I disagree but you must be careful with beta blockers in general. I took Adderall and then Dexidrene for 12 yrs for ADD/ADHD and the doctor once told me that if my blood pressure remained as high as it was, he would have to put me on blood pressure medication (metropolol}. Taking beta blockers while on stimulants will lower your blood pressure and pulse but it may feel like your heart is beating out of your chest {it did for me.} I would start out with small doses of beta blockers when on stimulants and see what reaction you have. Even better would be to bring it up with your doctor. I was afraid at the time that my doctor would cut me off my ADD medication because of my blood pressure but it turned out to not be the case. In fact, doctors can and will prescribe both. One is for focus and the other is for blood pressure.
