There are other medications in the “amphetamine family”.
I found many listed at the following site:
Did your doctor prescribe the instant release (IR) or extended release (XR)? I know that I saw the IR listed in the shortage listing, but I don’t recall seeing the XR version there.
Besides Adderall IR or XR, there are related medications, like Vyvanse and Mydayis. Your doctor should be able to find an alternative that does not have a shortage. You can try asking your pharmacist what medications they recommend you ask your doctor to consider.
