Do I stop the Wegovy pill before surgery?
The label does not say to stop. It says the data are insufficient to recommend changing fasting rules or pausing the medicine before anesthesia or deep sedation. What it asks is that you tell every healthcare provider you take Wegovy before any planned surgery or procedure.

The short answer
The label does not say to stop. It says the data are insufficient to recommend changing fasting rules or pausing the medicine before anesthesia or deep sedation. What it asks is that you tell every healthcare provider you take Wegovy before any planned surgery or procedure.
What the label says
The warning is in §5.10 of the prescribing information, under the title Pulmonary Aspiration During General Anesthesia or Deep Sedation. It starts with the mechanism and the reports:
From the labelThere have been rare postmarketing reports of pulmonary aspiration in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation who had residual gastric contents despite reported adherence to preoperative fasting recommendations.
Pulmonary aspiration means stomach contents going into the lungs. The point of the sentence is that these people had fasted as told, and their stomach was still not empty.
Then comes the line that answers the question most people ask:
From the labelAvailable data are insufficient to inform recommendations to mitigate the risk of pulmonary aspiration during general anesthesia or deep sedation in patients taking WEGOVY, including whether modifying preoperative fasting recommendations or temporarily discontinuing WEGOVY could reduce the incidence of retained gastric contents.
The section ends with what it asks for:
From the labelInstruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking WEGOVY.
The Medication Guide puts it in the patient's words:
From the labelTell all your healthcare providers that you are taking WEGOVY before you are scheduled to have surgery or other procedures.
What "insufficient data" means for you
It means the label does not give a rule. It does not say to stop the tablet, and it does not say that stopping is useless. It says no one has shown which approach reduces the risk. So the plan is made case by case, by the people who know the procedure and your history.
One fact from the label is useful in that conversation. Semaglutide leaves slowly: the pharmacokinetics section (§12.3) says it remains in the circulation for about 5 to 7 weeks after the last 25 mg tablet. A pause of a day or two does not empty the body of it. That is for the team to weigh, not a reason to act alone.
When to say it
Twice, according to the Medication Guide. First when the medicine is started: it asks you to tell your provider before using Wegovy if you are scheduled for surgery or a procedure that uses anesthesia or deep sedation. Then before every procedure that comes up later, to every provider involved.
Useful things to have with you: the name of the medicine and its form (the daily tablet), the dose step you are on, the date you started that step, any recent nausea, vomiting or a feeling of fullness, and the name of the prescriber.
If the advice you get means pausing the tablet, ask about the restart at the same time. The label gives no restart rule for the tablet after a pause, so the step you come back on is the prescriber's call.
Oolite keeps the dose step and the date you started it, and the report for the prescriber puts both on one page you can hand to the surgical team.
Questions people ask
Why does a tablet for this matter to the anesthesia team?
Because semaglutide slows stomach emptying. The label reports rare cases of food remaining in the stomach despite fasting, and of it reaching the lungs during anesthesia or deep sedation.
Should I stop a week before, to be safe?
The label says available data do not show whether temporarily stopping would reduce the risk. Whether to pause, and for how long, is a decision for your prescriber and the team doing the procedure.
Who counts as a healthcare provider here?
The Medication Guide says all of them. In practice: the surgeon or doctor doing the procedure, the anesthesia team, and the prescriber of the Wegovy pill, so they can agree on a plan.
What about the morning of the procedure?
Ask specifically. The tablet is taken on an empty stomach with water, and the team's fasting instructions for that morning are theirs to set. The label does not settle it.
