Is Bupropion similar to Zoloft? (3+ key differences)

In this article, we will discuss whether  Sertraline (Zoloft) and Bupropion (Wellbutrin) are similar medications. We will also discuss the key differences to help you understand the therapeutic uses and potential side effects of these medications.

Is Bupropion similar to Zoloft?

Bupropion (Wellbutrin) is not similar to Sertraline (Zoloft), but both of these medications are antidepressants. Although both drugs can be used to treat mental health conditions, they have different mechanisms of action and are usually prescribed for different purposes.

The choice between Bupropion and Zoloft would depend on the specific diagnosis, individual patient factors and the potential side effects of the two medications.

Always consult your healthcare provider for guidance on medication selection and potential risks and benefits.

What are the differences between Zoloft and Bupropion?

Bupropion and Zoloft are antidepressant medications. Although both medications are used to treat some of the same mental health conditions, they work through different mechanisms.

Mechanism of action

Zoloft belongs to a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the level of serotonin in the brain. Serotonin is a mood stabilizer chemical, which can help improve mood and reduce symptoms of anxiety and depression (1).

 Bupropion belongs to a class of medications called norepinephrine dopamine reuptake inhibitors (NDRIs). It works by increasing the level of neurotransmitters norepinephrine and dopamine in the brain which helps in mood regulation and the reduction in depression symptoms (2).

SSRIs and NDRIs function similarly by elevating the level of certain brain chemicals called neurotransmitters in the brain. However, SSRIs like Zoloft increase serotonin levels while Bupropion elevates nor-epinephrine and dopamine levels in the brain.

Therapeutic uses 

Therapeutic uses of Zoloft include (1):

  • Major depressive disorder
  • Obsessive-compulsive disorder (OCD)
  • Social anxiety disorder
  • Premenstrual dysphoric disorder
  • Post-traumatic stress disorder
  • Panic disorder

  • Major depressive disorder
  • Seasonal affective disorder

These side effects can vary among individuals depending on factors like the individual’s age, current symptoms, underlying health condition, weight and dosage strength of the medication used.

Both Zoloft and Bupropion can cause withdrawal symptoms if discontinued abruptly. Always make sure not to make any changes to your dosage without consulting your doctor first.

What does research suggest?

Studies comparing the effectiveness of Zoloft and Bupropion as antidepressants have suggested that there are no significant differences in terms of efficacy or tolerability (5).

Research studies also suggest that both drugs have comparable effects in alleviating symptoms of anxiety disorders. Furthermore, they have a similar onset of therapeutic benefits with improvement of symptoms often seen as early as two weeks after starting treatment.

Can you take Bupropion and Zoloft together?

It is possible to take Bupropion and Zoloft together for depression under the proper guidance of your healthcare provider as they can offer added benefits due to their different brain neurotransmitter influences. However, it may raise the risk of side effects and potentially lead to overdose.

Consulting your healthcare provider before using these medications together is important for managing potential risks and ensuring well-being.

Final thoughts

Bupropion and Zoloft are both antidepressants used to treat mental health conditions but they differ in their mechanism of action, primary uses and potential side effects. While they can both be effective for certain disorders, the choice between them depends on the individual’s diagnosis, symptoms and medical history. Always consult your healthcare provider for personalized treatment.
