If you are one the people who have taken Vyvanse, appropriately acquired or otherwise, and find yourself in the position of having to submit to a urine test shortly after ingestion, then opinions vary as to how long this drug will stay in the system. Some sources say that the effects of Vyvanse appear to wane after 14 to 16 hours, but this does not mean that it had left the body. Evidence of this drug can be detectable in the urine from 1 to 3 days after taking. Another account says that Vyvanse stays in the body for 'exactly 5 days'. The different elements in Vyvanse, lisdexamfetamine and dextroamphetamine, have different elimination half lives and whereas one, lisdexamfetamine, will have a much shorter half life and will be metabolised and excreted more rapidly, the dextroamphetamine takes a fair bit longer and is detectable as an amphetamine in the urine. Lastly, if your job depends on random but regular urine tests and you are taking Vyvanse as part of your treatment, then it's best to bring proof that the medication is prescribed for you, either by way of the prescription itself, the container with pills and/or a doctor's note.
Vyvanse or lisdexamfetamine is a prescription drug used to treat attention deficit hyperactivity disorder in people from the age of 6 years old and upwards. It is administered orally in capsule form once daily, preferably in the morning to avoid the insomnia caused if taken later on in the day. It can be taken with or without food and comes in varying dosages. As Vyvanse is an amphetamine with a high potential for abuse and can be habit-forming if taken over a long period of time, it is classified as a class 2 controlled substance.
