Whereas QCD corrections to top-antitop production from e+e- annihilation at energies close to threshold have been extensively studied in the last years, a systematic treatment of the effects due to the top quark instability has not been undertaken until recently. In this talk I will review the status of the electroweak corrections to the top pair production cross section and explain how these effects can be described within an extended non-relativistic effective theory formalism for unstable particles.
