The normal inflammatory response to local infections can be masked by halobetasol. Application of topical corticosteroids to areas of infection, including tuberculosis of the skin, dermatologic fungal infection, and cutaneous or systemic viral infection (., measles or varicella), should be initiated or continued only if the appropriate antiinfective treatment is instituted. Herpes infection may be transmitted to other sites, including the eye. If the infection does not respond to the antimicrobial therapy, the concurrent use of the topical corticosteroid should be discontinued until the infection is controlled. Topical corticosteroids may delay the healing of non-infected wounds, such as venous stasis ulcers.
