color of verapamil

For years I have been using verapamil HCL SR Tabs 240mg -- always a blue tablet. Today I received a prescription from my new pharmacy provider with a verapamil SR 240mg tablet (without mention of HCL on the label). It is somewhat shorter in length and WHITE in color. This the same thing as I was taking before? Or should I be concerned that there has been a mix-up

Thank you.
