small, white and round. . There is an indented line directly in the middle of the pill. On one side of this line is has 4B imprinted, on the other 11. On the opposite side of the pill it has an indented V. The V has a line going out from the top of the right line that forms the v. It looks like a mix between a V and a square root symbol. Does anyone know what this pill is? It was found in my daughters room and I can't seem to locate this particular pill.
