This tablet is manufactured by Mallinckrodt Pharmaceuticals, and they list it as containing 20mgs of Methylphenidate, a generic for Ritalin, which is most commonly used to treat ADHD, and narcolepsy. NDC: 00406-1473
The FDA warns that this medication carries the risk of being habit forming, and may cause side effects, such as nausea, dizziness, headache, irritability, insomnia, and anorexia.
