From the Guidelines

Switching from Wellbutrin to Sertraline should be done under medical supervision, using a cross-taper approach to minimize withdrawal symptoms and side effects, as evidenced by low-quality evidence from trials comparing switching strategies 1. When switching from Wellbutrin (bupropion) to Sertraline (Zoloft), it is essential to consider the different mechanisms of action of these antidepressants.

  • Wellbutrin primarily affects dopamine and norepinephrine,
  • while Sertraline affects serotonin. This difference necessitates a careful transition to maintain mood stability and minimize potential side effects. According to low-quality evidence from one trial, there was no difference in remission or depression severity when switching from one selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) to another, including sertraline or venlafaxine 1. However, the specific switch from Wellbutrin to Sertraline requires a tailored approach. A common strategy involves a cross-taper, where the Wellbutrin dose is gradually reduced (e.g., by 50-100mg every 5-7 days) while simultaneously starting and increasing Sertraline (beginning at 25-50mg and increasing by 25-50mg weekly) until reaching the target dose, usually between 50-200mg daily. This gradual transition can help mitigate withdrawal symptoms from Wellbutrin and side effects from Sertraline, such as headaches, nausea, sleep changes, or increased anxiety. The entire switch process typically takes 2-4 weeks, depending on the current Wellbutrin dose and the target Sertraline dose. Given the low-quality evidence available, the decision to switch and the method of switching should prioritize minimizing risks and maximizing the patient's quality of life, under the guidance of a healthcare provider 1.

From the Research

Switching from Welbutrin to Sertraline

To switch from Welbutrin (bupropion) to Sertraline, it is essential to consider the potential risks and benefits of this transition.

  • The combination of bupropion and selective serotonin reuptake inhibitors (SSRIs) like sertraline can increase the risk of serotonin syndrome, a potentially fatal complication 2.
  • There is limited guidance on tapering and discontinuing antidepressants, including switching from one medication to another 3.
  • Bupropion and sertraline have been compared in several studies, with similar efficacy for the treatment of depression, but differing side effect profiles 4, 5.
  • Bupropion is often added to treatment with SSRIs to enhance antidepressant response or ameliorate antidepressant-associated sexual dysfunction 6.

Key Considerations

  • When switching from bupropion to sertraline, it is crucial to monitor for signs of serotonin syndrome, such as myoclonic jerks, clumsiness, and gait difficulties 2.
  • The transition should be done under the guidance of a healthcare professional, with careful monitoring of the patient's symptoms and side effects.
  • Patients should be informed about the potential risks and benefits of the switch and should be closely followed up to minimize any adverse effects.

Potential Side Effects

  • Sertraline is associated with a higher risk of nausea, diarrhea, somnolence, and sexual dysfunction compared to bupropion 4, 5.
  • Bupropion, on the other hand, may have a lower risk of these side effects, but can increase the risk of serotonin syndrome when combined with SSRIs 2.
