Vyvanse

It requires around three days for Vyvanse to leave your body. If you drink extra water to flush the system it could take as little as one day to be completely removed.

That depends on the person and what effect they're looking for. Vyvanse has a longer half-life (last longer) and the desired effects are more stable throughout the effected time. Aderrall XR is less stable through it's shorter half-life; meaning that a person who is taking it can have more highs and lows throughout the effected time.

It will show up as Amphetamine (whether legal: adderall, dexedrine, and vyvanse, or illegal: speed). Unfortunately they can not tell which you took, all it is to them is "AMPHETAMINE". SO unless you have a valid prescription you should be fine (not in all cases).

I am assuming that you mean "phenteramine."

The answer is YES, both show up in drug screens. Drug screens do not test for specific drugs, only broad classes of drugs like amphetamines and benzodiazepines. Phenteramine, being a sympathetic amine of amphetamine (an "amphetamine congener") will make a drug test show up as "hot" for amphetamine. Same thing with Adderall, which is simply four different salts of amphetamine mixed together.

Hope this helps,

vyvanse ,a new pro drug that shire is marketing

Although only a doctor who is experienced with both these medications and their possible interaction effects can answer this, the general (and safer) answer would be no. First of all, there is a reason why ADHD pill containers warn users not to break the pills/chew them while taking them. This speeds their release amount per time and can have dangerous effects (such as tachycardia (too fast heartbeat), hypertension, anxiety, etc.) some of which can be life threatening. Both these drugs are stimulants, so if you take them combined, you are increasing your risks for these complications. In addition, because these work by related mechanisms, they could have combined effects that are different than either alone and more dangerous. If it is not working, the best things to try are different dose levels, different administration (for some, taking a low dose over several times a day is better than one/two normal doses), or other coping mechanisms (such as increased exercise (when NOT on the medication, i.e., at least 6 hours since you last took it (if it's not the extended release)). Also, it's possible that your symptoms may be caused by other problems than ADHD, and that is why the medication doesn't work.

Hope this answered your question. I can 99.9% guarantee you that no qualified doctor would ever recommend double doses, as it could kill you.

U will feel really wired and would be really concentrated, u also kinda feel like smoking a whole plant of cali tree

48 hours depending on how much taken

Vyvanse (lisdexamfetamine) is an inactive prodrug to Dextro-amphetamine that's broken down in the digestive tract somewhere into Levo-lysine (the AA) and Dextro-amphetamine.

About 50% of the active compounds in Adderall are Dextro-amphetamine salts, the other half being two racemic amphetamine salts. So, Adderall consists of roughly 75% Dextro-amphetamine, the ultimate active metabolite of lisdexamfetamine, and 25% Levo-amphetamine.

There are also differences in their pharmacokinetics. Adderall comes in immediate and extended release formulas. Vyvanse has a very long effetcs duration, longer then the extended release Adderall. I would take Vyvanse in the morning and always be good for the rest of the day, while the Adderall XRs wore off earlier.

$15-20 per pill. its usually 50cents per mg

I do, and so far so good, I would like to know if it has any interactions, though, I am not being very smart about it for not knowing first. IMHO, I think the Vyvanse is bad for an adult if used long term, I think it would have to start messing with the ole ticker. If you had to give one of the two up, I would quit the Vyvanse. There are about 1,000 years of history with the other, not so much, for this here cocktail of God knows what. However, no doctor will tell you that, they seem to all personally benefit from specifying brands. I bet a lot of them go home to a little bag of sunshine every night and never touch any other meds...

Yes, this should not prevent one from becoming a police officer...assuming that the person applying is upfront regarding the condition that he/she is receiving the medication for.

go for a long run and drink a lot of water.

I've lost 40 pounds doing literally nothing but sit and play video games for around 2 months. I take adderall. Some days I eat as little as 600 calories because I just don't feel like eating.

No, but they will test for the broader category of amphetamines, and both Aderrall and Vyvanse will result in a positive amphetamine result on a drug test.

Yes. It can get you high because it is a stimulant.

Yes. Vyvanse has been clinically proven to be effective in treating individuals with inattention or hyperactive subtypes of ADHD. Vyvanse is the brand name for lisdexamfetamine; this is a pro-drug for dextroamphetamine. Dextroamphetamine has been used for years in treatment of ADHD. Vyvanse is only digestable through the liver which allows the drug to last longer (providing more hours through the day) and come on smoother (which makes it less abusable).
