# Applicability of the Ito's lemma [duplicate]

Ito's lemma is used to find the stochastic process of the function of a Geometric Brownian process.

My question, is there any limitation of the kind of function that can be considered for correctly using the Ito's lemma, apart from just being continuous everywhere within the domain of the function?

Any insight will be highly helpful
