From the Guidelines
The appropriate dosage of amphetamine-dextroamphetamine (Adderall) for ADHD is typically started at 5mg once or twice daily, with possible increases of 2.5 to 5mg weekly, as recommended by the practice parameter for the use of stimulant medications in the treatment of children, adolescents, and adults 1. When considering the treatment of ADHD with amphetamine-dextroamphetamine, it's essential to take into account the individual's age, response to the medication, and potential side effects.
- For children, the starting dose is usually 5mg, given 2-3 times daily, with a maximum total daily dose of 40mg 1.
- Adolescents typically start with the same dose but may require higher total daily doses, up to 60mg 1.
- Adults usually begin with a dose of 5-10mg daily, potentially increasing to 20-60mg daily, divided into 2-3 doses 1. The goal of treatment is to find the lowest effective dose that adequately controls symptoms while minimizing side effects, such as increased heart rate, blood pressure changes, appetite suppression, and sleep disturbances 1. Regular monitoring and follow-up appointments are necessary to assess the patient's response to the medication and adjust the dose as needed, with the aim of achieving the best possible outcome in terms of morbidity, mortality, and quality of life.

From the Research
Amphetamine-Dextroamphetamine Dosage for ADHD
The appropriate dosage of amphetamine-dextroamphetamine (Adderall) for treating Attention Deficit Hyperactivity Disorder (ADHD) can vary depending on several factors, including the patient's age, weight, and response to the medication.
- The typical starting dose for adults with ADHD is 5-10 mg per day, which can be gradually increased to achieve optimal results 3.
- However, the optimal dosage for children and adolescents may differ, and it is essential to consult a healthcare professional for personalized guidance.
