How it works
TenexMaxalt
Tenex (Guanfacine) is a centrally-acting alpha agonist medication. It lowers blood pressure by slowing down the heart rate and relaxing the blood vessels. It's not clear how Tenex (Guanfacine) works in ADHD, but it's used when stimulants haven't worked or can't be used in people.Maxalt (Rizatriptan) is a triptan medication that treats migraine headaches. It releases serotonin, which lowers the inflammation that causes headaches.

Upsides and benefits
TenexMaxalt
  • 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.
  • Triptans like Maxalt (Rizatriptan) are considered the first-choice treatment to relieve moderate to severe migraine-type headaches.
  • It can also be used to treat tension-type headaches.
  • Not all triptans work the same way for people, so you can try multiple ones to find the right medication for you.
  • You don't need to drink water with the orally disintegrating tablet for it to work, so this could be a good medication for people who can't keep water down when they have a migraine.
Downsides and risks
TenexMaxalt
  • 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.
  • Maxalt (Rizatriptan) doesn’t prevent migraines or tension headaches, but only works once the headache starts.
  • It can cause rebound headaches if it’s used too often.
  • You need to wait at least 2 hours after your first dose to take a second dose.
  • May not be the best choice if you have long, drawn-out headaches. Ask your doctor about other triptans that can last longer than Maxalt (Rizatriptan).
  • Not a good choice if you have heart disease or if you’re pregnant or breast-feeding.
