Specializes in Allergy and Immunology

Usually: Yes, we often treat with double the recommended daily dose of Zyrtec (cetirizine) to control hives. Would not recommend it without discussing with your physician since it is a higher dose and consideration of medication interactions and side effects is warranted.
