Medication Summary
Tepid baths, compresses, and emollients may help alleviate pruritus. Patients with mild disease can be treated with antihistamines and midpotency topical or intralesional steroids, such as triamcinolone. However, these are usually ineffective in more severe cases, and systemic steroids remain the mainstay of therapy. Prednisone at 0.5 mg/kg/d is usually started, and the response to therapy is gauged by the abatement of pruritus and blister formation. Once blistering has ceased and lesions have begun to heal, the dose of prednisone is tapered to the minimum dose required to control the disease. Reported steroid-sparing agents used as the adjuvant therapy in the treatment of pemphigoid gestationis include azathioprine, dapsone, methotrexate, intravenous immunoglobulin, cyclosporine, pyridoxine, plasmapheresis, and minocycline/nicotinamide. Chemical oophorectomy with goserelin (a luteinizing hormone–releasing analog) also may hold promise.
Corticosteroids
Class Summary
Corticosteroids have anti-inflammatory properties and cause profound and varied metabolic effects. In addition, they modify the body's immune response to diverse stimuli.
Triamcinolone (Aristocort)
Treats inflammatory dermatosis that is responsive to steroids. Decreases inflammation by suppressing migration of PMN leukocytes and reversing capillary permeability. Apply water-based creams sparingly and rub into skin until they disappear. Ointments, which are in a petrolatum-based vehicle, are used to treat chronic dermatoses. Use 0.1% cream or ointment.
Prednisone (Deltasone)
Immunosuppressant used for the treatment of autoimmune disorders. May decrease inflammation by reversing increased capillary permeability and suppressing PMN activity. Stabilizes lysosomal membranes and suppresses lymphocytes and antibody production. In patients with severe blistering in whom topical or intralesional steroids fail to elicit a response, oral prednisone may be indicated.
Antihistamines
Class Summary
Antihistamines prevent histamine response in sensory nerve endings and blood vessels. They are more effective in preventing histamine response than in reversing it.
Diphenhydramine (Benadryl, Belix)
For symptomatic control of severe unremitting pruritus not controlled with previous therapeutic regimens.
