My pharmacist at Walgreens told me there is a shortage of Sotalol 120 is that true?

I was told the same thing at Target

2/28/12 I was just told the same thing by Walgreens, Costco, and HEB. They all say it is a manufacturer's shortage, but no one seems to know why. Looks like I'll have to start taking something else, and the sotalol was working so well for me.
