Wellbutrin Vs. Zoloft: Drug Comparison

Wellbutrin SR^® (bupropion sustained-release) is an antidepressant that works by inhibiting the reuptake of norepinephrine and dopamine in the brain, which helps improve mood and reduce symptoms of depression. Its FDA-approved indication includes the treatment of major depressive disorder (MDD). Off-label uses may include smoking cessation, anxiety, and attention-deficit hyperactivity disorder (ADHD). Wellbutrin SR is available in sustained-release tablet form, typically taken once or twice daily. Common side effects include insomnia, dry mouth, constipation, and headache, and it has a boxed warning for an increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults during the initial stages of treatment.

Zoloft^® (sertraline) is a selective serotonin reuptake inhibitor (SSRI) used to treat mood disorders by increasing available serotonin levels in the brain, which helps improve mood and reduce symptoms of anxiety and depression. Its FDA-approved indications include the treatment of major depressive disorder (MDD), obsessive-compulsive disorder (OCD), panic disorder (PD), post-traumatic stress disorder (PTSD), social anxiety disorder (SAD), and premenstrual dysphoric disorder (PMDD). Off-label uses may include the treatment of eating disorders and generalized anxiety disorder (GAD). Zoloft is available in tablet and oral solution forms, typically taken once daily. Common side effects include nausea, dizziness, insomnia, and sexual dysfunction, and it carries a boxed warning for an increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults, particularly during the initial treatment period.
