Bupropion is an aminoketone antidepressant classified as a norepinephrine-dopamine reuptake inhibitor (NDRI). It is one of the most widely prescribed antidepressants in the United States, ranking among the top 20 most prescribed medications. Bupropion is FDA-approved to treat Major Depressive Disorder (MDD), Seasonal Affective Disorder (SAD) (as Wellbutrin XL), and smoking cessation (as Zyban). It is also used off-label for ADHD, antidepressant-induced sexual dysfunction, neuropathic pain, and weight management. Unlike SSRIs, Bupropion does not typically cause sexual side effects or weight gain, making it a popular choice for patients who have experienced those issues with other antidepressants.

Bupropion works by blocking the reuptake of two key neurotransmitters in the brain: norepinephrine and dopamine. By preventing these chemicals from being reabsorbed back into nerve cells, Bupropion increases their availability in the brain, which helps improve mood, energy, and concentration. Unlike most other antidepressants (SSRIs and SNRIs), Bupropion has minimal effect on serotonin reuptake. This unique mechanism is why it tends to have a different side effect profile — with less risk of sexual dysfunction and weight gain — compared to serotonin-based antidepressants.

Bupropion scores a 78 out of 100 on our findability scale, meaning it is generally available but you may encounter minor gaps at certain pharmacies. Bupropion XL 300 mg has been the most affected strength, with intermittent supply disruptions reported since 2023 due to increased demand and manufacturing capacity constraints. As of early 2026, supply has been improving, but sporadic shortages of certain generic XL strengths may still occur. If your usual pharmacy is out of stock, try checking independent pharmacies or using Medfinder to locate it nearby.
Bupropion can be prescribed by a wide range of healthcare providers, including:
Bupropion is also widely available through telehealth platforms, making it accessible without an in-person visit.
No, Bupropion is not a controlled substance. It is not scheduled by the DEA, which means it can be prescribed with standard prescriptions (including refills) and does not require the special prescribing restrictions that apply to controlled substances like stimulants or benzodiazepines. However, Bupropion does carry a boxed warning about increased risk of suicidal thoughts and behavior in young adults under 25, and it has a dose-dependent risk of seizures, so it should be used under medical supervision.
Most side effects of Bupropion are mild and often improve after the first few weeks of treatment. Common side effects include:
Serious side effects are rare but can include seizures (especially at doses above 450 mg/day), severe allergic reactions, significant blood pressure elevation, and worsening of suicidal thoughts in young adults. Contact your doctor immediately if you experience any serious side effects.
