three separate edits — the instruction, the schedule, the reminder — and people make one of the three. Two months later the log says one thing, the pharmacy label says another, and the reminder is still firing on the old plan. The procedure below is mostly about doing all three at once.

Before you change anything in your log, transcribe the new instruction exactly: the medication, the new strength with its units, and the schedule, copied from the pharmacy label or the written note you were given.

Do this even if the change seems simple and obvious. A change described from memory the following week is the same category of error as a first dose recorded from memory, and it has the same consequence — a record that disagrees with the prescription without anybody noticing.

Keep the old instruction too, with the date it stopped applying. A log that only ever shows the current instruction cannot tell you what you were on in April, which is precisely the question that comes up when you are trying to interpret April.

If the label and what you were told differ in any way, that discrepancy goes to your pharmacist or prescriber the same day. Do not decide which one is right and record that.

The change starts on the day you first take the new dose. Record that date, not the date of the appointment where it was agreed.

These are routinely a week or more apart, and the difference is not cosmetic. If you date the change from the appointment, every dose taken in between gets attributed to the new level, and any later attempt to compare how you felt before and after is reading a boundary that is in the wrong place.

If you are unsure exactly which dose was the first at the new level, look at your own log for the answer rather than estimating — this is one of the things a dose log is uniquely good at. If the log does not have it, record your best estimate and mark it as approximate.

Leave every earlier entry exactly as it is, on the dose it was actually taken at.

The urge to tidy is understandable and completely wrong. Your history is the only comparison you have: the whole point of knowing that something changed on a particular date is being able to read the weeks either side of it. Overwriting the old dose so the log looks internally consistent deletes the before, and after that the change is unreadable.

Good tools make this the default. In GLP-1 Tracker, changing your medication or dose affects future entries only, and past shots stay attached to what they were logged with — the app says so explicitly when you make the change. On paper, the equivalent discipline is that you draw a line and start a new section rather than going back with an eraser.

The only edits worth making to old entries are genuine mis-entries: a typo, a wrong date. Correct those, and leave everything else.

In the same sitting, change three things: the dose on your recurring schedule, the reminder, and anything that autocompletes a dose value for you.

Missing the reminder is the classic failure. The dose changes, the alert keeps firing on the old plan, and if your reminder also pre-fills a dose you end up logging the old value for weeks. That produces a log that is wrong in the most damaging possible way — internally consistent, plausible, and describing a routine you are not on.

If the schedule itself changed as well as the strength — a different day, a different frequency — change it once, deliberately, to what you were actually told. And if you are unsure what you were told about spacing, ask before you edit. That is a pharmacist question, not a settings question.

Some prescribed doses do not appear in an app's built-in list, particularly where a prescription is individualised. Enter the exact value rather than rounding to the nearest option offered.

Rounding is tempting because it takes one tap and it looks close enough. It is not close enough: the rounded number is what every later summary, chart and export will report, including anything you hand to a clinician, and nobody downstream will know it was approximated.

Most tools have a way to enter an arbitrary value. GLP-1 Tracker lets you add and manage custom doses, which then appear alongside the standard options. If yours does not, write the true value in the entry's note field and treat the selected option as a label rather than a measurement — but prefer a tool that lets you be accurate.

Put a dated marker on your other records too, so the change is visible when you are reading those rather than your dose log.

A one-line note against that week — "dose changed on the 14th" — is enough. Without it, a shift in how you felt or a bump in your weight trend a fortnight later has no visible cause on the chart you are looking at, and you will either forget the change happened or reconstruct the date wrongly.

This is the annotation that makes a summary readable months later. "Symptoms increased in late April" invites speculation; "symptoms increased in late April, two weeks after the dose change on the 14th" is a specific observation that a clinician can do something with. Note the association, and let them decide what, if anything, it means.

Treat the period after a change as a distinct block rather than continuing to read your whole history as one continuous run.

Practically: when you next look at your trend or your symptom counts, set the window to start at the change date and compare that block against the equivalent block before it. This is a far more informative comparison than an all-time chart, in which a change of dose is a detail lost in the middle.

Give it about four weeks before reading much into it, for the same reason a weight trend needs four weeks: below that you are looking at noise. And keep the comparison descriptive. You are noting what your record shows across a change, not evaluating whether the change was correct — that judgement is your prescriber's, and it is informed by a great deal that is not in your log.

A well-kept dose-change record tells you and your clinician exactly what you were taking, from when, and what your own data looked like either side of it. That is genuinely useful and it is the whole of it.

It cannot tell you whether a change was right, whether the next one is due, or how you should respond to how you feel afterwards. GLP-1 Tracker holds no dosing logic of any kind: it records the schedule you enter, and while it can draw a projected line forward, that line is an illustration of the schedule you gave it, not a recommendation. It will never propose a change.

If something after a dose change is severe, getting worse, or worrying you, that is a reason to contact your provider now — not a reason to gather four weeks of data first.
