Key takeaways The FDA label says people on 300 mg of Wellbutrin XL should drop to 150 mg before stopping, and MedlinePlus says not to stop without talking to your doctor. In 100 r/bupropion threads, most people who said how they stopped had quit all at once. Tiredness, anxiety, nausea, poor sleep and headaches were the symptoms people named most; brain zaps, the brief electric jolts typical of SSRI withdrawal, were rare. Most people in our threads stopped all at once, while the label asks for a step down first; plan any stop with your prescriber. On this page
What 149 people on r/bupropion said about stopping Wellbutrin What are the symptoms of Wellbutrin withdrawal? How long does Wellbutrin withdrawal last? Why is Wellbutrin withdrawal different from SSRI withdrawal? Is it withdrawal or is depression coming back? What should you tell your prescriber before stopping Wellbutrin? Wellbutrin (bupropion) withdrawal does happen, though it tends to look different from SSRI withdrawal. The FDA label says that people on 300 mg of Wellbutrin XL a day should drop to 150 mg before stopping. MedlinePlus says not to stop bupropion without talking to your doctor, who may lower the dose gradually.
What 149 people on r/bupropion said about stopping Wellbutrin
We read 100 recent threads about stopping Wellbutrin on r/bupropion, comments included, and 149 people described their own experience of stopping or cutting down. These are people's own accounts online, not a clinical study, and people with a hard time are more likely to post, so treat this as a range of experiences rather than odds.
Most who said how they stopped had quit all at once: 42 of 52, against 10 who lowered the dose gradually. Of the 74 who said where they ended up, 21 were off and doing fine, 21 were off but still struggling, 20 went back on and 12 were still cutting down.
What are the symptoms of Wellbutrin withdrawal?
Tiredness was the symptom people named most, then anxiety, nausea, poor sleep and headaches. Of the 149 people, 73 wrote about symptoms, and 24 of those said they had none or barely any. One person can be in more than one row:
Symptom people named Of 149 people None, or barely any 24 Tiredness 17 Anxiety or panic 11 Nausea or flu-like feeling 11 Sleep problems or vivid dreams 11 Headache 10 Irritability or anger 8
One person on r/bupropion described their taper:
it was mostly a sense of fatigue and overall lower energy and being more irritable
How long does Wellbutrin withdrawal last?
Neither the FDA label nor MedlinePlus gives a length for bupropion withdrawal. Of 33 people on r/bupropion who said how long symptoms lasted, the typical answer was 2 weeks, though a few named months. If symptoms are still strong after two weeks, or keep growing, that is worth a call to your prescriber.
Why is Wellbutrin withdrawal different from SSRI withdrawal?
Bupropion works on different brain chemicals. The label says its mechanism is unknown; it is a relatively weak inhibitor of the reuptake of norepinephrine and dopamine and does not affect the reuptake of serotonin at all. That fits the symptoms people link with SSRI withdrawal, such as brain zaps, being less typical. In the r/bupropion threads, only one person named brain zaps. Tiredness and low energy were named most, and the reason is not well studied.
Is it withdrawal or is depression coming back? Medically reviewed by Dr. Jason Tan on October 27, 2026, this section only.
Withdrawal and a return of depression can look alike, and the difference changes what you do next. Timing is the first clue: withdrawal tends to start within days of a cut, while a relapse builds over weeks. On bupropion, the physical side of withdrawal more often shows up as tiredness, nausea or headaches than as brain zaps, and tiredness is also a sign of depression, so note when it started and whether mood and interest changed with it. The clinical view:
For many people symptoms are mild and pass within a couple of weeks. For others they are severe or last for months, and there is no reliable way to know in advance, although longer use, higher doses, medications that leave the body quickly and withdrawal on a past attempt all raise the risk. Stopping all at once carries the highest risk.
Withdrawal tends to start within days of a cut (later with fluoxetine) and includes physical symptoms, like brain zaps. It often eases soon after the previous dose is restarted. A relapse usually builds more slowly, over weeks.
If symptoms during a reduction are hard to bear, talk to your prescriber. The usual step is to go back to the last dose that felt stable, then reduce more slowly. Some changes need a call the same day, not at the next appointment: mood dropping fast, feeling hopeless, or thoughts of harming yourself. If you have those thoughts, contact emergency services or a crisis line straight away. In the US, call or text 988. In the UK, call Samaritans on 116 123. Elsewhere, find a crisis line near you .
What should you tell your prescriber before stopping Wellbutrin?
Plan the stop with your prescriber before you cut a dose, including what to do if symptoms come. If you have already stopped, tell them now: when you stopped, from what dose, and what you have felt each day since. It helps to tell them:
Why you want to stop, and how long you have been on Wellbutrin. Your current dose and form, XL or SR. Whether you have had withdrawal or a relapse before. Other medications you take, including other antidepressants. Big events coming up, such as exams, travel or a new job. For antidepressants in general, not bupropion specifically, the Royal College of Psychiatrists says withdrawal symptoms can usually be kept down by reducing the dose slowly over a few weeks, and that some people need to restart and reduce even more slowly.

Frequently asked questions Can you stop Wellbutrin cold turkey? Most people in our threads who stopped did so all at once. The label asks people on 300 mg of XL to drop to 150 mg first. If you have already stopped suddenly and feel unwell, tell your prescriber what you feel and since when.
Can I go back on Wellbutrin after stopping? Some people do: in our count, 20 of 74 went back on. If you are thinking about it, tell your prescriber when you stopped, what dose you were on and how you have felt since.
Does Wellbutrin withdrawal cause brain zaps? It's less typical than with SSRIs; only one person in our threads named them. If you get them, note when they started relative to your last dose and tell your prescriber.
Why am I so tired after stopping Wellbutrin? Tiredness was the symptom people on r/bupropion named most after stopping. It can also be depression returning, so keep a daily note of energy, mood and sleep and share it with your prescriber.
