MKL has got sparse matrix-vector multiply several routines for Hermitian matrices and one of them is
call mkl_zcsrmv(transa, m, k, alpha, matdescra, val, indx, pntrb, pntre, x, beta, y)
In the case of Hermitian matrix, the first element of the parameter
CHARACTER. Array of six elements, specifies properties of the matrix used for operation.
must be H or h.
All the best
