What additional information must be included on a label for dispensed medication according to Iowa Code?

Including the name and species of the patient on a medication label is essential for ensuring proper treatment and care. This information helps to avoid any potential medication errors by clearly identifying which animal the medication is intended for. Different species can have vastly different reactions to the same medication, and even different breeds within a species may respond differently. Therefore, specifying the patient's name and species enhances clarity and accountability in veterinary practice, ensuring that the medication is used appropriately for the intended animal.

The other options, while they may contain useful information, are not typically required on the medication label according to Iowa Code. For instance, the price paid for the medication does not directly impact the identification of the patient and is more of a transactional detail. The veterinary technician's name may not be required for the label if the prescription is issued by a veterinarian. Including the owner’s phone number, although helpful for contact purposes, does not serve the same critical role in ensuring the correct administration of the medication to the right patient.
