Trazodone Before Surgery: Confirm the Plan Instead of Counting Hold Days
There is no universal rule to stop trazodone seven days before surgery. Published clinical guidance often supports continuing it, but your own surgery, anesthesia, and prescribing teams’ instructions take priority. If you have a written instruction to hold trazodone, do not replace it with a website’s general recommendation to continue.
Confirm what your team wants you to do with your particular prescription for this procedure. Confirm that plan before changing your routine, including when instructions are missing or appear to conflict.
What the guidance actually says
The UKCPA Handbook gives trazodone-specific advice to continue for elective and emergency surgery. It also identifies interaction and withdrawal concerns.[1] A broader SPAQI consensus statement says most psychiatric medicines are continued, with some individual adjustments; its abstract is not a trazodone-specific dosing schedule.[2]
| Source | What it actually says | What requires your team’s decision |
|---|---|---|
| UKCPA trazodone handbook | Continue for elective and emergency surgery; assess relevant interactions.[1] | How that advice fits your operation and medicines. |
| SPAQI psychiatric-medication consensus abstract | Most psychiatric medicines are continued; some need case-specific adjustment.[2] | Whether an adjustment applies to your prescription. |
| U.S. trazodone prescribing information | Describes adverse effects, interactions, and discontinuation precautions—not a universal surgical hold.[3] | Whether your risks require a change and how to manage it. |
UKCPA provides UK clinical guidance; SPAQI provides broader expert consensus. Neither substitutes for instructions based on your procedure and prescription.
Bring enough information to get a usable answer
Give the team the exact medicine name and formulation, dose, frequency, reason you take it, and time of your last dose. Include other prescriptions, nonprescription medicines, and supplements. Explain what procedure you are having, the expected anesthesia, and any instructions already received.
Do not assume that a medication list alone answers the timing question. Ask specifically about fasting and whether you will be able to swallow or absorb oral medicines afterward. These details help turn a general medication review into instructions you can actually follow.
Write down the answers to these specific questions:
| Question to record | Answer to request |
|---|---|
| Have you checked my exact trazodone prescription and other medicines? | Confirmation that the review used my current list. |
| What should I do with the dose before surgery? | The exact dose instruction, including how it fits fasting requirements. |
| If my instructions disagree, who will reconcile them? | A named contact and one updated written plan. |
| What is the plan after the procedure? | Instructions covering oral intake, any change, and whom to contact with questions. |
Keep the resulting plan with your preoperative paperwork. If a phone call changes it, request a written update rather than relying on two different versions.
Why medication review matters
Trazodone can add to sedating effects from anesthesia and opioids. UKCPA also highlights serotonin-related and QT-related interaction review.[1] The prescribing information warns about serotonin syndrome, QT prolongation, and orthostatic hypotension or fainting.[3] These concerns support preparation, not a single stop interval for everyone.
MAO inhibitors, including linezolid and intravenous methylene blue, have specific label restrictions and require clinician management.[3] They are not interchangeable with every medicine that warrants a routine anesthesia interaction review.
If the instructions are missing or conflicting
Contact the preoperative or anesthesia service and the trazodone prescriber. Ask them to reconcile the instructions before you change treatment. Do not devise your own taper, substitute a sleep medicine, choose a restart date, or cancel the procedure yourself. If you already took a dose that differs from your instructions, report the amount and time taken.
For an urgent procedure, tell the treating team about trazodone and your last dose promptly; do not invent a waiting period. If oral medication will be unavailable for a prolonged period, ask for a specific management plan.[1] New agitation, fever, tremor, or rigidity with a rapid pulse warrants prompt medical assessment, not self-diagnosis or home treatment.[3]
Frequently asked questions
How many days before surgery should I stop trazodone?
There is no universal seven-day rule. Guidance often supports continuing, but follow your individualized instructions. If none are available, ask your surgery, anesthesia, and prescribing teams to agree on a written plan.[1,2]
What happens if I forget to stop trazodone before surgery?
Tell the preoperative or anesthesia team your dose and when you took it. They decide whether the plan needs changing. Do not cancel surgery or create a new hold interval yourself.
Why does trazodone interact with anesthesia?
Sedating effects can add together. Some perioperative medicines also raise serotonin-related or heart-rhythm concerns, so the anesthesia team needs your complete medication list.[1]
Can I take my trazodone the night before surgery for sleep?
Only according to your individual plan. General continuation guidance does not override a written hold instruction. Ask specifically about your night-before dose and fasting instructions.
Is the hold window different for trazodone compared with SSRIs?
There is no standard trazodone-versus-SSRI hold calendar. Broad psychiatric-medication guidance supports continuation in many cases, but decisions depend on the exact medicine and clinical circumstances.[2]
What can I take for sleep during the trazodone hold period?
First confirm whether a hold is actually prescribed. If it is, ask the prescriber about sleep support. Do not add an over-the-counter sleep aid or substitute another prescription without approval.
When can I restart trazodone after surgery?
Get a specific postoperative instruction; there is no universal 24–48-hour restart rule. Ask how oral intake and postoperative medicines affect the plan, especially if you cannot take tablets.
Does the dose of trazodone change the hold window?
Dose belongs in the review, but it does not establish a universal hold interval. A low dose is not automatically risk-free, and a higher dose does not automatically require stopping.
Is there a risk of withdrawal if I stop trazodone before surgery?
Yes. Abrupt discontinuation can cause symptoms. The label recommends gradual reduction when possible, but any surgical adjustment should be planned by your clinicians—not a self-directed taper.[3]
What is mCPP and why does it matter for the surgery hold?
mCPP is an active metabolite. Label section 12.3 describes trazodone conversion through CYP3A4 in vitro. That pharmacology does not provide a clearance clock or a surgical hold schedule.[3]
Should I tell my surgeon or my anesthesiologist about trazodone?
Tell both, and include your prescriber when changes are being considered. Share your exact prescription, last dose, other medicines, and any existing hold instructions.
Can trazodone cause serotonin syndrome on its own?
Yes; the label reports this risk alone or with other serotonergic medicines. New agitation, fever, tremor, or rigidity with a rapid pulse needs prompt medical assessment.[3]
