We demonstrate that the UV/IR mixing problems found recently for a scalar φ4 theory on the fuzzy sphere are localized to tadpole diagrams and can be overcome by a suitable modification of the action. This modification is equivalent to normal ordering the φ4 vertex. In the limit of the commutative sphere, the perturbation theory of this modified action matches that of the commutative theory. © SISSA/ISAS 2002.
