Treatment stops for all sorts of reasons. Supply runs short, a prescription lapses, cost gets in the way, side effects need a pause, an unrelated illness or an operation intervenes, or a clinician plans a break on purpose. Whatever the reason, restarting is arranged by a prescriber and not decided at home. GOV.UK is unambiguous that these are prescription-only medicines used under professional supervision, and NHS England describes weight management injections as something provided inside a supervised pathway rather than picked up independently. If you are wondering whether to resume, that is a conversation, not a page.
This article assumes the conversation has happened and the arrangement is made. What follows is about the records, which after a break are usually in worse shape than people realise.
Write down the gap before you write anything else
The break is itself a piece of information, and it is the piece most likely to be lost. Six weeks from now the details will have blurred into a general sense that you were off it for a while, which is not much use to anyone. Ten minutes spent on this before you resume is worth more than the next three months of diligent logging.
- The date of your last dose before the break, as precisely as you can establish it
- The date treatment resumed, once it does
- Why the break happened, in one plain sentence
- What happened to your weight across it, from any readings you have, even irregular ones
- What happened to your appetite and eating during the gap, which is often the most striking part and the least recorded
- Whether any symptom you had been having resolved while you were off, and roughly when
That last point is quietly valuable. A symptom that disappeared during a break and returns after resuming tells a clinician something a symptom recorded in isolation never could.
Set a new baseline instead of reaching back
The temptation is to pick up the old series where it left off, as though the gap were a page that fell out. Resist it. Your starting point now is where you actually are today, not where you were before the break, and comparing the coming weeks against a figure from several months ago will mislead you in whichever direction it happens to point.
So take a fresh baseline: weight on a named date, measurements if you keep them, a photograph if that is part of what you do, and a short honest paragraph on how you feel at the moment of resuming. CDC guidance on weight management recommends tracking progress with consistent methods, and consistency is exactly what a break disrupts, so re-establishing the method matters as much as re-establishing the number. Keep the old series in your records, clearly marked and closed; you can look at both, and neither pretends to be continuous with the other.
Do not carry your old tolerance forward
This is the single most important thing on the page. Whatever you had got used to before the break is not a guide to what happens now. People often assume that because they had settled into a comfortable pattern previously, they will land straight back into it, and then find the early weeks harder than expected and put off saying so.
MedlinePlus notes that these medicines affect appetite, fullness and digestion, and both NHS guidance on semaglutide and MedlinePlus information on tirzepatide describe digestive effects among those reported. MHRA continues to remind patients and clinicians to stay alert to what this class of medicines can do. None of that changes because you have taken the medicine before. Treat the first weeks after resuming as new territory and record them accordingly, rather than skipping notes on the grounds that you already know how this goes.
The first month back
Keep it close for four weeks or so, then ease off to whatever cadence you can actually sustain. What to capture is unremarkable and that is the point.
- The date of each dose, written down at the time
- Any symptom, when it began relative to the dose, how long it lasted, and whether it kept you from doing something
- What you were able to eat on the harder days, and whether you were drinking enough
- Energy and sleep, in a word or two, not a score
- Anything you want to ask, captured the moment it occurs to you
Add one line that no ordinary tracking month needs: how this compares to what you remember of before the break. Not as a judgement, just as an observation. It is the question a prescriber is most likely to ask at the next review and the one hardest to answer from memory.
Supply, storage and stale paperwork
A break leaves administrative debris. If you have any medicine left over from before, do not make assumptions about whether it is still usable; ask a pharmacist, who can check the storage conditions and dates against what actually happened to it. That is a question with a real answer and it is not one to guess at.
Your medicines list will also have gone out of date, particularly if anything else changed during the gap. FDA recommends keeping such a list current and bringing it to appointments, and the weeks after a restart are precisely when several clinicians may be working from different versions of your history. Note down, too, whatever practical arrangements were made for the resumption, including who to contact if something goes wrong, so that information is not sitting in a message you will struggle to find.
Where the page ends
Nothing here describes how treatment is resumed, at what level, or on what timetable, because that is a prescribing matter and the answer is specific to you. If you still have medicine at home and have been told to wait, wait. NHS guidance on semaglutide and the leaflet inside your own pack both direct questions about how a medicine is taken to a doctor or pharmacist, and after a break those questions are more common rather than less.
Get urgent medical help for severe abdominal pain, persistent vomiting, an inability to keep fluids down, or signs of a serious allergic reaction such as swelling of the face or difficulty breathing. Everything else on this page can wait for a review appointment; those cannot.
