Corticosteroids and steroid-sparing drugs are the usual treatments for PV, but there are several Other Treatments that can be used if these treatments fail.
These are:
Antibiotics
Antibiotics such as tetracycline, minocycline, or doxycycline, sometimes combined with nicotinamide, are occasionally used to treat PV.
DapsoneDapsone is a drug used to treat leprosy but it is also used to treat PV because of its anti-inflammatory effects. It is not known exactly how Dapsone works.
Plasmapheresis Plasmapheresis means plasma exchange and it is a way of removing PV autoantibodies from the blood (see ‘What causes pemphigus vulgaris?’). Plasmapheresis is only used for severe cases of PV. The steps to remove the autoantibodies are:
- Blood is taken out of the patient.
- The plasma, which contains the PV autoantibodies, is separated from the rest of the blood and removed.
- The remaining blood (that is now free from the PV autoantibodies) is then given back to the patient with a plasma replacement (transfusion).
Plasmapheresis treatment is only used very rarely. It is not an easy procedure for patients to undergo; it takes a lot of time and requires a lot of supervision.
Intravenous immunoglobulin (IVIg) Intravenous immunoglobulin (IVIg) is a concentrated source of antibodies given to patients.
- It is made from donated blood samples.
- It is given intravenously (into a vein through a drip) for several hours a day for 2 to 5 days every few weeks.
- It is generally only given to patients with more severe PV who have not responded to Other Treatments.
IVIg treatment is only used very rarely. It is not an easy procedure for patients to undergo; it takes a lot of time and requires a lot of supervision.
