When labeling homemade otitis externa medications, which detail must be included?

Including the common name and quantity of active ingredients in the labeling of homemade otitis externa medications is essential for several reasons. First, this information allows for clear identification of what active components are present in the medication, which can be critical for the clinician and the pet owner to understand the therapeutic purpose and potential side effects.

Additionally, specifying the quantity of active ingredients ensures that the medication is used appropriately, reducing the risk of under-dosing or overdosing the animal. This transparency in the medication's content supports safe and effective treatment, which is vital in veterinary practice. By including this detail, the practitioner also facilitates better communication and understanding between themselves, the client, and anyone else who may handle the medication.

The other options, while relevant in some contexts, do not provide the same level of essential information required for clinical safety and effective use of the medication.
