What is a labeling requirement for compounded preparations?

Compounded preparations are subject to specific labeling requirements to ensure safety and efficacy for patients. The correct answer emphasizes that the label must include a list of all active ingredients and their respective strengths. This information is crucial for several reasons:

1. Patient Safety: Knowing the exact composition of a compounded preparation helps healthcare providers and patients identify potential allergens or interactions with other medications.

2. Dosage Accuracy: Specifying the strength of each active ingredient aids in ensuring that the dosage is appropriate for the intended use, which is especially important in customized therapy where standard formulations do not apply.

3. Regulatory Compliance: Compounding pharmacies must adhere to regulations set forth by entities such as the FDA and state pharmacy boards. These regulations include proper labeling to assure quality control and accountability in compounded products.

The other options lack comprehensive requirements that align with industry standards for labeling compounded preparations, thus making them inadequate compared to the selection focusing on the inclusion of both active ingredients and their strengths.
