Bupropion is a neuropsychiatric medication used to treat depression and assist in smoking cessation. It primarily works by regulating dopamine and norepinephrine levels in the brain to improve mood and reduce cravings for cigarettes. Unlike traditional antidepressants, it does not act on the serotonin system, thus having a unique mechanism of action.
Bupropion is widely used for treating adult depression and has been approved as a smoking cessation aid. Its antidepressant effects typically become evident after 2-4 weeks of treatment, while its efficacy in smoking cessation is usually enhanced when combined with behavioral therapy. This medication must be used under medical supervision; do not adjust the dosage or discontinue without professional guidance.
The generic name of this medication is Bupropion. Common brand names include:
Different brands may have variations in dosage or release formulations, so it is important to select the appropriate formulation as directed by your healthcare provider.
Bupropion is classified as a Norepinephrine-Dopamine Reuptake Inhibitor (NDRI). This class of drugs selectively inhibits the reuptake of neurotransmitters, differing from selective serotonin reuptake inhibitors (SSRIs) and other antidepressants in their mechanism of action.
It is not classified as an amphetamine-type stimulant, but due to its influence on dopamine, it may cause mild nervous excitement. This classification makes it advantageous in treating certain types of depression or nicotine withdrawal syndromes.

Does Bupropion need to be taken with specific meal times? How should I handle missed doses?
Bupropion can be taken on an empty stomach or with food, but it is recommended to take it at the same time each day to maintain stable drug levels. If a dose is missed and more than 4 hours have passed since the scheduled time, take it as soon as possible; if it is close to the next dose, skip the missed dose and do not double up. If gastrointestinal discomfort occurs, taking the medication with food may help alleviate symptoms.
What should I do if I experience insomnia or increased anxiety while using Bupropion?
Some patients may experience insomnia or heightened anxiety early in treatment. It is advised to take the medication before 4 PM to reduce sleep disturbances. If symptoms persist for more than a week, consult your doctor about adjusting the dose or using non-pharmacological measures such as relaxation techniques or short-term sleep aids.
Does Bupropion interact with other antidepressants or prescription drugs?
Bupropion should not be used with monoamine oxidase inhibitors (MAOIs); a 14-day washout period is required before switching. When combined with warfarin or antiplatelet drugs, there may be an increased risk of bleeding, requiring regular blood clotting monitoring. Always inform your healthcare provider of all medications, supplements, and OTC drugs you are taking.
Are there specific dietary or exercise precautions during treatment?
It is recommended to avoid excessive caffeine intake, as Bupropion may enhance caffeine-induced anxiety or palpitations. Regular aerobic exercise such as brisk walking or swimming can synergistically improve mood, but vigorous activity immediately after taking medication should be avoided to prevent blood pressure fluctuations. Smokers should avoid alcohol during the initial cessation period to minimize discomfort.
How should I safely discontinue medication after completing treatment? What are the risks of abrupt discontinuation?
Bupropion should be tapered gradually under medical supervision, typically reducing the dose by 25-50% weekly over 2-4 weeks. Abrupt discontinuation may cause dizziness, headaches, rebound anxiety, or electric shock sensations. If mood swings or other withdrawal symptoms occur, seek medical advice promptly to reassess the treatment plan.
