The best care practice is to start stimulants at the lowest dose and only increase if and when needed until finding the right dosage. The lowest dose of Adderall XR is 10 mg. Could be that you simply jumped in too high. Or it could be that this isn’t the right medication for you. There are two types of stimulants: amphetamine (Adderall, Vyvanse, Evekeo…) and methylphenidate (Ritalin, Concerta, Quillivant…). Almost everyone does well on one type or the other, but not both.So, this could be the wrong amphetamine type or it could be that you’d do better on methylphenidates. You definitely need to discuss what you’re experiencing with your prescribing doctor.
