We find the analytical expression for the threshold intensity necessary to launch ultraslow light pulses in a metamaterial with simultaneous cubic electric and magnetic nonlinearity. The roles played by the permittivity, the permeability, the electric cubic nonlinearity, the magnetic cubic nonlinearity and the pulse duration are clearly identified and discussed.
