What Is Wellbutrin? Is Wellbutrin An Ssri?
Wellbutrin is a medication used to treat depression. Its generic name is bupropion. Is bupropion an SSRI, then? Wellbutrin is not an SSRI (selective serotonin reuptake inhibitor). Instead, it belongs to a different class of antidepressants called NDRIs (norepinephrine-dopamine reuptake inhibitors).
Wellbutrin works by changing the levels of certain chemicals in the brain, specifically norepinephrine and dopamine. These chemicals help control mood and emotions. By blocking the reuptake (or reabsorption) of these chemicals, Wellbutrin increases their levels in the brain, which can help improve mood and reduce symptoms of depression.
Wellbutrin comes in several forms and dosages:
- IR (immediate-release): Taken multiple times a day.
- SR (sustained-release): Taken twice a day.
- XL (extended-release): Taken once a day.
The most common starting dose for Wellbutrin XL is 150mg once daily, which may be increased to 300 mg once daily.
Wellbutrin is approved to treat major depressive disorder and prevent seasonal affective disorder (seasonal depression). Itโs also sometimes used off-label to help people quit smoking, treat ADHD, and manage depression in people with bipolar disorder.
What Is Lexapro? Is Lexapro An Ssri?
Lexapro is another medication used to treat depression and anxiety. Its generic name is escitalopram. Unlike Wellbutrin, Lexapro is an SSRI (selective serotonin reuptake inhibitor).
Lexapro works by increasing the levels of serotonin in the brain. Serotonin is a chemical that helps regulate mood, sleep, and emotions. By blocking the reuptake of serotonin, Lexapro makes more of this chemical available in the brain, which can help improve mood and reduce symptoms of depression and anxiety.
Lexapro comes in different forms and dosages:
- Tablets: Available in 5 mg, 10mg, and 20mg doses.
- Oral solution: Available in 1mg per milliliter (mg/mL).
The typical starting dose for Lexapro is 10mg once daily, which can be increased to a maximum of 20mg per day if needed.
Lexapro is approved to treat major depressive disorder in adults and adolescents aged 12+. It is also approved to treat GAD (generalized anxiety disorder) in adults and children aged 7 and older. Additionally, Lexapro is sometimes used off-label to treat other conditions like OCD, panic disorder, and PTSD.
