From the Guidelines

The recommended duration for adults with ADHD to take Adderall is indefinite, as ADHD is a chronic condition, and treatment should be continued as long as it is effective and tolerated, with regular reassessments every 6-12 months. Many adults with ADHD may need to continue medication long-term, often for years, to manage their symptoms effectively. Adderall is usually started at a low dose (5-10mg once or twice daily) and gradually adjusted based on symptom control and side effects, with most adults requiring 20-40mg daily divided into multiple doses 1.

Key Considerations

  • Treatment should be regularly reassessed every 6-12 months to evaluate continued need, effectiveness, and any side effects 1.
  • Some patients may benefit from periodic "medication holidays" to assess ongoing need and minimize tolerance, particularly during times of lower cognitive demands.
  • Adderall works by increasing dopamine and norepinephrine levels in the brain, which helps improve attention, focus, and impulse control in people with ADHD 1.
  • The decision to continue or discontinue medication should be made collaboratively between the patient and healthcare provider based on symptom control, functional improvement, and quality of life considerations.

Monitoring and Side Effects

  • Clinical guidelines generally recommend monitoring of pulse and blood pressure when prescribing psychostimulant medication, such as Adderall, due to potential increases in blood pressure and heart rate 1.
  • Common adverse effects of Adderall include decreased appetite, sleep disturbances, increased blood pressure and pulse, headaches, irritability, and stomach pain 1.
  • Long-term treatment with psychostimulants, including Adderall, may be associated with a statistically significant reduction in height and weight gain, which requires careful monitoring 1.

From the Research

Duration of Adderall Treatment for Adults with ADHD

The recommended duration for adults with Attention Deficit Hyperactivity Disorder (ADHD) to take Adderall (amphetamine/dextroamphetamine) to reduce symptoms is not strictly defined, as it depends on various factors including individual response to treatment, presence of comorbid conditions, and side effects experienced. However, several studies provide insights into the efficacy and safety of long-term Adderall use in adults with ADHD.

Efficacy and Safety of Long-term Adderall Use

  • A study published in 2000 found that Adderall was effective in reducing ADHD symptoms in adults, with positive responses occurring at relatively low doses 2.
  • Another study from 2016 noted that amphetamines, including Adderall, have robust evidence of efficacy in treating adult ADHD, but may be associated with serious side effects such as psychotic symptoms or hypertension 3.
  • A review of long-term efficacy and safety of stimulant treatment in adult ADHD found that medication was significantly more efficacious than placebo in treating ADHD, and this favorable effect was maintained during open-label follow-up periods of up to 4 years 4.

Considerations for Long-term Treatment

  • The decision to continue or stop ADHD medication should be made on an individual basis, taking into account the need for ongoing treatment and potential side effects 5.
  • Medication-free periods should be implemented at regular times to investigate the need for ongoing benefit of medication 5.
  • Careful monitoring of side effects is necessary to detect early alarming signals 5.

Limitations of Current Evidence

  • There is limited and inconsistent evidence for long-term advantage of medication treatment beyond symptom control, such as improved social functioning, academic achievement, employment status, and less adverse psychiatric outcome 5.
  • More longitudinal studies of long duration are needed to fully understand the effects of long-term Adderall use in adults with ADHD 4.
