Anyone know anything about shortage of NasalCrom

We use this stuff (NasalCrom) religiously for allergy symptoms. Now it appears to have disappeared. No one has it in stores - and you can’t order it online.

I’ve googled but haven’t been able to find out anything about a recall or some other warning.

Does anyone out there have any info?

Thanks.

AmericaRx claims to have it in stock.
