better attention

Up to 16 hours

post-dose, measured from 2 hours,
vs placebo in patients aged 13-17 as evaluated by PERMP1



  • Known hypersensitivity to amphetamines or other ingredients of Mydayis. Angioedema and anaphylactic reactions have been reported with other amphetamines.
  • Use with monoamine oxidase inhibitors (MAOIs) or within 14 days of last MAOI dose, due to increased risk of hypertensive crisis.

PRIMARY ENDPOINT: Adolescent patients receiving Mydayis 25 mg demonstrated significant improvement in attention compared with placebo on PERMP total score measured from 2 hours and continuing up to 16 hours post-dose.1 The post-dose average score over all testing sessions was 256 for Mydayis and 215 for placebo (P<0.0001).2

PERMP Total Score Over Time

PERMP Attention in ADHD was measured using the Permanent Product Measure of Performance (PERMP), which is a skill-adjusted math test. The PERMP score is the sum of the number of math problems attempted plus the number of math problems answered correctly in a 10-minute session. Higher scores indicate better attention.1,2
