Medications Information

Fast Facts

  • 50-65% of adults with ADHD will find significant symptom relief with medication.  Another 20-30% will find that medication can substantially improve their symptoms (1)
  • Research with children suggests that the combination of lower doses of medication plus behavior training, such as CBT, may be the most effective treatment (2)
  • Research suggests that behavior modification becomes more likely when adults experience about a 50% diminishment of symptoms from their medication (3)
  • Dosage and coverage across the day are at least as important as the type of medication used.  See the effect size overview
  • Finding the right medication is a matter of experimenting under a doctor's supervision.
  • Never just use medication to manage ADHD.  Research clearly indicates this results in sub-optimal treatment.

Overview and notes

An overview of medication options and how to optimize treatment can be found in our free treatment e-book on the home page.

The Mayo Clinic overviews of individual medications are the best resource to get informed about each medication.  We include other resources as makes sense.

Finding the right medication dosage and hours of coverage, as well as type of medication, is extremely important.  Expect the process of figuring out what works for you to take some time (sometimes as long as a year or more, depending upon how often you see your doctor and how you respond.). Dr. Dodson provides a short article on the 5 mistakes providers make when prescribing ADHD meds.

Those who seem to be resistant to medications, or who wish to speed up the process of locating the best medication may wish to consider genetic testing with a product such as Genecept Assay.  This particular test looks at 18 genes that are relevant in psychiatric treatment for things such as dopamine uptake, and is administered with a cheek swab.  More details are here.

Different treatments have different effect sizes.  One reason doctor's often start with stimulant medications is that the effect size of stimulants properly dosed for a patient is, on average, higher than other options.  More information about effect size here.

Crenshaw and Daughtery's book, ADD & Zombies as a really good overview of medication management, including specifics about how different meds work and what they are good for.  Highly recommended reading for the layperson.

All medication options should be discussed with your doctor.



  • Dr. Larry Silver provides a good overview of dosing and release mechanisms, as well as what different types of medications are most useful for, and how they work in the brain.  He also talks about taking multiple drugs at the same time, in this article.
  • Good overview of basic meds that are available in Canada (and the US) - their dosing, recommendations for how to use and how to increase dosage at treatment outset to find the right dose.  From CADDRA, and updated in Jan, 2020.
