At strong-coupling (U > W, where U is the on-site repulsion and W=8t the bandwidth) pairing is controlled by the exchange energy J=4t^2/U. One may then surmise, ignoring retardation effects, that near-neighbor Coulomb repulsion V will destroy superconductivity when it becomes larger than J, a condition that is easily satisfied in cuprates for example.
