Will Vyvanse show up in a urine drug test?

Yes; Vyvanse is a prodrug of dextroamphetamine. Vyvanse will show up as amphetamine on a urine drug test.

When i stop using Vyvanse will i gain weight?

Because Vyvanse is a medication that works the same day you take it I have gone through periods where I stopped. And I always ended up gaining weight. Not sure if the Vyvanse raised my metabolism, cut the hunger or I just had more will power on it. Likely a bit of all three.

Can Vyvanse cause leg pain and numbness?

Maybe... Im having the same experiance.. Im on 30mg day, for about 3 weeks.. All of a sudden, numbness (cold) in my left arm and leg... I dont know if its just because Im so focused on work that I dont get up from my desk for 4-6 hours at a time, or if its the drug. Ironically though, as soon as I started moving/walking around, it felt like the blood returned, and the area instantly had a rush of a warm feeling?!?!?!

Is it safe to take pain medications with Vyvanse?

Generally, no it doesn't matter if you take them together. But, it really depends on the type of pain medication that is being used. The analgesics (pain medication) category is truly massive and you would need to check with your primary healthcare provider to ensure that there are no drug to drug interactions.

If you have good response to Vyvanse does it mean you do have Adult ADHD?

No; Vyvanse contains lisdextafetamine which is a prodrug of dextroamphetamine. Amphetamines will cause a "good response" or increased feelings of well-being and focus in almost all individuals who consume it. It does not indicate that you have ADHD. Vyvanse is addictive and should be used cautiously, as it is a scheduled II drug that caries penalties for consumption without a prescription.

How much Vyvanse should you take to get high?

2 friends and I bought a pill each of vyvanse, specifically for that reason, and they did it at school, took one pill each.

like 10 seconds later after my 90 pound friend took it, she was high.

same thing with my 200 pound friend.

and me, 120 pounds, just took one this morning. and feel nothing.

maybe it's because i waited and it melted or something, but i am extremely pissed, so i recommend just taking ecstasy which is much better.

What is the street price of adderrall?

It depends on location and timing. Typically they will go for 10-15$ for a 20mg pill, during finals week in college you can expect to pay 20-25$.

Can Vyvanse cause leg pain?

Yes, I had pain in one elbow, then in knees and throughout legs and then back in alternating elbows. The pain was unrelenting and excruciating and continues 6 months after I stopped taking the drug. I am going back and forth between neurologist and rhumatologist and no avail. The pain persist as well as swelling of forearms and rash that looks like shingles but is not. The Doctors just think I am nuts but cannot explain the symptoms.

Does Vyvanse increase anxiety?

Stimulant medications, including amphetamines (i.e. Adderall, Vyvanse), do induce anxiety in some people. Other medications could be tried for treatment of ADHD if this anxiety is unbearable, or another medication could be used to treat this anxiety (i.e. a benzo or a mood stabilizer).

Does Vyvanse cause hair loss?

From my own personal experience I believe that it can, and has in my case. I am a 20 year old male college student, and I have seen the hair in the front of my head come out with disturbing frequency after a couple straight weeks on this drug. My advice is not to take it, the hair loss is actually one of the most visible and scary reasons that I'm stopping it.

Can you inject Vyvanse?

No; Vyvanse is a prodrug designed for a longer duration and to be less abusable. Vyvanse must pass through the liver (i.e, oral route) for it to convert to dextroamphetamine.

Is it ok to take Theraflu if your taking Vyvanse for adhd?

There are no known drug to drug interactions between these two medications, making them safe to take together. Make sure to contact you primary care provider prior to taking these two medications to ensure that it is safe.

Can you take melatonin while taking Vyvanse?

Yes; some research has indicated that it may in fact prevent some possible damage to dopamine receptors within the brain that amphetamine can potentially damage.

Can you take Vyvanse and robitussin together?

Yes, this is fine, as long as you're only having the prescribed dose of vyvanse and robitussin. It'd be best to take a daytime cold medicine that is caffiene-free (DayQuil) if on ADD meds.

Can you take Vyvanse and phentermine the same day but not at the same time?

These two drugs have very similar chemistry, so you're playing with overdosing. It's very much like doubling your dose of either one.

Is there any difference between the soon-to-be-generic Adderall XR and the new Vyvanse by Shire Pharmaceuticals that would justify switching to Vyvanase given that both claim to last up to 12 hours?

Vyvanase and Adderall both exert their effect in the brain through the same active chemical (dextroamphetamine). The difference between them is that they use different mechanisms for slowing the release of active drug, and that Adderall contains levoamphetamine as well and Vyvanase does not.

Having looked over the prescribing information for Vyvanase, it sounds like the time release mechanism in Vyvanase is significantly better, and therefore you should expect a smoother 12 hours of effects with fewer peaks and valleys.

Vyvanase may also have fewer side-effects than Adderall due to the absence of levoamphetamine. People's bodies differ in their response to drugs, so the only way to know which drug will work better for you is to try them both. One thing that is certain, though, is that Vyvanase will be more expensive, probably by a large margin.

How long will Vyvanse's effect last?

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

When will Mirapex become generic?

It became generic in Ontario, Canada around July, 2007.

Can you take Vyvanse and 5-htp?

Yes they can be taken one before or after the other or simultaneously. SWIM has found that 5-htp gets rid of some of the negative side effects from the vyvanse (anxiety, etc.)

What is Vyvanse?

Vyvanse is a central nervous stimulant which affects chemicals in the brain, increasing concentrations of certain neurotransmitters. Vyvanse is approved to treat ADHD in both children and adults. Vyvanse is the brand-name for lisdexamfetamine. Lisdexamfetamine is a prodrug of dextroamphetamine. Dextroamphetamine is a controlled substance in most countries and is only dispensed under the authorization of a doctor.

Dextroamphetamine works by increasing two chemicals in the brain: dopamine and norepinephrine. Both chemicals have been shown to play a role in focus and attention, and by raising these levels dextroamphetamine is able to help a person concentrate and sit still for longer periods of time.

Vyvanse carries unique properties due to being a prodrug of amphetamine. Vyvanse is inactive until an enzyme works to activate allowing a longer duration of symptom relief (up to 14 hours) and less abusable properties since it must be swallowed to become active.

Vyvanse is available in doses of 20mg, 30mg, 40mg, 50mg, 60mg, and 70mg. In Canada, Vyvanse is only available in doses of 20mg, 40mg, and 60mg.

How long does it take for antidiarrheal drug to work?

Has anyone lost weight on Vyvanse?

Yes, I have; weight lossis also seen in nearly 100% of all test subjects when the drug was being run through the FDA gauntlet.

How long after taking Vyvanse can you drink alcohol?

Alcohol and Vyvanse do NOT, I repeat, do NOT combine well.

You will feel like you just got mugged by bikers for HOURS if you do.

Wait at least 24 hours. 48 to be safe. You do not want to feel what it feels like to be on both. Trust me.
