Yes, QuilliChew ER (methylphenidate HCl) is schedule II controlled substance, meaning it has a high potential for abuse.

QuilliChew ER is a central nervous system (CNS) stimulant that contains methylphenidate, which is a commonly used medication for attention deficit hyperactivity disorder (ADHD). QuilliChew ER is available only by prescription from your doctor.

Pfizer currently manufactures two different methylphenidate products for the treatment of attention deficit hyperactivity disorder (ADHD) in patients 6 years old and above – liquid Quillivant XR and QuilliChew ER chewable tablets.
