The FDA has confirmed the nation is experiencing a shortage of Adderall after many pharmacies around the country have been unable to fill prescriptions and keep up with demand.

The drug, which is also known as mixed amphetamine salts, is used to treat attention-deficit/hyperactivity disorder (ADHD) and narcolepsy.

“We will continue to monitor supply and assist manufacturers with anything needed to resolve the shortage and will update our website with new supply information as it becomes available,” the FDA said.
