Thanks for the clarification.
Well, you see the present symptoms that your son is currently suffering from are most probably the Extrapyramidal side effects / symptoms ( EPS ) of Anti psychotics like Risperidone , and in such a circumstance , i will suggest you that you ask your son's psychiatrist to bring him off Risperidone , in fact it will be better that he comes off both the medications -- Rispredal AND Adderall ,although adderall has no role to play in this , but we need to keep your son drug free , and once the symptoms subside , then he should be re- started on ADDERALL first on a low dose and then gradually increasing to the desired dose , but refrain from starting on risperidone .
I am mentioning below a link which will throw more light on Extra pyramidal SYMPTOMS of Risperidone , an anti psychotic .
SO, I SUGEGST THAT YOU CONSULT YOUR SON'S DOCTOR AS SOON AS POSSIBLE AND ASK HIM TO BRING YOUR SON OFF FROM RISPERDAL and ADDERALL , AND WAIT TILL THE SYMTPOMS SUBSIDE , TO RESTART ADERALL. In such a situation of EPS , benzodiazepines such as Klonopin or ativan may help to improve symptoms , but the primary mode of treatment to stop all drugs and keep the patient drug free and wait for symptoms to subside, if this does not help only then benzodiazepiens or anti cholinergic drugs shall be used .
I wish your son rapid recovery to the best of health. God bless...
I hope my answer serves your query according to your satisfaction.
