Bupropion – Uses, Mechanism, and Safety Guide

When working with bupropion, a prescription medication that acts on brain chemistry to lift mood and curb cravings. Also known as Wellbutrin, it belongs to the class of antidepressants, drugs used to treat depressive disorders by balancing neurotransmitters and doubles as a smoking cessation aid, helping people quit nicotine by reducing withdrawal symptoms. Chemically, bupropion is a norepinephrine‑dopamine reuptake inhibitor, which blocks the reabsorption of norepinephrine and dopamine, increasing their levels in the brain. This triple identity explains why doctors prescribe it for major depressive disorder, seasonal affective disorder, and as part of a quit‑smoking plan.

Typical adult dosing starts at 150 mg once daily and may increase to 300 mg split into two doses, but the exact schedule depends on the condition being treated. Because bupropion is metabolized mainly by the liver enzyme CYP2B6, drugs that inhibit or induce this pathway can change its blood levels. For example, certain antidepressants, antiretrovirals, or even large amounts of caffeine can boost side‑effects like insomnia, jitteriness, or a rise in blood pressure. The most common adverse reactions are dry mouth, headache, and mild nausea; however, a rare but serious risk is a seizure, especially at higher doses or in patients with a history of eating disorders. Staying hydrated, avoiding excessive stimulant intake, and following the prescribed timing can keep these risks low. Many of our articles—such as the piece on caffeine interactions and the guide to safe acetaminophen use—show how careful timing and awareness of metabolism can make a big difference when taking bupropion alongside other medicines.
