The DEA also sets limits on the active ingredients pharmaceutical companies use to make these drugs each year. ![]() Because the medications have a well-documented history of abuse and addiction, the FDA and Drug Enforcement Administration limit how many pills a pharmacy can dispense at once and how frequently patients can refill their prescriptions. Most ADHD medications fall into a class of controlled substances called central nervous system stimulants. Making more is ‘not as easy as flipping a switch’ Teva Pharmaceuticals, the country’s largest Adderall supplier, reports that issues with some of its Adderall dosages, particularly the more expensive brand-name versions of its fast-acting tablets, are now resolved but lists recovery dates for others as TBD (to be determined). Alvogen, which manufactures generic Adderall, expects its shortage to last until mid-April, according to the FDA’s database. Some drug companies now say the supply problems could last well into the spring. “There’s a spillover from people who couldn’t get Adderall and have turned to other drugs,” said Cheyette, a pediatric neurologist who treats both children and adults who have ADHD at the Palo Alto Medical Foundation.

Michael Ganio, senior director of pharmacy practice and quality at ASHP said an unexpected rise in demand was more to blame than manufacturing equipment or drug quality issues. Takeda Pharmaceuticals, which makes Vyvanse, also known as lisdexamfetamine, its generic, says there’s no shortage of that drug, but according to dozens of pharmacies reached by NBC News, Vyvanse has been on intermittent backorder for months. As of January, the American Society of Health-System Pharmacists, which tracks drug availability, reported shortages affecting nearly 40 different doses or formulations of generic Concerta, a long-acting form of methylphenidate, the drug in Ritalin. ![]()
