Which information must be included on drug labels that are distributed?

The inclusion of an expiration date on drug labels is essential for ensuring the safety and efficacy of medications. An expiration date indicates the time frame within which a drug is guaranteed to maintain its potency and safety when stored under the recommended conditions. Beyond this date, the manufacturer can no longer guarantee that the drug will be effective or safe to use, which is critical information for veterinary professionals and pet owners alike.

Having the expiration date readily available on the label allows veterinarians to manage inventory more effectively, preventing the administration of outdated drugs that could potentially cause harm. This information is also crucial for compliance with regulatory standards, as proper labeling is a significant part of medication management in veterinary practice.

Other options like the list of similar drugs, price of the drug, and veterinary staff history are not standard requirements for drug labels. The priority is on safety, which is why indicating the expiration date is notably critical.
