This list is short and it is not the same as the common list. These are the symptoms where the correct response is to stop the medication and be seen the same day, rather than to adjust how you eat and wait it out.
Severe abdominal pain, particularly pain that is persistent or radiates through to the back, is the one to know. It can indicate pancreatitis and it is not a symptom to manage at home.
Repeated vomiting where you cannot keep fluids down is the second, both in its own right and because of dehydration. Pain in the upper right abdomen, fever, or yellowing of the skin or eyes point toward the gallbladder.
Signs of a severe allergic reaction, and in people also taking insulin or a sulfonylurea, symptoms of very low blood sugar, complete the list. None of these are common. All of them are worth knowing before you start. There is more in Common side effects, Who should not take it and Drug interactions.
Know these
What to do
If a red flag appears
Stop the medication
Do not take the next dose. This is one of the few situations where stopping first and asking afterwards is correct.
Get seen the same day
Urgent care or an emergency department depending on severity. Not the next scheduled review.
Say what you are taking
Name the medication and the dose. It changes what whoever sees you will consider first.
Tell your clinician
Once you are safe. Whether treatment restarts, and how, is a decision made afterwards with the full picture.
Context
These are uncommon, and worth knowing anyway
Pancreatitis and gallbladder problems are uncommon on these medications, and rapid weight loss from any cause raises gallbladder risk somewhat regardless of how it is achieved.
Knowing the list is not about expecting it to happen. It is so that you recognise the difference between the discomfort that is part of the first weeks and the pain that is not, without having to work it out at eleven at night. GLP-1 and type 2 diabetes covers the next part, alongside Physician-supervised care and Nausea and digestion.
What counts as urgent, how likely it is, and what happens afterwards.
Severe or persistent abdominal pain, especially radiating to the back; repeated vomiting where you cannot keep fluids down; upper right abdominal pain with fever or yellowing skin; and signs of a severe allergic reaction.
Uncommon. Knowing the list is about being able to tell the difference quickly, not about expecting it to happen to you.
For these specific symptoms, yes. Do not take the next dose, then get seen. For anything on the common list, report it and wait for advice instead.
Sometimes, depending on what happened and what was found. That decision is made afterwards with the full picture, and often involves a different molecule or a slower schedule.
Rapid weight loss from any cause raises gallbladder risk somewhat, which is one reason a steady rate is preferred over the fastest possible one.
