  • Does dosage for this drug change for children?

  • How does my body process this drug?
    Adderall is well-absorbed in the gastrointestinal tract. The bioavailability is typically over 75% for dextroamphetamine. The absorption of Adderall depends upon the pH of the individual’s gastrointestinal tract. Basic pH increases its absorption through the lipid-rich cell membranes of the gut. Acidic pH changes the drug in its water soluble cationic (salt) form, and less is absorbed. The drug is metabolized in the liver which results in a variety of excreted metabolic products.
  • How can I get the most out of my treatment with this medication?
    This drug is primarily prescribed to treat ADHD, which is a condition also regularly addressed with various types of psychotherapy—most notably behavioral modification. Finding a therapist or counselor that is trained in behavioral therapy may help you better regulate your emotional and behavioral responses to symptoms associated with ADHD. Additionally, a therapist can help you develop a safe plan to gain control over symptoms, help you develop important coping strategies, and they can help you learn to stay more focused and manage impulses.
