How Long Does Bupropion Withdrawal Last? Full Timeline & Recovery Guide

Bupropion, commonly known by brand names like Wellbutrin or Zyban, is a prescribed antidepressant used to treat major depressive disorder (MDD) and to help prevent seasonal affective disorder (SAD), as noted by the Mayo Clinic. While it can be very effective, discontinuing bupropion, particularly if done suddenly, may result in withdrawal symptoms that can be quite uncomfortable. Gaining a thorough understanding of the bupropion withdrawal timeline can significantly alleviate anxiety about the process and empower individuals to better manage their symptoms.
Withdrawal symptoms from bupropion can differ in severity and duration, influenced by factors such as dosage, the length of time the medication was used, and individual brain chemistry. These symptoms may persist for several weeks or even months in some instances, but there are effective strategies to alleviate discomfort. Whether you are considering a gradual reduction with medical support or are currently experiencing withdrawal, being informed about the complete timeline and recovery options will help you approach the journey ahead with assurance and support.
What is Bupropion (Wellbutrin)?
Bupropion is in a class of medications called norepinephrine-dopamine reuptake inhibitors (NDRIs), which work by increasing certain types of activity in the brain. It is used to treat depression, seasonal affective depression that occurs at the same time each year, usually in the fall and winter, and to aid in smoking cessation. According to MedlinePlus, Bupropion is also occasionally utilized to manage depressive episodes in individuals with bipolar disorder and to address attention deficit hyperactivity disorder (ADHD).
This medication primarily influences the brain’s norepinephrine and dopamine levels, which are believed to play a crucial role in mood control and addiction. It may provide stimulating effects that can help those experiencing low energy or fatigue associated with depression, as well as individuals with ADHD.
Users of Bupropion have reported experiencing fewer side effects compared to selective serotonin reuptake inhibitors (SSRIs) like Prozac and Zoloft. Nonetheless, some may still encounter side effects such as dry mouth, insomnia, headaches, nausea, sweating, and increased heart rate. There is also a potential risk of seizures for certain individuals, particularly at higher doses or among those with specific risk factors like eating disorders and alcohol consumption.
Bupropion is not typically the first choice for treating depression; doctors often recommend it when SSRIs or SNRIs lead to intolerable side effects or prove ineffective. Patients can generally expect to see improvements within the first or second week, with maximum effectiveness usually reached after about two months of treatment.

Can You Experience Withdrawal from Bupropion?
When taking Bupropion, individuals will develop a dependence to the medication. While this may sound concerning, it does not mean you are addicted; rather, it’s a natural response of the body to the medication’s presence. Bupropion influences the levels of dopamine and norepinephrine, which are neurotransmitters associated with mood, energy, motivation, and reward. As time passes, the brain may become accustomed to the medication and depend on it to regulate these neurotransmitters. If Bupropion is suddenly discontinued, the brain might temporarily find it challenging to balance these chemicals independently, resulting in withdrawal symptoms.
While withdrawal from Bupropion is possible, it is typically less frequent and less intense compared to withdrawal from other antidepressants or substances like benzodiazepines or opioids. Stopping Bupropion abruptly may not trigger classic physical withdrawal symptoms, but it can lead to discontinuation symptoms and psychological effects such as:
- Irritability or mood swings
- Anxiety or agitation
- Fatigue or low energy
- Headaches
- Difficulty concentrating or “brain fog”
- Sleep disturbances
- Nausea, vomiting, or diarrhea
- Stomach cramps
- Loss of appetite
- Dizziness
- Tremors or numbness in the limbs
- Brain zaps
- Depression relapse
- Suicidal ideation
Some individuals might also experience flu-like symptoms or dizziness. However, many people may not face any issues when discontinuing Bupropion, while others might encounter mild to moderate withdrawal symptoms.
How Long Does It Take to Feel Normal After Quitting Bupropion?
Although most individuals do not face withdrawal symptoms when discontinuing Bupropion, those who do may experience a wide range of symptoms and varying durations before returning to their normal state. Several factors influence the length of Bupropion withdrawal, including the dosage taken, the duration of use, and the individual’s overall health. Each person’s experience is unique, but a typical bupropion withdrawal timeline can be outlined as follows:
- First Few Days (0-3 days) – Bupropion has a half-life of around 21 hours for immediate release, which means individuals will begin to experience discontinuation symptoms within three days from stopping use, which include irritability, mood swings, anxiety, fatigue, headaches, and sleep issues or vivid dreams.
- First 1-2 Weeks – During this time period, withdrawal symptoms typically peak. If Bupropion is being used to treat depression, symptoms of the original condition might start to return if another treatment hasn’t replaced it. Individuals report brain fog, agitation, or depressive symptoms.
- 3-6 Weeks – Most people start to feel more stable by this time. The brain begins to adjust to the absence of bupropion, and symptoms gradually improve.
- 6+ Weeks – Many people return to their “baseline” or normal after about six weeks. However, if bupropion was treating depression, anxiety, or ADHD, symptoms of those conditions can resurface unless managed through other means such as therapy, alternative medications, and lifestyle changes.
While withdrawal from Bupropion is not typically dangerous, it can be uncomfortable and destabilizing for some. In certain instances, mild mood swings or anxiety may persist for a few additional weeks, but if you experience worsening depression, suicidal thoughts, severe anxiety, or intense withdrawal symptoms, it is crucial to consult a healthcare professional.

What Factors Affect the Severity of Withdrawal?
Most individuals who do experience Bupropion withdrawal will typically experience mild to moderate symptoms, and the severity depends on several factors, including:
- Dosage and Duration of Use – Higher doses and longer use of Bupropion increase the likelihood of intensity of withdrawal symptoms. Moreover, those on sustained-release (SR) forms will have more severe symptoms that dissipate more quickly, while those on extended-release (XL) may have delayed onset of withdrawal with longer duration of low-grade symptoms.
- Individual Physiology – Based on how the individual’s body metabolizes the medication can influence how quickly Bupropion leaves the system. Those who metabolize the drug more quickly may experience a faster onset of withdrawal.
- Psychiatric History – Underlying mental health conditions such as depression, anxiety, or bipolar disorder may resurface or worsen during withdrawal, and patients may also experience more significant symptoms.
- Overall Physical Health – People with poor health or comorbid conditions may experience more challenging withdrawal.
- Concurrent Medications or Substance Use – Withdrawal may be complicated by interactions with other medications, use of alcohol, nicotine, or other substances, which may exacerbate or mask withdrawal symptoms.
- Method of Discontinuation – Abrupt cessation increased the risk and severity of withdrawal symptoms. VeryWellMind notes that the safest way to stop taking antidepressants is to slowly taper down dosage with the guidance of healthcare professionals. Tapering allows the body to gradually adjust to the absence of Bupropion, reducing the severity of symptoms.
