It’s the Adderall. 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. My son had this reaction to amphetamines as well — angry, vile, aggressive, and crying a lot. Totally out of character. He handled methylphenidate much better. The prescribing doctor needs to know about this behavior.
