What must a label indicate for a preparation if it is not administered immediately after compounding?

The label for a preparation that is not administered immediately after compounding must indicate all ingredients with their amounts, as well as patient identification information. This is important for several reasons.

First, including all ingredients with their amounts ensures proper information is provided for any potential allergies or interactions. It allows healthcare providers to track what is included in the compound, which is crucial for patient safety and effective treatment.

Second, patient identification information is necessary to ensure that the preparation can be correctly matched to the right patient, avoiding medication errors that could arise from mislabeling or miscommunication.

In situations where a preparation may be stored or held for a period of time before administration, clear labeling helps maintain the integrity and efficacy of the product, safeguards against incorrect usage, and supports regulatory compliance.

The other choices do not provide comprehensive information necessary for safe administration. Focusing only on the dosage form and route does not encompass the critical details required for patient safety, while citing only the expiration date or pharmacist's signature neglects essential component details that could impact therapeutic outcomes.
