I am taking amphetamine salts 20mg tablets to help me stay focused. how long will this pill keep me focused from a single tablet?

Varies: I've had patients that said it seemed to last anywhere from 3 to 8 hours. There are time release versions as well as vyvanse (lisdexamfetamine) which gets metabolized to amphetamine. Work with your prescriber to find the one or combo that works best for your needs.
