A member asked:
I accidentally took my son's focalin (dexmethylphenidate) 20 mg xr, will it show up on a hair folical test?
A doctor has provided 1 answer
Drug testing : Hair follicle testing will detect the drug within 5-10 days and for up to 90 days. When you have your test make sure they are aware of your situation. Take in your son's prescription. All the best.
