There are several views when it comes to whether or not expired Vyvanse works. The general belief is that expired Vyvanse, like most expired medications, will work the same for at least a few years. Whereas, some believe that after expiry, Vyvanse may lose its potency and effectiveness rather more quickly.
What you can take from this is that Vyvanse may no longer work the same as it did before expiry. For example, if Vyvanse worked for 8 hours or stayed in the system 8 hours after taking it, then after it expires, it might only be effective for only 5 hours, or less than the usual 8 hours.

So, taking expired Vyvanse has high possibilities not to work as intended, work very slow, or even end up not working or activating within the system, when its potency reduces after expiry. Since expired Vyvanse may not work as effectively after the expiration date, there are high possibilities for users to overdose on this medication. As a controlled substance, there is a certain ingredient in Vyvanse that makes it extremely dangerous for it to be excessively consumed.
