Bupropion, a versatile medication, plays a significant role in modern medicine. It is primarily prescribed to treat major depressive disorder, seasonal affective disorder (SAD), and to support smoking cessation.
Approved by the FDA in 1985 and initially marketed as Wellbutrin, Bupropion is also available under brand names like Wellbutrin SR, Wellbutrin XL, Zyban, and Aplenzin. Its popularity has grown steadily, with annual prescriptions rising from 17 million in 2004 to 28.89 million today.
Bupropion is commonly prescribed to treat depression and seasonal affective disorder (SAD), which typically occurs during winter when daylight is limited. Research shows its effectiveness, particularly for individuals with atypical depression or those who haven’t responded well to other treatments.
Additionally, Bupropion aids in reducing nicotine cravings and withdrawal symptoms, previously marketed as Zyban until its discontinuation in the US in 2022. It is also sometimes used off-label for ADHD management and weight control, though these are not FDA-approved uses.
Bupropion works by inhibiting the reuptake of norepinephrine and dopamine, enhancing their levels in the brain. Unlike SSRIs, it has minimal effect on serotonin, reducing the risk of side effects like sexual dysfunction or weight gain, making it a distinct and effective antidepressant option.
Bupropion is typically well-tolerated, but it may cause side effects that can vary in frequency and severity. Not everyone will experience them, and individual reactions can differ.
This is the most common side effect, affecting up to 80% of users.
Nausea and vomiting occur in up to 30% of people.
Sleep disturbances, including difficulty falling asleep, may happen.
Some side effects are relatively common but often improve as the body adjusts.

Mild tremors in the hands or limbs can occur.
A decreased appetite or weight loss may affect some individuals.
There is a rare but serious risk, particularly at higher doses.
Although uncommon, allergic reactions like skin rash, hives, swelling, or difficulty breathing are possible.
Bupropion is not classified as addictive and has a lower potential for abuse compared to medications like benzodiazepines or opioids. However, it’s essential to follow the prescribed guidelines to minimize the risk of withdrawal symptoms or overdose.
Suddenly stopping Wellbutrin or quickly reducing the dose of Bupropion may cause withdrawal symptoms in some individuals, though they are generally less common than with other antidepressants. The severity and duration of these symptoms can vary from person to person.
Common Bupropion withdrawal symptoms may include:
These include:
These include:
A drug’s half-life is the time it takes for half of the medication to leave the body. Bupropion’s half-life is more complex, influenced by factors such as its formulation, dosage, and individual characteristics like age and medical history.
Shortest half-life of around 3-4 hours.
This has a half-life of around 9-12 hours.
Longest half-life of around 21 hours.
The correct dosage of Bupropion depends on the condition being treated. Chronic dosing is typically used for managing depression, while acute dosing is common for smoking cessation and seasonal affective disorder.
With regular daily use, Bupropion’s active metabolites build up in the body, extending its effective half-life to approximately 21 hours.
Bupropion may interact with several medications, including monoamine oxidase inhibitors (MAOIs) and selective serotonin reuptake inhibitors (SSRIs). Other possible interactions include:
It’s important for patients to inform their healthcare providers about all medications, including over-the-counter drugs and supplements. Additionally, avoid taking multiple medications that both contain Bupropion.
It’s essential for patients to maintain open communication with their healthcare providers, particularly regarding any existing medical conditions. Bupropion is not recommended for individuals with:
Additionally, drinking alcohol while taking Bupropion can heighten the risk of experiencing unpleasant side effects.
Bupropion’s distinct mechanism of action and better tolerability compared to other antidepressants have made it increasingly popular. However, it’s important to remember that it is a prescription medication with potential risks, requiring careful monitoring by a healthcare professional.
