Treats ADHD and lowers blood pressure.
Our bottom line
Tenex (Guanfacine) can be used to treat both blood pressure and ADHD, but it's not recommended as a first-line treatment for either problem.
- 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.
- 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.

- This was prescribed for my son when he was about 8-10years old for Tourettes and with the thought it would supplement is ADHD med. It didn't seem effective for either for him. He was drowsy with this med.
- My son takes it in the evening. Seems to help him sleep and lessens the frequency of night terrors. Daytime he is more focused and has less frequent/severe behaviours.
