What is an antidepressant that may cause mania and insomnia?

Bupropion, commonly known by its brand name Wellbutrin, is an antidepressant that can potentially cause mania and insomnia in some individuals. It is a norepinephrine-dopamine reuptake inhibitor (NDRI) and is often used to treat depression and aid in smoking cessation. Due to its stimulating effects, it may trigger manic episodes, especially in those with Bipolar disorder. As with any medication, it is important for patients to discuss potential side effects with their healthcare provider.
