Which of the following information is not required on the formula worksheets?

The option indicating that the patient's medical history is not required on the formula worksheets is correct. In the context of pharmacy practice, particularly concerning compounding, formula worksheets are designed to capture essential information directly related to the formulation and preparation of medications. This includes the names of technicians involved, the pharmacist's initials who verified the preparation, and detailed mixing instructions, which are all critical for ensuring accuracy, accountability, and safety during the compounding process.

While understanding a patient's medical history can be important for overall treatment decisions, it is not typically documented on a formula worksheet. Instead, patient medical history is usually found in patient profiles or records, which inform medication therapy management but are separate from the details needed for creating or compounding a specific medication. Therefore, including this type of information on a formula worksheet is not required, as it could lead to unnecessary complexity and detract from the primary focus of the document.
