  • In many Spanish-speaking countries, the term desparasitante is used for humans as well as animals. It is common to hear doctors suggest a desparasitación as a routine preventive health measure for the whole family.
  • In some Latin American cultures, there is a traditional belief that desparasitantes can help treat vague symptoms like irritability or lack of appetite in children. This led to the common folk phrase está con parásitos to explain behavioral changes.
