The refusal of a parent or other person having control of a child to administer or consent to the administration of any psychotropic drug to such child shall not, in and of itself, constitute grounds for the Department of Children and Families to take such child into custody or for any court of competent jurisdiction to order that such child be taken into custody by the department, unless such refusal causes such child to be neglected or abused, as defined in § 46b-120.
