Explanation:

Identify the medication and its class

Using the Auxiliary Labels knowledge point

Doxycycline is a tetracycline-class antibiotic commonly prescribed for bacterial infections, acne, and malaria prophylaxis.

Analyze clinical side effects

Tetracyclines, including doxycycline, are well-known to cause phototoxicity and photosensitivity reactions.

Evaluate auxiliary label options

• "Refrigerate – do not freeze": Doxycycline oral suspension or tablets are stored at room temperature.
• "Avoid prolonged exposure to sunlight": This directly addresses the risk of severe sunburn and photosensitivity.
• "May cause drowsiness – avoid driving": Doxycycline does not typically cause drowsiness.
• "Take with food only": While it can be taken with food to decrease GI upset, it is ideally taken on an empty stomach for optimal absorption, and calcium/dairy can interfere with its absorption. Thus, "only" is incorrect.

Select the most appropriate label

The most critical safety warning among the choices is to avoid sunlight due to photosensitivity.

Answer:

• Refrigerate – do not freeze
• Avoid prolonged exposure to sunlight (Correct answer)
• May cause drowsiness – avoid driving
• Take with food only
