title: ATC code R06
text: # ATC code R06
  
  ATC code R06 Antihistamines for systemic use 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 R06 is part of the anatomical group R Respiratory system.
  
  Codes for veterinary use (ATCvet codes) can be created by placing the letter Q in front of the human ATC code: for example, QR06. National issues of the ATC classification may include additional codes not present in this list, which follows the WHO version.
