We study analytically and numerically the interaction of vortices in current-carrying narrow superconducting strips. The characteristic time of vortex-antivortex pair annihilation and the energetic losses in the strip are evaluated as a function of the external transport current and width of the strip. The effects of an external magnetic field on the motion of a single vortex are discussed.
