It has been used to treat chronic psoriasis vulgaris^[1] and non-infected acute eczematous dermatoses (eczema).^[2] One study demonstrated that 0.05% halometasone cream was more effective than 0.05% betamethasone cream in treating dermatitis, though both were well tolerated, with no systemic adverse effects reported.^[3]
