Wellbutrin is the brand name for the prescription drug bupropion. It is classified as an atypical antidepressant used to treat major depressive disorder and to support smoking cessation. The drug works by inhibiting the reuptake of the neurotransmitters norepinephrine and dopamine in the brain. By increasing the availability of these chemicals it helps improve mood and reduce the urge to smoke. Unlike many other antidepressants it does not significantly affect serotonin levels. This selective action contributes to its distinct side effect profile and lower risk of weight gain. The sustained elevation of norepinephrine and dopamine is thought to enhance motivation and emotional regulation. Clinical studies have shown that these mechanisms lead to symptom relief in many patients when used as directed.

Wellbutrin is an atypical antidepressant used to treat major depression and to help people quit smoking. It blocks the reuptake of the neurotransmitters norepinephrine and dopamine. This increases the amount of these chemicals available in the brain. Higher levels of norepinephrine and dopamine improve mood and motivation. The drug acts as a selective norepinephrine-dopamine reuptake inhibitor which differentiates it from other antidepressants. By elevating these pathways it restores balance in mood regulation and assists in smoking cessation.

Common side effects of Wellbutrin include headache, dry mouth, insomnia, and nausea. Some users may experience dizziness, weight loss, or a decreased appetite. Anxiety or agitation can also occur in certain individuals. Rarely, it may cause ringing in the ears or a metallic taste. Most of these effects are mild and often improve over time. They typically do not require medical intervention unless they persist. Monitoring symptoms can help determine if adjustments are needed. The drug is generally well tolerated by most patients.
