Upsides
  • The same medication treats two different things, high blood pressure and attention deficit hyperactivity disorder (ADHD).
  • It's not a "controlled medication".
  • Used to control ADHD when stimulant medications haven't worked or can't be used due to other medical problems.
  • Available as a generic medication, so it should be more affordable than other options.

Downsides
  • Doesn't control ADHD as well as stimulants do, so it's used as a second-line medication.
  • Not a preferred drug to control blood pressure.
  • Can't be stopped suddenly, especially for blood pressure, since the blood pressure can dramatically increase.
