This page covers the practical step to take if injections worry you: raise it at the consultation, before a first dose rather than after. Fainting around needles is worth telling the doctor about too.
What to do with this before you start
Say it at the consultation. That is the whole recommendation.
A concern about needles is a clinical conversation — it affects how a first dose is best approached, and it is exactly the kind of thing a doctor would rather know in advance. Raising it does not count against you, and it is not a reason to talk yourself out of an assessment.
If you would like to know what the injection itself involves before deciding, your first GLP-1 injection covers the shape of the first one and what the trials recorded about it. If you are wondering whether a tablet would avoid the question entirely, is there a GLP-1 that is not an injection gives the Singapore answer, which is more complicated than you might expect.
You can check your eligibility and speak to a doctor about whether this is suitable for you.
If what brought you here was a search for a tablet instead, the registered picture is in the tablet, and what it is for.
