On a federal unit dose label, if required, which warning may appear?

• A. Warning May Be Habit Forming
• B. Keep Refrigerated
• C. Take With Food
• D. Not Applicable

Answer: (A)

Warnings on federal unit-dose labels address safety concerns, especially for drugs that can cause dependence. A statement like “Warning: May be habit forming” may appear if the medication has habit-forming potential and regulatory guidelines require a caution to staff and patients. This is why it’s the best choice: it represents a true warning that can be required when applicable. The other items are not warnings: keeping refrigerated is a storage instruction, taking with food is an administration direction, and “Not Applicable” isn’t a real label warning.
