From the Research

Abilify (aripiprazole) is a beneficial treatment option for depression, alcohol use disorder, and complex trauma, with the most robust evidence supporting its use in depression as an adjunctive treatment at doses of 2-15mg daily. For depression, Abilify is FDA-approved as an adjunctive treatment when antidepressants alone are insufficient, typically starting at 2-5mg and adjusting based on response, as demonstrated in studies such as 1 which showed significant improvements in depressive symptoms. For alcohol use disorder, Abilify is used off-label at similar doses (5-15mg daily), with some evidence suggesting it may reduce cravings and drinking days by modulating dopamine pathways involved in reward and addiction, as seen in 2. For complex trauma, Abilify is also used off-label at lower doses (2-10mg daily) to address mood instability, irritability, and intrusive thoughts when other treatments have failed. Common side effects include akathisia (restlessness), weight gain, and metabolic changes, highlighting the importance of regular monitoring of weight, blood glucose, lipids, and movement disorders, as noted in 3 and 4. Treatment duration varies: for depression, reassess after 4-6 weeks; for alcohol use disorder, 3-6 months initially with possible longer-term use; and for trauma symptoms, regular evaluation every 2-3 months. Abilify works as a partial dopamine agonist, helping stabilize dopamine and serotonin systems that are often dysregulated in these conditions, as explained in 5. Key considerations in the use of Abilify include:

  • Starting with a low dose and gradually increasing as needed and tolerated
  • Monitoring for side effects and adjusting the treatment plan accordingly
  • Combining Abilify with other therapies, such as antidepressants or psychotherapy, for optimal outcomes
  • Regularly assessing the effectiveness of treatment and making adjustments as necessary to ensure the best possible outcomes in terms of morbidity, mortality, and quality of life.
