I took a drug test for probation yesterday I have a scrip for adderall ran out and took vyvanse (lisdexamfetamine) can they tell the difference on a lab tests?

No: But it is against the law to take someone else's prescrtion medication. You are still risking your parole because they can look on the state registry and find the full dates for your prescription. Be perfect with your medication. They can even ask for pill counts!! ...Read more

What is the difference between Adderall and Vyvanse (lisdexamfetamine) for add?

What is the difference between Adderall and Vyvanse (lisdexamfetamine) for add?

Delivery form: Both a amphetamine (amp). Adderall is a blend of d-amp (50%) and d, l-amp (50%). Vyvanse (lisdexamfetamine) is called a prodrug: it is d-amp linked to an amino acid. It is inactive till it gets in the body, where an enzyme cleaves the molecule, releasing d-amp. That means a very different release pattern, and it is the longest acting oral stimulant. Some like one, others the other. Both can be effective. ...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?

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 Being out of date, your case would be very weak if they wanted to be tough.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

Took 2 30mg Vyvanse (lisdexamfetamine) Sunday, 3 Tuesday & 3 Wednesday (today). Have a urine drug test in 6 days. Will the Vyvanse (lisdexamfetamine) be out of my urine within next 6 days?

Vyvanse (lisdexamfetamine) in Urine: It is important to understand that each of us metabolize and eliminate medications in our own unique way so time frames given cannot be taken as being exact and applicable to the entire population. Having said that, most patients should have no detectable amphetamine in the blood or urine five days after the last dose was taken. Remember that this applies to "general population samples." ...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

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
