INDICATION AND USAGE
Attention Deficit Hyperactivity Disorder (ADHD)
Methylphenidate HCl Extended-Release Capsules CD are indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD).
The efficacy of Methylphenidate HCl Extended-Release Capsules CD in the treatment of ADHD was established in one controlled trial of children aged 6 to 15 who met DSM-IV criteria for ADHD (see CLINICAL PHARMACOLOGY).
A diagnosis of Attention Deficit Hyperactivity Disorder (ADHD; DSM-IV) implies the presence of hyperactive-impulsive or inattentive symptoms that caused impairment and were present before age 7 years.
The symptoms must cause clinically significant impairment, e.g., in social, academic, or occupational functioning, and be present in two or more settings, e.g., school (or work) and at home.
The symptoms must not be better accounted for by another mental disorder.
For the Inattentive Type, at least six of the following symptoms must have persisted for at least 6 months: lack of attention to details/careless mistakes; lack of sustained attention; poor listener; failure to follow through on tasks; poor organization; avoids tasks requiring sustained mental effort; loses things; easily distracted; forgetful.
For the Hyperactive-Impulsive Type, at least six of the following symptoms must have persisted for at least 6 months: fidgeting/squirming; leaving seat; inappropriate running/climbing; difficulty with quiet activities; "on the go;" excessive talking; blurting answers; can't wait turn; intrusive.
The Combined Types requires both inattentive and hyperactive-impulsive criteria to be met.
Special Diagnostic Considerations
Specific etiology of this syndrome is unknown, and there is no single diagnostic test.
Adequate diagnosis requires the use not only of medical but of special psychological, educational, and social resources.
Learning may or may not be impaired.
The diagnosis must be based upon a complete history and evaluation of the child and not solely on the presence of the required number of DSM-IV characteristics.
Need For Comprehensive Treatment Program
Methylphenidate HCl Extended-Release Capsules CD is indicated as an integral part of a total treatment program for ADHD that may include other measures (psychological, educational, social) for patients with this syndrome.
Drug treatment may not be indicated for all children with this syndrome.
Stimulants are not intended for use in the child who exhibits symptoms secondary to environmental factors and/or other primary psychiatric disorders, including psychosis.
Appropriate educational placement is essential and psychosocial intervention is often helpful.
When remedial measures alone are insufficient, the decision to prescribe stimulant medication will depend upon the physician's assessment of the chronicity and severity of the child's symptoms.
Long-Term Use
The effectiveness of Methylphenidate HCl Extended-Release Capsules CD for long-term use, i.e., for more than 3 weeks, has not been systematically evaluated in controlled trials.
Therefore, the physician who elects to use Methylphenidate HCl Extended-Release Capsules CD for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION).
