Final answer:
The Rx label warning statement is not required for non-prescription drugs.
Step-by-step explanation:
In medicine, the Rx label warning statement is not required when the medication is not a prescription drug. Prescription drugs are medications that can only be obtained with a prescription from a licensed healthcare provider. If a medication is available over-the-counter or as a non-prescription drug, it does not require the Rx label warning statement.
For example, common over-the-counter medications like acetaminophen or ibuprofen do not require the Rx label warning statement.
Therefore, the Rx label warning statement is not required for non-prescription drugs.
