You are referring to a condition which started about 3 months ago but was only diagnosed with the disease two weeks ago (is this correct?).
Treatment for pemphigus vulgaris may still definitely work depending on the presentation and current state of the person.Is there any presence of an infection like fever and joint pains?
Infection is a common sequalae of pemphigus vulgaris and when present requires immediate intervention and close management in a hospital setting. If there are no known complications and mostly skin manifestations are present , pemphigus vulgaris may be managed by giving immunosupressants and corticosteroids .It is the complications of pemphigus vulgaris( blood borne infection, pain in swallowing ,medication side effect) that the physician is usually concerned about. Oral blisters are the common presentation and this should be addressed by the physician.
I suggest that treatment be given immediately.Given that pemphigus vulgaris is an autoimmune disease, plasmapherisis may be initiated as adjunct to the medications.Plasmapheresis removes antibodies in the blood.
