Hi Marcy,
Below is an example of a recent FDA decision for an NDA product that was switched to an OTC by the innovator and therefore the associated approved ANDAs with Rx label are now considered misbranded unless they switch to the OTC versions:
Product Miralax by Bayer:
FDA has long interpreted the provisions to mean that section 503(b) of the FD&C Act does not permit the same active ingredient to be simultaneously marketed in both a prescription drug product and a nonprescription drug product, unless a meaningful difference exists between the two that makes the prescription product safe only under the supervision of a licensed practitioner."
Since FDA concluded that all of the indications the MiraLAX product met the criteria for OTC and that all of the indications were now considered to be OTC, the FDA termed this a "complete switch" rather than a partial switch, which would have had some leave behind Rx indications. In April 2007, FDA sent letters to the holders of the approved generic versions of MiraLAX explaining their position and letting them know that their products marketed with the Rx symbol would be considered misbranded, but let them know that they could submit new ANDAs for the OTC product.
As such, and with the denial of the hearing, FDA is withdrawing the approval of any of the previously approved or discontinued ANDA for the Rx versions of this product.
Hope this clarifies my previous post!

Probably withdraw from the market I.e. no more ANDAs as Rx.

Can anyone explain to me what happens to approved generic drugs when the branded drug switches from Rx to OTC. If it's a full switch, what happens to the Rx generics as the result?
Thanks so much,
Marcy
