Tsallis-$q$ entanglement is a bipartite entanglement measure which is the generalization of entanglement of formation for $q$ tending to 1. We first expanded the range of $q$ for the analytic formula of Tsallis-\emph{q} entanglement. For $0.7 \leq \emph{q} \leq 4.3$, we proved the monogamy relation in terms of the squared Tsallis-$q$ entanglement for an arbitrary multi-qubit systems. We also showed that the $\mu$-th power of Tsallis-\emph{q} entanglement satisfies the monogamy or polygamy inequalities for any three-qubit state.
