The signal is not the number on the pen, it is what is happening to you. Being unable to eat or drink adequately, symptoms that do not ease after a couple of weeks at a new dose, losing weight faster than intended, or side effects that stop you working or sleeping all suggest the dose has outpaced what you tolerate. That is a prescriber conversation, and it is a common one.
These are not too high a dose, they are urgent: severe abdominal pain, especially radiating to your back; vomiting you cannot stop or inability to keep fluids down; very little urine; confusion or fainting.
Do not reduce your own dose. Ask instead. Holding at your current step, going back down, or treating specific symptoms are all available, and all of them keep the dose accurate.
For how this fits into the wider titration picture, see GLP-1 Dosing and Titration: The Complete Guide.
The distinction that matters
Symptoms flaring in the days after a dose increase and then easing is the expected pattern. That is adaptation, not excess.
Symptoms that are still building two weeks into a new dose, or that never settle at all, are different information. So are symptoms arriving on a dose you have been stable on for weeks.

The practical signs
You cannot eat adequately. Not smaller portions, which is expected, but days where you manage almost nothing. Persistent inability to get protein and fluid in is the clearest sign.
You cannot drink enough. Dark or scant urine, dizziness on standing, or fluids sitting so heavily you avoid them.
Weight is falling faster than intended. Rapid loss costs muscle and raises gallstone risk, and it is a legitimate reason to slow down.
Life is being affected. Missing work, losing sleep, cancelling things. Prescribers weigh this differently from discomfort, so say it plainly.
Persistent vomiting or diarrhea. Never something to work around, because of where dehydration leads.
Signs You are Undereating on a GLP-1 Losing Weight Too Fast on a GLP-1 GLP-1s and Dehydration: Why It Happens
Signs pointing at intake rather than dose
Feeling cold constantly, hair shedding, exhaustion rest does not fix, losing strength, cycles becoming irregular.
These usually mean intake has fallen too low rather than that the dose itself is wrong, though the two are connected. Either way they are worth reporting, and the answer may be eating more rather than dosing less.

What to bring to the conversation
When the increase happened. What started and when. Whether it is improving or not. What you have actually eaten and drunk over a few days. What it is stopping you doing.
That last item carries the most weight, and people routinely leave it out because it feels like complaining.
What your prescriber can do
Hold you at the current dose rather than escalating. Step back to a previously tolerated dose. Treat specific symptoms. In some cases switch product.
Staying below the maximum dose long term is a legitimate outcome rather than a failure, and for many people a tolerated dose sustained beats a higher one abandoned.

The distinction that matters is timing, covered in whether side effects go away. Symptoms pointing at intake rather than dose are listed in the signs you are undereating, and the answer there is often eating more rather than dosing less.
Frequently asked questions
How do I know it is the dose and not just adjustment?
Adjustment eases within a week or two at a new dose. Symptoms still building after that are worth reporting.
Can I skip a dose to let it settle?
Not on your own judgement. Call and ask what to do about the next one.
Is fast weight loss a sign the dose is too high?
It can be, and it is a reason to raise it rather than to be pleased.
Will they take me off it entirely?
Unlikely as a first step. Holding or reducing usually comes first.
Does everyone reach the maximum dose?
No. Many people do well below it.
What if I am told to push through?
Ask specifically about holding the dose. If you are not being heard, a second opinion is reasonable.
