We consider the prescription dependence of the Higgs effective potentialunder the presence of general nonminimal couplings. We evaluate the fermionloop correction to the effective action in a simplified Higgs-Yukawa modelwhose path integral measure takes simple form either in the Jordan or Einsteinframe. The resultant effective action becomes identical in both cases when weproperly take into account the quartically divergent term coming from thechange of measure. Working in the counterterm formalism, we clarify that thedifference between the prescriptions I and II comes from the counter term tocancel the logarithmic divergence. This difference can be absorbed into thechoice of tree-level potential from the infinitely many possibilities,including all the higher-dimensional terms. We also present another mechanismto obtain a flat potential by freezing the running of the effective quarticcoupling for large field values, using the nonminimal coupling in the gaugekinetic function.
