Yes, auditory hallucinations are a rare but documented psychiatric side effect of bupropion (Wellbutrin). They are more likely to occur at higher doses, during rapid dose increases, or in individuals who are sleep-deprived. [1, 2, 3, 4]

Because bupropion enhances dopamine and norepinephrine, it can sometimes trigger psychosis or perceptual disturbances in susceptible patients, such as those with bipolar disorder or a history of psychosis. Auditory hallucinations may also be confused with, or accompanied by, drug-induced tinnitus (ringing in the ears). [1, 2, 3, 4, 5]

The FDA explicitly lists neuropsychiatric reactions, including hallucinations, as a reason to contact your doctor immediately and potentially discontinue the medication. [1, 2]
