Two kinds of therapists warrant special note: psychiatrists and clinical social workers. Psychiatrists are medical doctors and can prescribe medication. Clinical social workers are trained in client-centered advocacy and can assist you with information, referral, and direct help in dealing with local, State, or Federal government agencies. As a result, they often serve as case managers to help people “navigate the system.” Clinical social workers and many other mental health professionals cannot write prescriptions. However, nurse practitioners that specialize in psychiatry and mental health can prescribe medication in most states.
