                                According to the manufacturer Abbott Nutrition, an opened PediaSure ready-to-drink shake should be refrigerated and used within 24 to 48 hours, depending on the specific product and how it is consumed. Proper storage is critical to maintaining the nutritional integrity and safety of the product, especially for a child's consumption.
