Explanation:

Analyze drug administration requirements

Using the Auxiliary Labels knowledge point

Levothyroxine (Synthroid) is a synthetic thyroid hormone used to treat hypothyroidism. To ensure optimal absorption, it must be taken consistently on an empty stomach, typically 30 to 60 minutes before breakfast with a full glass of water. Food, calcium, iron, and other medications can significantly impair its absorption in the gastrointestinal tract.

Evaluate the given options

• "Avoid prolonged exposure to sunlight.": This is typically used for photosensitizing medications (e.g., tetracyclines, sulfonamides).
• "Keep refrigerated.": Levothyroxine tablets are stored at room temperature.
• "May cause drowsiness.": Levothyroxine does not cause drowsiness; it is a thyroid hormone replacement.
• "Take on an empty stomach.": This is the correct auxiliary label to ensure proper absorption of levothyroxine.

Answer:

• "Avoid prolonged exposure to sunlight."
• "Keep refrigerated."
• "May cause drowsiness."
• "Take on an empty stomach." (Correct answer)
