ATC code H03 Thyroid therapy is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup H03 is part of the anatomical group H Systemic hormonal preparations, excluding sex hormones and insulins.
Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QH03. National issues of the ATC classification may include additional codes not present in this list, which follows the WHO version.
