Bupropion hydrochloride is a monocyclic antidepressant which is used in a slow-release formulation as a smoking cessation aid. Its side effects include insomnia and dry mouth with seizures occurring in 1 in 1000 patients. In overdose, it can cause tachycardia, conduction defects and convulsions. It is, however, effective in smoking cessation in approximately 20% of patients and may be more effective if combined with nicotine replacement therapy. The key question is whether the risks associated with the drug are justified by the obvious benefits to health from smoking cessation.

Bupropion hydrochloride is currently available in three formulations: immediate-release, sustained-release, and extended-release (ER). Several published reports exist concerning bupropion's history of inducing seizures in both the immediate- and sustained-release formulations. Although the potential of the ER formulation for causing seizures is noted in the drug's prescribing information, there is no previously published report of bupropion ER inducing seizures. In the case reported, a 27-year-old woman who was prescribed bupropion ER as well as clonazepam and lamotrigine (anticonvulsants), hydrocodone bitartrate (for irritable bowel syndrome), and zolipidem tartrate (for depression and associated anxiety and insomnia) experienced a grand mal seizure 6 months after beginning bupropion ER therapy. The patient was taken to the emergency department, where she had a second grand mal seizure 8 hours after the first one. Extended-release bupropion was discontinued, and the patient had not had additional seizures at 8 months follow-up.

Bupropion hydrochloride (HCl) is an antidepressant that has many different biological targets, acting as both a norepinephrine-dopamine reuptake inhibitor as well as a nicotinic antagonist. This second-generation antidepressant is available in 3 bioequivalent formulations: immediate release, sustained release, and extended release, allowing providers to customize a patient's regimen for maximum tolerability and compliance. Although bupropion HCl's safety and tolerability have been demonstrated through several clinical trials, there are still a number of adverse effects that have been reported in the literature. These include headache, agitation, tremor, and insomnia. There is also an increased risk of developing seizures during bupropion treatment. Although urinary symptoms were noted during the clinical trials, these are relatively rare adverse effects. Here we report the case of a 61-year-old man who developed diurnal enuresis during treatment with bupropion HCl sustained release. We will review the adverse effect burden associated with the use of bupropion and discuss the neuropharmacology of urinary symptoms associated with antidepressant treatment.
