Serotonin-norepinephrine reuptake inhibitor (SNRI)
Venlafaxine 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 Venlafaxine (Venlafaxine) needs to be stopped before surgery, continued through, or paused for a defined window depends on Venlafaxine and the type of procedure.
Before-surgery decision
For most chronic medications including many Serotonin-norepinephrine reuptake inhibitor (SNRI) 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 Venlafaxine at 37.5mg, 75mg, 150mg on the pre-op form.
After surgery
Post-operative resumption of Venlafaxine 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. Venlafaxine inhibits the reuptake of both serotonin and norepinephrine at the synapse, with a dose-dependent profile: at low doses (≤75mg) it acts mainly on serotonin like an SSRI, while at higher dos… Resuming on schedule is usually the goal as soon as oral intake and clinical stability allow.
Frequently asked questions
Do I need to stop Venlafaxine before surgery? ▾

When can I restart Venlafaxine after surgery? ▾
Resumption timing depends on the procedure, the recovery course and any interactions with new postoperative medications. Many patients restart Venlafaxine on the day of discharge or earlier; some need a longer pause. The surgical team or prescriber confirms the timing.
