GLP-1s before surgery or dental sedation

Tell the procedure team early

If you take a GLP-1, tell the team arranging your surgery or procedure before the appointment. This includes a medication used for diabetes, weight management, or another reason. The relevant question is whether you will receive general anesthesia or deep sedation, not whether you consider the appointment major surgery. The American Society of Anesthesiologists advises discussing these medicines with the anesthesiologist, surgeon and prescriber together.¹

A dental appointment can mean a cleaning with no sedation, local numbing, or deeper sedation. Ask which is planned. Do not assume that a dental office already knows about a prescription from an online clinic. A short message now is more useful than trying to explain your treatment while checking in with a driver waiting outside.

Why the stomach matters

GLP-1 medicines can slow stomach emptying. During general anesthesia or deep sedation, stomach contents can enter the lungs; this is called aspiration. Current Wegovy and Zepbound labels include warnings about reported aspiration in people having these procedures.^2,3 This warning explains why your medication belongs on the pre-procedure checklist. It does not mean that every person taking a GLP-1 has a full stomach or will have a complication.

Fasting instructions still matter. However, following the usual instructions does not settle every GLP-1 question. The procedure team needs to consider the medicine, your symptoms, your stage of treatment and the planned anesthesia. Tell them about nausea, vomiting, constipation or abdominal pain instead of treating those details as unrelated to the appointment.¹

Is everyone supposed to stop?

No. ASA's current patient guidance says most patients can continue their medicine before a procedure. Some need a different plan, particularly during dose escalation or when digestive symptoms are present. The team may discuss a liquid-only diet, stomach ultrasound, a change in anesthesia precautions, or postponement.¹ These are decisions for the team responsible for your procedure, not a menu to choose from yourself.

An old instruction found through a search may conflict with the facility's current plan. Send both instructions to the team and ask them to resolve the difference in writing. Do not combine a fasting schedule from one hospital with a medication schedule from another. If the drug treats diabetes, ask who will manage glucose if treatment changes.

A message you can copy

Try: “I take [exact medication and formulation] at [prescribed dose]. My last dose was [date and time]. My procedure is [name and date]. Will I have general anesthesia or deep sedation? Please confirm the medication and fasting plan with my prescriber.”

Add whether your dose recently changed and whether you have digestive symptoms. List other medicines and supplements as well. A photo of the prescription label can help distinguish a branded pen, a tablet and a compounded vial. You do not need to interpret the label yourself to share it accurately.

Ask for one named contact if the clinic, surgeon and anesthesia office give different answers. Write down who will confirm the plan and when. If the appointment is tomorrow and nobody has answered, contact the procedure team directly rather than guessing about your next dose.

Plan for the day after, too

Before the procedure, ask who will tell you when to resume treatment, what to do if you cannot eat normally, and whom to call about persistent vomiting. A temporary interruption can create a separate restart question. Our missed-dose and restart guide explains why the original product matters.

In an emergency, do not delay needed care to meet a medication schedule. Tell the emergency and anesthesia teams what you took and when. Keep the medication details accessible on your phone or with the person accompanying you.
