How long will Focalin stay in your urine?

Answer 1

Focalin XR is used as a part of treatment program to treat attention deficit hyperactivity disorder. This stays in the system for three months. So as not to fail a urine drug test, one must stop taking the drug for at least 3 months.

Answer 2

Half life is 2-4.5 hrs; 12 hr duration of effect; a study of 36 healthy adult who were given a signal dose of 18 mg where projected to have complete removal (AUCinf (ng∙h/mL)) of 41.8+/- 13.9.

Clearance to below detection level will be sooner.

Answer 3

If the drug test is for Focalin XR, then yes.

The real question is, are you taking it because it was prescribed to you or not? If not, you should be aware that, in the US, Focalin XR is a Class II controlled substance and that use without a valid prescription is illegal. Period.

If you have a prescription and you test positive within the prescribed limits, you are fine. If you don't, or you test outside of the limits, you are chopped liver, so to speak.
