Selective serotonin reuptake inhibitor (SSRI)
Fluoxetine and surgery: what to do before and after
Surgery raises specific medication-management questions, and getting the answer right matters because both unintended drug interactions during anaesthesia and abrupt discontinuation of important chronic therapies carry risk. Whether Fluoxetine (Fluoxetine) needs to be stopped before surgery, continued through, or paused for a defined window depends on Fluoxetine and the type of procedure.
Before-surgery decision
For most chronic medications including many Selective serotonin reuptake inhibitor (SSRI) agents, the surgical team or anaesthetist makes the stop-or-continue decision during pre-op assessment. Considerations include bleeding risk, anaesthesia interactions, the urgency of the underlying condition and the type of procedure. According to most guidelines, surprises are avoided by listing all medications including Fluoxetine at 10mg, 20mg, 40mg on the pre-op form.
After surgery
Post-operative resumption of Fluoxetine depends on the surgical course, the medication's impact on recovery (e.g. wound healing, gastric tolerance, mobility) and any new prescriptions added after surgery. Fluoxetine selectively inhibits the serotonin reuptake transporter, increasing synaptic serotonin availability. Resuming on schedule is usually the goal as soon as oral intake and clinical stability allow.
Frequently asked questions
Do I need to stop Fluoxetine before surgery? ▾
It depends on Fluoxetine and the procedure. The pre-op assessment is where this is decided, ideally a week or more before surgery. Bring the full medication list including Fluoxetine at 10mg, 20mg, 40mg so the team can advise.
When can I restart Fluoxetine after surgery? ▾
Resumption timing depends on the procedure, the recovery course and any interactions with new postoperative medications. Many patients restart Fluoxetine on the day of discharge or earlier; some need a longer pause. The surgical team or prescriber confirms the timing.
