How to Choose
Decision factors for selecting the right ADHD medication
First-Line Treatment
Stimulants (Adderall, Vyvanse, Concerta, Ritalin) are first-line treatment for ADHD with 75-85% response rate
Start here unless contraindications
Cardiovascular History
Non-stimulants preferred if history of heart problems, high blood pressure, or arrhythmias
Strattera, Intuniv, or Qelbree
Substance Abuse History
Non-stimulants are safer option with no abuse potential or diversion risk
Strattera or Wellbutrin
Anxiety or Tics
Stimulants may worsen anxiety or tics. Non-stimulants like Intuniv can help both
Intuniv or Strattera
Need 24/7 Coverage
Non-stimulants provide round-the-clock symptom management without rebound
Strattera, Intuniv, or Qelbree
Cost Considerations
Generic stimulants (amphetamine salts, methylphenidate) are most affordable option
Generic Adderall or Ritalin
