Bupropion is an antidepressant medication that also aids in smoking cessation. It belongs to the therapeutic class of antidepressants, addiction & quit smoking agents and is available in a pill form with a strength of 150 mg. In Hong Kong, bupropion is a prescription-only (Rx) medicine regulated by the Department of Health. It is marketed under various generic names and is often prescribed for major depressive disorder and as an aid to help people stop smoking.
Bupropion acts as a norepinephrine-dopamine reuptake inhibitor (NDRI). By blocking the reabsorption of norepinephrine and dopamine into nerve cells, it increases the levels of these neurotransmitters in the brain. Elevated dopamine and norepinephrine improve mood, increase energy, and reduce cravings for nicotine.
These indications are recognized by regulatory agencies in Hong Kong and internationally.
Bupropion has been studied for several off-label applications. When such use is considered, it must be overseen by a qualified healthcare professional.
Off-label use requires medical supervision and individualized risk assessment.

Bupropion can be combined with certain other antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), but only under close medical supervision to monitor for interactions and side-effect profiles. Your prescriber will assess the benefit-risk balance before adding another agent.
Take the medication early in the morning and avoid consuming caffeine late in the day. If insomnia persists, discuss dosage timing or possible dose reduction with your healthcare provider; they may adjust the regimen to improve sleep quality.
Bupropion does not typically raise blood pressure, but nicotine-withdrawal symptoms and certain drug interactions can affect cardiovascular status. Regular blood pressure monitoring is advisable, especially during the initial weeks of therapy.
Most individuals notice a reduction in nicotine cravings within the first week, with the greatest benefit occurring after 4-6 weeks of consistent use. It should be combined with a comprehensive quit-smoking plan that includes counseling and behavioral support.

It should only be prescribed during pregnancy if the potential benefits outweigh any potential risks, after thorough discussion with a qualified obstetrician.
Symptoms may include sudden loss of consciousness, convulsive movements, or a staring episode followed by muscle rigidity. If any of these occur, seek emergency medical care immediately, as seizures are a serious adverse effect.

Bupropion works by modulating dopamine and norepinephrine pathways, whereas varenicline acts as a nicotine receptor partial agonist. The side-effect profiles differ: bupropion may cause insomnia and dry mouth, while varenicline is more commonly associated with vivid dreams and nausea. Choice of therapy depends on individual health status and treatment preferences.
