Adderall is typically marketed as a treatment for Attention Deficit Hyperactivity Disorder (ADHD). However, there are multiple off-label uses for the drug, some of which are currently not well understood. Some people use Adderall to improve their concentration and work ethic. Others use it to relieve symptoms of anxiety and depression. Adderall has also been used to treat chronic pain conditions, such as fibromyalgia and arthritis.
