Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant
Bupropion withdrawal — symptoms and tapering
Withdrawal from Bupropion (Bupropion) — used for Bupropion is approved for major depressive disorder, prevention of seasonal affective disorder recurrence, and smoking cessation. — is the body's response to the absence of a medication after physiological adaptation has developed. It is distinct from disease relapse: withdrawal usually appears within hours to days of dose reduction or stopping, follows a predictable pattern related to Bupropion pharmacology, and resolves over a defined timeframe. Below is a focused look at typical withdrawal from Bupropion at the 75mg, 100mg, 150mg, 300mg dosing strengths and the principles of safe discontinuation.
Typical withdrawal pattern for Bupropion
Withdrawal symptoms after stopping Bupropion depend on the half-life of Bupropion, the dose at the 75mg, 100mg, 150mg, 300mg range, duration of use and individual physiology. Common rebound features in the Norepinephrine-dopamine reuptake inhibitor (NDRI) antidepressant class include the original symptoms returning more intensely, sleep disturbance, anxiety, irritability, gastrointestinal upset, headache, sensory disturbances and, in some classes, rare but serious events such as seizures. Onset is usually within 1–3 days for short-half-life drugs and 5–10 days for long-half-life ones; total duration ranges from one to several weeks.
Tapering principles and when to seek medical help
According to general clinical guidance, discontinuing Bupropion after sustained use is best done by gradual taper rather than abrupt cessation. Typical schedules reduce the 75mg, 100mg, 150mg, 300mg dose by 10–25% every one to four weeks, slower at lower doses. Substituting a long-half-life equivalent within the same class can smooth the transition. Severe withdrawal — seizures, marked autonomic instability, suicidal ideation, severe insomnia or persistent vomiting — requires medical evaluation; emergency care is appropriate for any acute neurological event.
Frequently asked questions
How long do Bupropion withdrawal symptoms last? ▾
Most withdrawal symptoms after stopping Bupropion resolve within one to four weeks, with peak intensity in the first one to two weeks and tapering thereafter. Long-half-life formulations of Bupropion produce later, gentler onset; short-half-life formulations produce earlier, sharper symptoms. Protracted symptoms — beyond six to eight weeks — can occur with some classes after long-term use and warrant clinician input.
Can I stop Bupropion cold turkey? ▾

According to typical prescribing information, the safest path is a gradual reduction guided by the prescriber, often over weeks to months. If you have already stopped abruptly and feel unwell, contact your prescriber promptly; severe symptoms warrant urgent care.
