New Study Raises Alarms About Generic ADHD Medications

A new peer-reviewed study in JAACAP, co-authored by Valisure scientists, reveals significant quality concerns in generic methylphenidate products used to treat ADHD.

Key findings include:

  • Nearly half of the extended-release generics tested had dissolution profiles that differed significantly from the brand-name drug.
  • A probable human carcinogen, N-nitroso-methylphenidate, was found above regulatory limits in 7 of 15 immediate-release generics.
  • Products with elevated carcinogen levels were priced similarly to safer alternatives.

The study underscores an urgent need for greater transparency in drug quality—especially when price doesn’t correlate with safety.
