What must be specified in a veterinary prescription?

In veterinary prescriptions, it is essential to specify the species of the animal for which the drug is prescribed. This is crucial because different species may have varying responses to medications, including differences in dosage, formulation, and potential side effects. Understanding the specific animal species helps ensure that the medication is safe and effective for the intended patient, aligning treatment with veterinary standards and practices.

In the context of veterinary care, knowing the species allows the veterinarian to provide accurate dosing information and prevent potential harm from using medications intended for other species. For example, a drug that is safe for dogs may be toxic to cats, and this specificity directly affects patient safety and treatment efficacy.

The other options do not provide essential information required for a veterinary prescription. While the name of the veterinarian is required and relevant, it is not the sole requirement for a valid prescription. The cost of the drug and the previous medical history of the animal, although they may play roles in treatment plans, are not mandatory elements of a prescription itself and do not directly influence the immediate prescription needs.
