Triple-bead delivery for extended release1
For adult patients, the recommended starting dose of Mydayis is 12.5 mg once daily in the morning upon awakening. Initial doses of 25 mg once daily may be considered for some adult patients. Dosage may be adjusted in increments of 12.5 mg, no sooner than weekly, up to a max 50 mg/day, based on therapeutic needs and response of the patient. Doses above 50 mg/day have shown no additional clinically meaningful benefit.
For pediatric patients (ages 13-17 years), the recommended starting dose is 12.5 mg once daily in the morning upon awakening. Dosage may be adjusted in increments of 12.5 mg, no sooner than weekly, up to recommended max dose 25 mg/day. Dose should be individualized according to the needs and response of the patient. Doses higher than 25 mg have not been evaluated in clinical trials in pediatric patients.
Pharmacological treatment of ADHD may be needed for an extended period. Periodically re-evaluate the long-term use of Mydayis and adjust dosage as needed.
Take Mydayis by mouth once daily in the morning upon awakening due to potential for insomnia and because effects may last up to 16 hours post-dose. In the event of a missed dose, do not administer later in the day. Do not administer additional medication to make up for the missed dose.

Capsule may be taken with or without food but should be taken the same way each time. Capsule may be swallowed whole or opened and sprinkled entirely on a spoonful of applesauce.
