What Causes Granuloma Annulare and How is it Treated?

10. Generalized GA Treatment

Generalized forms of granuloma annulare are difficult to treat. Oral, topical, or injectable steroids are usually the first option, but steroids are most effective before the lesions spread to multiple areas. The bumps almost always return when the person stops taking steroid medication, but ongoing steroid treatment has many side effects. Phototherapy is the second most common treatment method. It involves exposing affected areas of skin to ultraviolet light. Doctors may employ UVA1 phototherapy, PUVA photochemotherapy, or photodynamic therapy.
