Because I used Interceptor for my girls, I looked into this a little...
Just spoke with customer relations rep at Novartis (800-332-2761).
She said that Excedrin and GasX products are made at the same facility as their Interceptor line. There were issues with the production of the Excedrin and GasX causing production of all items mfg'd there to be halted. She said the issues were not with their Interceptor line, and that mfg'g has resumed, but they are on back-order due to the temporary shut-down. I asked if any lots of Interceptor had been recalled... she said there are no recalls on the product line, and that production was only disrupted due to the mfg issues of the other products at the facility.
Then found this article:

Then found this one that appears to confirm what the rep at Novartis said about the problem being with Excedrin and GasX and NOT with Interceptor
