I took an old adderall (dextroamphetamine and racemic amphetamine) xr 80mg.i haven't taken it years and i want to know how long it will show up in urine. i weigh 218. how can i get it out?

Next time get Rx: It'll show up in your urine fairly quickly. Best way to "get it out" of the urine is to NOT LET IT IN without a prescription. Make sense? Don't be fooled into falling for Magnesium and antacids which are always discussed in the context of reducing tolerance to amphet's. But that doesn't necessarily make it GET OUT OF YOUR SYSTEM any faster. Just don't take it to begin with unless on doc's orders

2 1/2+ days: Adderall (dextroamphetamine and racemic amphetamine) has a half-life of 9-14hrs. It takes at least 5 half-lives to get something out of your system or 2 1/2+ days in the case of Adderall (dextroamphetamine and racemic amphetamine) (XR). Nothing else you do will speed up metabolism or get it out of your system any faster.
