treat with appropriate local or systemic (eg, oral) antifungal therapy while treatment continues; at times therapy may need to be interrupted; advise patient to rinse his/her mouth with water without swallowing following administration of drug to help reduce risk of oropharyngeal candidiasis Potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex; more serious or even fatal course of chickenpox or measles in susceptible patients; use caution because of potential for worsening of these infections;
