Bupropion 150 mg is a widely prescribed medication used primarily to treat depression, manage seasonal affective disorder (SAD), and assist with smoking cessation. Unlike traditional antidepressants, Bupropion affects both dopamine and norepinephrine neurotransmitters, which can improve mood, motivation, and focus. The 150 mg dose is commonly chosen as an initial treatment, with adjustments based on response and tolerability. This comprehensive guide provides information about how Bupropion works, its benefits, dosage guidelines, potential side effects, and precautions.

How Bupropion 150 mg Works

Bupropion is classified as a norepinephrine-dopamine reuptake inhibitor (NDRI). By preventing the reuptake of norepinephrine and dopamine, it increases the levels of these neurotransmitters in the brain. This action can improve mood, increase energy, and reduce cravings in patients using Bupropion for smoking cessation. Unlike selective serotonin reuptake inhibitors (SSRIs), Bupropion has minimal effect on serotonin, which may reduce certain common side effects such as sexual dysfunction.

Bupropion 150 mg is prescribed for several medical conditions:

  • Seasonal Affective Disorder (SAD):Prevents or reduces winter depression episodes.
