It is contraindicated in patients with a seizure disorder. Bupropion Hydrochloride is contraindicated in patients treated with other medications that contain Bupropion because the incidence of seizure is dose dependent. Bupropion may induce seizure and consequently its use is contraindicated in patients with epilepsy. The drug is also contraindicated in patients with a current or prior diagnosis of bulimia or anorexia nervosa because of a higher incidence of seizures noted in such patients treated for bulimia with Bupropion Hydrochloride. The concurrent administration of Bupropion Hydrochloride and a monoamine oxidase (MAO) inhibitor is contraindicated. At least 14 days should elapse between discontinuation of MAO inhibitor and initiation of treatment with Bupropion Hydrochloride. Bupropion Hydrochloride is contraindicated in patients who have shown an allergic response to Bupropion or the other ingredients that make up Bupropion Hydrochloride.
Bupropion HCl is a relatively weak inhibitor of the neuronal uptake of norepinephrine, serotinin and dopamine. The mechanism by which it aids in smoking cessation is presumed to be mediated by its noradrenergic and/or dopaminergic actions.
It should be used with extreme caution, in patients with history of seizure disorders or in patients with other predisposing factors such as severe hepatic cirrhosis or a CNS tumour, and in those undergoing abrupt withdrawal from alcohol or Benzodiazepines. The use of Bupropion in patients with other risk factors for seizures (for example, alcohol abuse, a history of head trauma, diabetes, and drugs known to lower the seizure threshold) should only be undertaken when there are compelling clinical reasons. Bupropion should be used with caution in patients with bipolar depression or psychoses and in patients with a recent history of myocardial infarction or unstable heart disease and in hepatic or renal impairment. Lactation: Enters breast milk; use caution

Pregnancy Data from epidemiological studies of pregnant women exposed to bupropion in first trimester have not identified an increased risk of congenital malformations overall; there are risks to the mother associated with untreated depression in pregnancy A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants during pregnancy at beginning of pregnancy; the women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants; consider risks to the mother of untreated depression and potential effects on tfetus when discontinuing or changing treatment with antidepressant medications during pregnancy and postpartum Lactation Data from published literature report presence of drug and its metabolites in human milk; there are no data on effects of bupropion or metabolites on milk production; limited data from postmarketing reports have not identified a clear association of adverse reactions in the breastfed infant; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from underlying maternal condition
Neuroleptics, lithium and TCAs, benzodiazepine, alcohol, drugs that lower seizure threshold. Increased risk of side effects when co-admin with levodopa. Reduced hepatic clearance with fluoxetine. Caution when administering with agents that will affect hepatic drug metabolizing enzymes. Increased risk of toxicity when used with ritonavir. Potentially Fatal: Concurrent use with MAO inhibitors may cause acute toxicity symptoms and increased risk of fatality.
