Difference Between Adderall Er & Adderall Xr (Top voted first)

Hi, Can someone please educate me on the differences between Adderall ER as opposed to Adderall XR? I had no idea there was an ER as well as an XR until yesterday.

While you may be seeing two different medications, due to them being different doses, or being manufactured by different companies, at heart, just as Sean said, they are still the same time released formulation of Adderall (mixed Amphetamine salts). There are several abbreviations that can be used on time released prescription medications, along with XR and ER, you may also see SR, CR, TR, and others. However, they all mean the same thing, that the medication is in a time released formulation.

It is also possible to see the same exact pills, in the same exact dosage, dispensed to different people, with a different abbreviation on the label. This has happened to me and my husband, before.

Thus, there really is no difference. The pharmacy might not even use the same abbreviation on a prescription label as the manufacturer used on the original packaging, and to avoid confusion, some pharmacies try to use the same abbreviation that the patient's doctor used.

There has been some protesting going on to try to get them to start using one uniform abbreviation to avoid such confusion.

Are there any other questions I can help with?

There is no difference. XR stands for extended release, and so does ER. The terms are used interchangeably.

Ok, but they are in fact two separate medications. I did not know this until yesterday.

Thank you for clarifying that for me! I am still a little confused as my doctor prescribed me some Adderall ER, my insurance rejects it, stating they cover the IR & XR! So, can ya see why I'm confused here?
