Ritalin, the attention deficit hyperactivity disorder pill, and similar medicines can cause prolonged and sometimes painful erections in rare cases, U.S. regulators warned.
Ritalin, made by Novartis AG, and other ADHD medications with the active ingredient methylphenidate also may lead to permanent penis damage, the Food and Drug Administration said in a safety communication today. The median age of patients taking the medicines who experienced the condition known as priapism was 12.5 years, the agency said.
