Acetaminophen (Tylenol) can be administered to manage fever and discomfort associated with chickenpox. This is supportive care, which is the mainstay of treatment. C. Retapamulin (Altabax) is a topical antibiotic used for bacterial skin infections, not viral infections like chickenpox. D. Hydrocortisone cream is generally not recommended for chickenpox lesions due to the risk of secondary infection; soothing measures like calamine lotion or oatmeal baths are preferred for pruritus.
