Combination Therapy for Depression and ADHD

Introduction to Combination Therapy

The American Academy of Child and Adolescent Psychiatry guidelines establish that combination therapies are appropriate when used to treat multiple disorders in the same patient, such as a stimulant and an SSRI for ADHD and anxiety/depression 1, 2

The combination of lisdexanfetamine for ADHD, escitalopram for depression, and aripiprazol in low dose as an augmenter or for residual symptoms follows the principle that combinations are used to treat multiple disorders in the same patient 1, 2

There are no clinically significant pharmacological interactions between stimulants and SSRIs, as SSRIs are metabolized in the liver while 80% of stimulant metabolism is extra-hepatic 3
The American Academy of Child and Adolescent Psychiatry recommends this combination for patients with ADHD and comorbid depression, although there are no specific controlled trials 3

The combination of two non-MAOI serotonergic agents (escitalopram + lisdexanfetamine) requires monitoring but is not contraindicated 6
It is recommended to start with low doses and titrate slowly, and to monitor symptoms in the first 24-48 hours after dose changes 6

The American Academy of Child and Adolescent Psychiatry suggests that administration of lisdexanfetamine, escitalopram, and aripiprazol at breakfast is appropriate and practical 6, 7
A clear treatment and monitoring plan should be developed before initiating this combination, including education of the patient and family, and obtaining informed consent 1, 2, 8
Cardiovascular history should be assessed due to the stimulant, and absolute contraindications such as active psychosis, schizophrenia, or manic episodes with psychosis should be excluded 7, 9

Monthly consultations are recommended initially for dose adjustment and response evaluation, with monitoring of blood pressure, heart rate, weight, and growth (if applicable) 9
Symptoms of serotonin syndrome should be evaluated, especially in the first weeks, and standardized assessment scales should be used for ADHD and depression symptoms 6, 9

The American Academy of Child and Adolescent Psychiatry guidelines advise against attributing all symptoms to biological causes, and recommend avoiding combination of medications from the same class without specific evidence 1, 2, 8
Abrupt discontinuation, particularly of escitalopram, should be avoided, and the need for psychosocial interventions should not be ignored 1, 6
