Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder typically classified into three types based on the predominant symptoms:

  • Predominantly inattentive ADHD: Difficulty maintaining focus, following instructions, or completing tasks. 
  • Predominantly hyperactive-impulsive ADHD: Persistent restlessness, fidgeting, and impulsivity.
  • Combined ADHD: Combination of inattentive, hyperactive, and impulsive symptoms. This is the most common type of ADHD.

ADHD can be managed with psychotherapy and, in some cases, medications.

Nonstimulant ADHD meds may be effective for many people, particularly if you have difficulty tolerating the effects of stimulant medications or have the potential for developing substance use disorder.

Nonstimulant ADHD meds are second-line treatments for symptoms of all types of ADHD. As opposed to stimulants, they are not controlled substances. This means they have a lower chance of causing dependence and withdrawal symptoms.

Nonstimulant ADHD meds may take longer to work compared to the fast-acting effect of stimulants, because they have an indirect effect on brain nerve signaling.

Your healthcare professional may recommend nonstimulants over stimulant ADHD medications if you have had moderate to severe side effects with stimulants, have a history of substance use disorder, or haven’t responded to treatment with stimulant drugs.

In some cases, a healthcare professional may combine nonstimulant ADHD meds with stimulants to achieve effective symptom management.

Summary

Nonstimulant ADHD meds offer symptom relief with a lower chance of dependence and addiction. This is why they are not controlled substances. They may also lead to fewer side effects. 

Nonstimulant meds may take longer to relieve ADHD symptoms compared to stimulant medications. This is why they are often a second line of treatment. But they may be preferred by people who do not respond well to stimulants or who may have a higher chance of developing substance use disorder.

Consider talking with your healthcare professional to determine the most suitable treatment plan for managing your ADHD symptoms effectively.
