The short answer
The sign the label names is severe stomach pain that will not go away, with or without nausea or vomiting, sometimes felt through to the back. If it happens, the Medication Guide says to stop the medicine and call your healthcare provider right away. It was rare in the trials.
What the label says
Pancreatitis is an inflammation of the pancreas. It has its own warning in the prescribing information (§5.2):
From the labelAcute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, including WEGOVY.
The same section describes the sign doctors watch for, and the instruction:
From the labelAfter initiation of WEGOVY, observe patients carefully for signs and symptoms of acute pancreatitis, which may include persistent or severe abdominal pain (sometimes radiating to the back), and which may or may not be accompanied by nausea or vomiting. If pancreatitis is suspected, discontinue WEGOVY and initiate appropriate management.
The Medication Guide says it to you directly:
From the labelStop using WEGOVY and call your healthcare provider right away if you have severe pain in your stomach area (abdomen) that will not go away, with or without nausea or vomiting. Sometimes you may feel the pain from your abdomen to your back.
How often it happened
The trial figures are in §6.1, in a group of reactions the label introduces this way:
From the labelThe below adverse reactions were reported in WEGOVY injection clinical trials and are applicable to both WEGOVY injection and WEGOVY tablets.
So the numbers below come from the injection trials in adults, and the label applies them to the tablet:
From the labelIn WEGOVY clinical trials in adults for weight reduction, acute pancreatitis was confirmed by adjudication in 4 WEGOVY-treated patients (0.2 cases per 100 patient years) and 1 in placebo-treated patients (less than 0.1 cases per 100 patient years).
"Confirmed by adjudication" means an independent committee reviewed each case. "Per 100 patient years" means about 0.2 cases for every 100 people followed for a year. Since approval, the label adds (§6.2), acute and necrotizing pancreatitis have been reported, sometimes resulting in death. Those reports are voluntary, so the label does not estimate how often they happen.
Telling it apart
Stomach symptoms are the most common side effects of this medicine: nausea, sore stomach, bloating. They come and go, and in the injection trials they were reported most often during dose escalation. What the label describes for pancreatitis is different in three ways: the pain is severe, it stays, and it can go through to the back. Vomiting may or may not come with it.
There is no home test. The label leaves the diagnosis to the clinician, and the Medication Guide's rule is short: if it sounds like that, stop and call. If you think it is an emergency, call your local emergency number.
Two other warnings sit next to this one and overlap in symptoms: gallbladder problems, with pain in the upper stomach, fever or yellowing of the skin or eyes, and dehydration from vomiting that does not stop. Both have their own pages.
Oolite's journal keeps the days a stomach symptom was there, so a pain that is lasting longer than usual shows as a run of days, ready for the call. It does not judge symptoms.
Questions people ask
How common is it?
Rare. In the adult trials, acute pancreatitis was confirmed in 4 people on the drug, 0.2 cases per 100 patient years, against 1 on placebo, under 0.1. These figures come from the injection trials, and the label applies them to the tablets too.
How is it different from ordinary stomach upset?
The label's words are persistent or severe abdominal pain, sometimes radiating to the back. Ordinary nausea or a sore stomach comes and goes. When you are not sure, the Medication Guide's answer is to call.
Do I stop the tablet if I suspect it?
Yes, that is what the Medication Guide says: stop using Wegovy and call your healthcare provider right away. The restart decision is the prescriber's.
I had pancreatitis years ago. Does that matter?
The Medication Guide asks you to tell your healthcare provider before using Wegovy if you have or have had problems with your pancreas. The decision is theirs to make with your history in front of them.
