As Amalthea & CAM said; this is a common problem when dealing with GP's & Peds... since this is neither their area of expertise nor study.
((To note, however, V is Lisdexamfetamine... which is not a component in Adderal, although as an amphetamine, is in the same "family" as the dextroamphetamine that IS in Adderall. Just because it's in the same family though, doesn't *necessarily* follow that the same side effects will persist. As an example: A person can have one side effect with DrugA, but add DrugB+DrugA and they get an entirely DIFFERENT reaction. It's more likely, however that the anger reaction is tied to amphetamines as opposed to that specific type. But you would only know by trying. Neurochem is really complicatedly fun, and even experts in the field barely understand it. Essentially any time you give a patient a psychoactive drug, you're conducting a controlled experiment... hence why it's usually best to stick with someone who understands all the ins and outs of the experiment... although anyone can get "lucky" and find their personal magic wand on the first go-round.)
I would at the very least switch peds... but... if it's possible to see a psychiatrist for "med management" (aka 15 minute appointments, just like a Ped, and charged similarly) it may well be worth your time. Anger as a side effect is notoriously common to ANY of the ADHD meds, although they vary by person. I oft times think of finding the "right" adhd med, as "picking your side effects" / finding the flavor you like best. Unfortunately, a person has NO IDEA what side effects a med will give them until they've tried them... and like food... ditto won't know what "flavor" they like best until they've tried them.
http://www.drugs.com/condition/attention-deficit-disorder... has the list of the 56 most common adhd meds... in plain english as well as medicalese. (For super-medicalese click "pro")... for more info on side effects of any of the meds you have to scroll all the way to the bottom and click the link. The quick list of V's side effects don't include mood changes (although, DUH, I'm just a student and I know that by their nature ANY psychoactive drug can cause mood changes)... which is why your ped, at the "quick glance" at side effects wouldn't have seen the following (from the complete list of possible side effects) listed.
" ...new or worsening mental or mood changes; seizures; severe or persistent headache; severe or persistent irritability, nervousness,..."
But to just assume that "Gee, my patient is on a new med, and has these new symptoms... let's not make the correlation" is irritating, but very very common among those who don't work with neurochemistry on a regular basis.
