Starting Dose of Adderall XR for New ADHD Female (125 lbs)

For a 125-pound female newly diagnosed with ADHD, the recommended starting dose of Adderall XR is 5-10 mg once daily in the morning. 1

Dosing Considerations

  • The American Academy of Child and Adolescent Psychiatry recommends amphetamine starting doses of 5-10 mg daily 1
  • For adults and adolescents weighing over 40kg (88 lbs), dosing follows adult guidelines with careful titration based on response 1
  • At 125 lbs (approximately 57 kg), this patient falls within the adult dosing category
  • Lower starting doses minimize initial side effects while allowing assessment of therapeutic response

Titration Schedule

  • Begin with 5-10 mg once daily in the morning
  • Evaluate response after 1-2 weeks before considering dose adjustments
  • Increase gradually by 5-10 mg increments based on clinical response and side effects
  • Maximum daily dose should not exceed 50 mg 1
  • Allow sufficient time between dose adjustments (1-2 weeks) to properly assess effects

Administration Considerations

  • Adderall XR should be taken in the morning to minimize insomnia
  • Can be taken with or without food, though be aware that high-fat meals may affect drug absorption 2
  • Capsules can be opened and sprinkled on food if needed 1
  • Consistency in administration timing is important for optimal symptom control

Monitoring Parameters

  • Monitor vital signs (blood pressure, heart rate) before starting and during treatment
  • Track body weight regularly due to potential appetite suppression
  • Assess sleep quality and patterns
  • Evaluate symptom control throughout the day, particularly during demanding tasks
  • Document side effects and their severity

Common Side Effects to Monitor

  • Decreased appetite and weight loss (9.4% in clinical trials) 3
  • Insomnia (12% in clinical trials) 3
  • Headache (16.3% in clinical trials) 3
  • Abdominal pain (10.7% in clinical trials) 3
  • Increased heart rate and blood pressure

Important Considerations

  • Efficacy has been demonstrated in multiple clinical trials with significant improvement in ADHD symptoms 3, 4
  • Extended-release formulation provides symptom control for up to 12 hours 4
  • Adderall has been shown to be effective in reducing ADHD symptoms as rated by both clinicians and patients 5
  • Response is typically seen within the first week of treatment 4

Cautions

  • Avoid in patients with cardiovascular conditions, uncontrolled hypertension, or hyperthyroidism
  • Screen for personal or family history of cardiac issues before initiating therapy
  • Consider potential for misuse or diversion, especially in young adults
  • Schedule the last dose early in the day to minimize insomnia 1
  • Be aware that approximately 25% of patients may not show significant response to medication 6

Starting at a lower dose (5-10 mg) and gradually titrating based on response and tolerability offers the best balance of efficacy and safety for this patient.
