It would take just over 2 days for a dose to be out of your system. You should allow for longer (7 days) if you have taken Adderall frequently and at high doses. Continue reading

The main difference between Adderall and Vyvanse is that Adderall is a mixture of four different kinds of amphetamine salts (one of which is dextroamphetamine) while Vyvanse only contains one type of amphetamine salt, called lisdexamfetamine. Lisdexamfetamine gets converted into dexamphetamine once it is in the body. One advantage of Vyvanse is that it may be less likely to be abused; although it is slightly more expensive than Adderall, although both have generic forms available. Because both drugs contain amphetamines, they work in a similar way. Studies have shown that Vyvanse is just as effective as Adderall, and side effects, including the risk of dependence, are similar.

There is no evidence that Adderall helps with anxiety and in many people with pre-existing mood disorders, Adderall can make depression and/or anxiety worse. Continue reading
