Upsides and benefits Tenex Imitrex › 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. › Comes in several forms. Ask your doctor if you should use the pill, nasal spray, patch, or injection. › A combination of forms can be used if symptoms do not improve. › The nasal spray and injectable forms work very quickly. › It's generally safe to use if you are pregnant. › Comes in a generic form, so it can be pretty cheap. Downsides and risks Tenex Imitrex › 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. › The oral and nasal versions of Imitrex (Sumatriptan) have an unpleasant after-taste. › Does not prevent migraine headaches; it only treats them once they start. › Must wait 1 hour before using second injection. › Can cause rebound (more) headaches if Imitrex (Sumatriptan) is used too often. › Need to have your blood pressure checked often, especially if you're pregnant.
