The renormalization, finiteness, and off-shellness of short distance inverse-power singular interactions are discussed. We show analytically that the renormalizability of the off-shell scattering amplitude relies completely on the corresponding on-shell amplitude without proliferation of new counterterms. We illustrate the result by complementary calculations both in coordinate as well as in momentum space in the simplest {sup 1}S{sub 0} channel for chiral np interactions including two pion exchange.
