Take prescription: bottle with your name on the label with you & it won't matter. If you've been on it for more than 7- 10 days, it will show up as amphetamines/methamphetamines on a hair test. It can show up for ~ 3 days in urine, but it could be longer, depending on your weight, metabolism, etc., but there's no need to stop it as long as you take your bottle with you. ...Read more

Can a blood drug test determine how much of my.kolonopin and Vyvanse (lisdexamfetamine) I've taken all month long or is there a.detection period? Why not do a urine test

Yes: If you are taking your medicine on a consistent basis, a Steady State Serum or Blood test should provide a pretty good indication of your adherence to directions. Urine Drug testing only gives a qualitative indication of your medication taking history-in other words-yes you are taking or no you're not taking it. The blood level is an instant snapshot of your blood level so it is difficult to fool. ...Read more

Will Vyvanse (lisdexamfetamine) 30mg affect a drug test after one dose?

Yes, depending on : When testing is done relative to when it was taken. However, "drug screens" are read as positive by the concentration of a drug or its metabolite in the urine sample; therefore, depending on timing, the concentration may fall below the cut-off point for a "positive" screen. It isn't a problem for anyone who can show a prescription bottle in his or her name. Diversion is a different story. ...Read more

Is taking an old prescription (Vyvanse) legal? Could I be fired for a positive drug test, even if I have the prescription for it, though it is old?

Complicated: Yes, depending on the company's policies, you could be fired - even if the Rx was current. You'd have a good fight if it was, but you could still lose. Being out of date, your case would be very weak if they wanted to be tough. If you took it for the medical purpose, I feel bad for you but it was still a risky idea. If you took it for fun - it was more foolish. You can learn and hope for the best. ...Read more
