Precautions and warnings

Bupropion should be used very carefully in people with a history of seizures or with conditions that increase the risk of seizures, such as severe liver disease, brain tumors, or those who are suddenly stopping alcohol or benzodiazepines. People with other risk factors for seizures—like alcohol abuse, past head injuries, diabetes, or who are taking drugs that can cause seizures—should only take bupropion if it is truly necessary. It should also be used with caution in people with bipolar disorder, psychosis, recent heart attacks, unstable heart disease, liver or kidney problems.

  • and insomnia often occur during the initial stages of Bupropion therapy. Other relatively common side effects reported with Bupropion include fever

  • dizziness
  • nausea
  • vomiting
  • constipation
  • tremor
  • sweating
  • and skin rashes. Hypersensitivity reactions
  • ranging from pruritus

  • angio-oedema

  • and anaphylactoid reactions have been reported.

Drug Interactions

Neuroleptics, lithium, tricyclic antidepressants (TCAs), benzodiazepines, alcohol, and other drugs that lower the seizure threshold can increase side effects when taken with levodopa. Fluoxetine can reduce how quickly the liver clears these drugs. Be cautious when giving this medication with other drugs that affect liver enzymes. Using it with ritonavir can raise the risk of toxic effects.

**Warning:** Taking this drug together with MAO inhibitors can cause severe toxicity and may be life-threatening.

Contraindications

Bupropion Hydrochloride should not be used in people who have seizure disorders, because it can increase the chance of having a seizure, and this risk goes up with higher doses. It should also not be used with other medications that contain bupropion. People who have or have had bulimia or anorexia nervosa should not take bupropion, since studies show they are more likely to have seizures when using it. Bupropion should never be taken at the same time as a monoamine oxidase inhibitor (MAOI); you need to wait at least 14 days after stopping an MAOI before starting bupropion. Lastly, anyone who has had an allergic reaction to bupropion or any of its ingredients should not take this medication.

Mode of actions

Bupropion HCl slightly blocks the reuptake of norepinephrine, serotonin, and dopamine in the brain. It is thought to help people quit smoking mainly because of its effects on norepinephrine and dopamine.
