PRODUCT CONSIDERATIONS When is coverage needed? Time to onset Duration of effect Dosage Forms ER/XR dosage forms should not be chewed, crushed, divided Cost Convenience Abuse potential? Can be given just on school days
CARDIOVASCULAR RISK Sudden cardiac death is rare Uncertain association Baseline ECG: AAP doesn t recommend AHA says it is reasonable Evaluate cardiac history at baseline Congenital heart disease or cardiac abnormality: collaboration between family, ADHD specialist, pediatric cardiologist BP and HR s are usually mild Cortese et al. J Child Psychol Psychiatry 2013;54(3)227-46.
ADDITIONAL ADVERSE EFFECTS (STIMULANTS) appetite growth velocity Abdominal pain Headaches Insomnia Irritability Emotional lability Abuse potential Xerostomia Worsen tics Visual disturbance FDA Warning: sustained or prolonged erections Subcommittee on ADHD.

Somnolence Appetite & growth suppression Pediatric and Neonatal Lexi-Drugs Online
BUPROPION Not FDA approved or in AAP guidelines Weak inhibitor of norepinephrine & dopamine IR & SR/XL tablets (start with IR & titrate) Don t crush or chew SR/XL dosage forms Adverse effects Risk of suicidal ideation during initiation Anxiety/insomnia/activation BP Lower seizure threshold Pediatric and Neonatal Lexi-Drugs Online

Psychiatry Medications Depression & Anxiety Medications for Autism Spectrum Disorder
DEPRESSION Prevalence: 0.5 3.5% More common in females More common in 12-17 years Risk factors Family history Early exposure to adversity Psychosocial stressors Traumatic brain injury Gender dysphoria/homosexuality Chronic illness Kreys TM. Pediatric Depression. Pediatric Pharmacotherapy. ACCP
DEPRESSION TREATMENT Consider patient-specific factors Psychotherapy/CBT Pharmacotherapy Selective serotonin-reuptake inhibitors (SSRIs) Serotonin-norepinephrine-reuptake inhibitors (SNRIs) Bupropion (dopamine/norepi reuptake inhibitor) Mirtazipine Venlafaxine TCAs/MAOIs not typically recommended Acute, continuation, & maintenance phases Hughes CW et al. J Am Acad Child Adolesc Psychiatry. 2007;46:667-86. Birmaher B et al. J Am Acad Child Adolesc Psychiatry. 2007;46:1503-26
