What Is Ritalin?

Ritalin, one of the first so-called “study drugs,” is the common name for methylphenidate, a drug classified by the Drug Enforcement Administration (DEA) as a Schedule II substance—the same category as cocaine, morphine and amphetamines.* It is often abused by teens for its stimulant effects.

Even when prescribed, Ritalin can cause serious side effects, including nervousness, insomnia, loss of appetite, pulse changes, heart problems and weight loss. The manufacturer warns that users may become dependent on it.

As Ritalin abuse spread, many other “study drugs” like Adderall, Concerta, Metadate, Dexedrine, Focalin and Vyvanse entered the market. These drugs, also stimulants, have similar effects. By 2020, Adderall—a mix of two types of amphetamine—was abused more often than Ritalin.

The US Food and Drug Administration (FDA) has issued a public health warning that Ritalin and drugs like it may cause hallucinations, suicidal thoughts, psychotic behavior, aggression and violence.
