Which item is not required by the basic DDA rule for OTC medications?

• A. The medication's lot number
• B. PMOF
• C. The expiration date on the packaging
• D. A pharmacy label

Answer: (A)

The basic rule for OTC meds focuses on ensuring the patient can use the product safely with clear instructions and valid shelf life. A pharmacy label is required because it provides the patient’s name, the exact drug, dosage, directions, and any warnings, making it clear how to take the medication. The expiration date on the packaging is essential because it tells you whether the product is still safe and effective to use. The lot number, however, is mainly used for manufacturing tracking and recalls rather than for everyday patient safety or use instructions, so it is not required by the basic DDA rule for OTC medications.
