Duloxetine (Cymbalta) withdrawal
Here is what the FDA-approved label for Duloxetine (Cymbalta) actually says about stopping it — not a secondhand summary. The single most important point applies to every drug on this list: don’t stop abruptly on your own.
What the label says about stopping Duloxetine
The label has a section titled Discontinuation Syndrome. It reports that after abrupt or tapered discontinuation in trials, symptoms occurring more often with duloxetine than placebo included dizziness, headache, nausea, diarrhea, paresthesia, irritability, vomiting, insomnia, anxiety, hyperhidrosis, and fatigue. It further cites spontaneous reports across SSRIs/SNRIs of dysphoric mood, agitation, sensory disturbances such as electric-shock sensations (paresthesias), confusion, emotional lability, hypomania, tinnitus, and seizures on discontinuation, particularly when abrupt; some have been severe. The label directs that a gradual, prescriber-managed dose reduction rather than abrupt cessation is recommended whenever possible, and that if intolerable symptoms occur the prescriber may consider resuming the previous dose and then tapering more slowly. This is not in the boxed warning (the boxed warning concerns suicidal thoughts and behaviors).
Why the taper matters
After your body adapts to a drug taken regularly, removing it too fast forces an abrupt readjustment — that is what withdrawal (also called discontinuation) is. A prescriber-managed taper steps the dose down gradually so the adjustment is gentle, and it can be slowed if a step is hard. This is why the fix is never to “push through” a cold-turkey stop, and never to piece a schedule together from a forum. Talk to the prescriber who manages your dose before you change anything.
And alcohol with Duloxetine?
The label warns about alcohol, but the mechanism is liver injury, not a disulfiram reaction or sedation. It states that using duloxetine concomitantly with heavy alcohol intake may be associated with severe liver injury, and that duloxetine should not be prescribed to patients with substantial alcohol use or evidence of chronic liver disease. The patient information explicitly advises avoiding heavy alcohol use while taking the drug. Notably, the label adds that in interaction studies duloxetine did NOT increase the impairment of mental and motor skills caused by alcohol, so the concern is hepatic, not additive CNS impairment.
Frequently asked questions
Can I stop Duloxetine suddenly?
Not on your own. Duloxetine's FDA label describes a discontinuation or withdrawal issue (summarized above), and stopping abruptly after regular use can bring it on. The safe route is a gradual, prescriber-managed taper — a cold-turkey stop decided alone is exactly what the label warns against.
How long does Duloxetine withdrawal last?
There is no single answer and the FDA label does not set a fixed timeline. In general it depends on the drug's half-life, your dose, and how long you took it — and a slow, prescriber-guided taper is what shortens and softens it. Ask the prescriber who manages your dose to map a schedule to your situation.
How do you safely taper off Duloxetine?
Tapering means lowering the dose in steps over weeks so your body adjusts, under the prescriber who knows your history. If a step is too hard, the schedule can be slowed — that flexibility is the point. Do not design a taper yourself from an internet schedule, and do not use alcohol or other sedatives to cope with symptoms.
If you are having a medical emergency — or thoughts of harming yourself while stopping a medication — call 911, or call or text 988 (the US Suicide & Crisis Lifeline).

The description of stopping this drug is transcribed from its FDA-approved label; the taper guidance is general and true of these medicines as a class. This is reference information, not medical advice, and not a taper schedule — do not start, stop, or change a dose based on it. Any change should be planned with your prescriber.
