Pretreatment Screening

Prior to treating patients with QuilliChew ER, assess:

for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam).
the family history and clinically evaluate patients for motor or verbal tics or Tourette’s syndrome before initiating QuilliChew ER.

Recommended Dosage

The recommended starting dosage of QuilliChew ER for patients 6 years and above is 20 mg once daily orally in the morning. The dose may be titrated up or down weekly in increments of 10 mg, 15 mg or 20 mg. The 10 mg and 15 mg doses can each be achieved by breaking in half the functionally scored 20 mg and 30 mg tablets, respectively. Daily doses above 60 mg have not been studied and are not recommended. As with any CNS stimulant, during titration of QuilliChew ER, the prescribed dose should be adjusted, if necessary, until a well-tolerated, therapeutic dose is achieved.

Administration Instructions

QuilliChew ER should be orally administered once daily in the morning with or without food.

Switching from other Methylphenidate Products

If switching from other methylphenidate products, discontinue that treatment, and titrate with QuilliChew ER using the above titration schedule.

Do not substitute for other methylphenidate products on a milligram-per-milligram basis, because of different methylphenidate base compositions and differing pharmacokinetic profiles.

Dosage Reduction and Discontinuation

If paradoxical aggravation of symptoms or other adverse reaction occur, reduce dosage, or, if necessary, discontinue QuilliChew ER. If improvement is not observed after appropriate dosage adjustment over a one-month period, discontinue QuilliChew ER.
