From the Guidelines
For a patient with treatment-resistant depression who hasn't responded to Venlafaxine 225 mg/day and Aripiprazole 10 mg/day, the next step would be to consider augmentation with lithium (300-900 mg/day) or switching to a different antidepressant class such as an MAOI like tranylcypromine (starting at 10 mg twice daily). Given that the patient has already been on Venlafaxine for four weeks and Abilify for an unspecified duration with no response, it's crucial to reassess the treatment plan. According to the American College of Physicians guideline 1, if a patient does not have an adequate response to pharmacotherapy within 6 to 8 weeks, treatment should be modified. The patient's current regimen has not provided the desired outcome, suggesting a need for a change. Some key considerations include:
- Augmentation strategies: Adding another medication to enhance the effects of the current antidepressant. Lithium is a common augmentation agent for treatment-resistant depression.
- Switching antidepressants: If the current medication is not effective, switching to a different class of antidepressants, such as MAOIs, might be beneficial.
- Non-pharmacological approaches: For severe cases, options like transcranial magnetic stimulation (TMS) or electroconvulsive therapy (ECT) could be considered.
- Psychotherapy: Combining medication changes with evidence-based psychotherapy, such as cognitive behavioral therapy, can be beneficial. It's essential to discuss the risks and benefits of each option with the patient, considering their symptom profile, previous responses to medications, side effects, and personal preferences 1.

Next Steps for Treatment-Resistant Depression
Given the lack of response to Venlafaxine 225 mg/day and Abilify 10 mg/day, the next steps for a patient with treatment-resistant depression may include:
- Considering alternative antidepressant medications, such as mirtazapine, which has been shown to be effective in treatment-resistant depression 2
- Augmenting the current treatment regimen with other medications, such as atypical antipsychotics or mood stabilizers, although the efficacy of these combinations has not been extensively studied 3
- Evaluating the patient's treatment history and adjusting the treatment plan accordingly, taking into account factors such as safety, tolerability, efficacy, and simplicity 4
- Exploring non-pharmacological treatments, such as therapy or lifestyle changes, which may be used in conjunction with medication to improve treatment outcomes 5
Alternative Treatment Options
Some alternative treatment options that may be considered for treatment-resistant depression include:
- Mirtazapine, which has been shown to be effective in comparison to other antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) 2
- Combination therapy with mirtazapine and aripiprazole, which has been shown to be safe and well-tolerated, and may be useful in treatment-resistant depression 6
- Other antidepressant medications, such as tricyclic antidepressants or monoamine oxidase inhibitors, although these may have different side effect profiles and efficacy compared to newer medications 5
