Wellbutrin is a prescription medication primarily used to treat depression and anxiety disorders. It is also prescribed to help people quit smoking. The active ingredient in Wellbutrin is bupropion, which works by affecting the balance of certain chemicals in the brain, particularly dopamine and norepinephrine. This can help improve mood and reduce feelings of sadness or anxiety. Wellbutrin is available in various forms, including immediate-release and extended-release tablets. Common side effects may include dry mouth, insomnia, and increased sweating. It is important for patients to discuss their medical history with their healthcare provider before starting Wellbutrin, as it may not be suitable for everyone.
