How is delusional parasitosis treated?

With patience & care: Delusional parasitosis is a difficult illness to treat. It can be very chronic, and there can be secondary infection from scratching and self-gauging. These need treatment by physicians too. For the anxiety, ssri's & low-dose antipsychotics are sometimes used -- also psychotherapy if the person will agree to it. The less anxiety, the less skin focus and picking, often.
