It usually takes about 1.5 to 2hrs for me to feel the slight effect of my Vyvanse. It works MUCH better if I take it with a small meal !!! It usually takes about 1.5 to 2hrs for me to feel the slight effect of my Vyvanse. It works MUCH better if I take it with a small meal !!!
Depends how much you took, if you took 70mg probably 12 hours or so but if you took a real high dose like 140mg probably 18 hours maybe a little more. A little more kick to it than 5 hour energy.
Lisdexamfetamine is a prodrug of dextroamphetamine. After oral administration,
lisdexamfetamine is rapidly absorbed from the gastrointestinal tract and
converted to dextroamphetamine, which is responsible for the drug's activity.
In 18 pediatric patients (aged 6 to 12) with ADHD, the Tmax of dextroamphetamine
was approximately 3.5 hours following single-dose oral administration of lisdexamfetamine
dimesylate either 30 mg, 50 mg, or 70 mg after an 8-hour overnight fast. The
Tmax of lisdexamfetamine was approximately 1 hour. Linear pharmacokinetics of dextroamphetamine
after single-dose oral administration of lisdexamfetamine dimesylate
was established over the dose range of 30 mg to 70 mg in children aged 6 to 12 years.
There is no unexpected accumulation of dextroamphetamine AUC at steady state in
healthy adults and no accumulation of lisdexamfetamine after once-daily dosing for
7 consecutive days.
Food does not affect the observed AUC and Cmax of dextroamphetamine in healthy
adults after single-dose oral administration of 70 mg of Vyvanse capsules but
prolongs Tmax by approximately 1 hour (from 3.8 hrs at fasted state to 4.7 hrs
after a high fat meal). After an 8-hour fast, the AUCs for dextroamphetamine
following oral administration of lisdexamfetamine dimesylate in solution and as
intact capsules were equivalent.
Weight/Dose normalized AUC and
You should start feeling it kicking in around 30 mins and full effects in 45 mins to an hour (give or take a few depending on how empty your stomach is and how quickly your body metabolizes medicine) Hope this helped :)
A few reasons: It is addictive. Do you know what Vyvanse actually is? It is a chemical that converts into speed. Not just kinda speed, full on actual speed. Dextroamphetamine, to be precise. VERY chemically similar to "meth"amphetamine. It is harsh on the mind and the body. With an up, there is a down. You will experience a "crash" later in the day, similar to that of caffeine, except many magnitudes worse. Vyvanse is notorious for destroying any and all hunger. Thirst, too. It makes it so hard to eat for 12 hours, people have to force food down. Those are just a few of the side-effects everyone has to deal with on this medicine. There are more complete lists of adverse effects and side-effects on google, should you care to look.
It is not pleasant to face someone talking to you while showing a mouth full of food. There is the chance of crumbs being expelled at you, or that the person could start to choke.
