"Is it safe to take a stimulant while being treated for high cholesterol and blood pressure?"
Larry Silver, M.D.
It is very unusual for someone to be diagnosed with AD/HD at age 78. I would question the diagnosis.
AD/HD is a lifelong condition, so I wonder why no one noticed your father’s symptoms until now. If his hyperactivity, inattention, or impulsivity is a recent development, the behavior probably isn’t caused by AD/HD; it’s important that his physician figure out what is causing it.
If you’re confident in the diagnosis, I share your concern about the medication. Because your father has high blood pressure, I would not be comfortable prescribing either a stimulant or a nonstimulant.
