Correct answer: A — Follow the product-specific storage and discard-after-opening instructions

Eye drop products have specific storage requirements and in-use shelf lives to reduce contamination and preserve stability. Latanoprost commonly has refrigeration requirements before opening and product-specific storage after opening. The patient should follow the dispensed label and patient leaflet rather than appearance of the solution.
