Q

treatment for bullous pemphigoides

A

High-potency topical corticosteroids (eg, clobetasol 0.05% cream) should be used for localized disease and may reduce the required dose of systemic drugs.

Prednisolone (an anti inflammatory agent) and azathioprine (an immunosuppressant) can also be used in the treatment of bullous pemphigoid.

nicotinamide is used in combination with tetracycline or erythromycin to treat bullous pemphigoid

Dapsone Is particularly effective in mucous membrane lesions.
