What is the main diff between adderall and lexapro. i was given one when i forgot my meds and it also helped me. is there a lesser evil between the 2?

Different Class: Lexapro is an antidepressant and Adderall is a stimulant. Hard to answer which is less evil. Lexapro probably safer overall, but with some side effects. Adderall being a stimulant has potential more serious side effects, mostly cardiac [heart] due to it's stimulant properties. There is a very narrow of conditons that would warrant Adderall, most take for ADD/ADHD and daytime sleepiness conditions.
