I Have Been Taking Bystolic 20 MG For A Long

I have been taking Bystolic 20 MG for a long time. When I reordered this medication from Express Scripts, my maintenance drug supplier, I was told that the manufacturer was no longer making this drug and that it was no longer available.

Is this true? or is Express Scripts not telling the truth.

Is Forest Pharmaceuticals. Inc. the one and only distributor in the U S A ?

Thank you for your time.
