Tips to alleviate symptoms
Antihistamines or topical calamine lotion would usually be prescribed by doctor to alleviate the itch from chickenpox. Antipyretics such as paracetamol would also be given. There is no food that parents should not give or is not suitable during a chickenpox episode. I would strongly encourage more fluids to prevent dehydration.
