Talk to doctor: While most of Vyvanse (lisdexamfetamine) is eliminated from the body in about 8 hours (varies with the individual), a small amount takes longer to be metabolized and may cause difficulty falling asleep.

Options may be to lower the dose, take earlier in the morning or try a shorter-acting stimulant. Good luck. ...Read more

Hello Dr. I have a question about Vyvanse (lisdexamfetamine). Is there anything I can do to rid of the amphetamine in my system/urine faster? Drinks? Food? Exercise?

Hello Dr. I have a question about Vyvanse (lisdexamfetamine). Is there anything I can do to rid of the amphetamine in my system/urine faster? Drinks? Food? Exercise?

No: None of those things actually have any significant effect on how most drugs are excreted from the body. Large amounts of liquid may dilute urine enough to cause a chemical to fall below the "detection threshhold" of the test, but such dilute urine itself will be detected and is considered a "failed" urine. If it's prescribed, it should not be a problem. If not, getting caught least of worries. ...Read more

My son is almost 4 and weights 30 pounds and is on vyvanse, (lisdexamfetamine) how long before I should notice a change?

Usually fast acting: The stimulant class of medication acts quickly in the system. It is not as reliant on height or weight as the individual's ability to quickly metabolize the medicine. I usually tell families to look for changes after the first 72 hours of medication use.
