Those with prescriptions for Adderall, the drug prescribed to treat attention deficit hyperactivity disorder (ADHD) are finding it to be increasingly more difficult to get their prescriptions full. Pharmacies around the country are running out of the drug. This shortage can be linked to abuse and because more adults and children are being diagnosed with ADHD. Some who abuse the drug are also addicted to oxycodone and when the oxycodone is not available they turn to Adderall as an alternative. Since Adderall is known as amphetamine salt, it is considered a controlled substance. The federal government controls how much is manufactured in a year. It is not known when the shortage is expected to end. See this article for how doctors and pharmacists are finding alternatives to Adderall.
