Hello, I’ve tried a generic Adderall XR by Teva and unfortunately it tested positive for other active ingredients that aren’t labeled as being in the medicine. So, unfortunately it left a lot to be desired. I think you might be referring to the drug company Shire? They make the original Adderall XR and now Vyvance. I fortunately haven’t had anxiety problems from stimulants. I have had badly tainted stimulants though.
If you’re new to simulants treatment let me suggest you go with a name brand if your insurance will cover it. There are a lot of sub par generics out there. Also, if it feels off or wrong, trust your feeling and if you can have the drug checked or by yourself some home urinalyses tests. I’ve found other drugs in some of my stimulants this year. There is clearly some problems in the supply chain.
