Amoxicillin in its liquid form should be kept in a refrigerator at temperatures between 2°C and 8°C (35°F and 46°F), but can also be stored at room temperature, typically between 20°C and 25°C (68°F and 77°F). Moreover, storing it in a fridge can increase tolerability, especially for children, making it taste better chilled. Dispose of any unused medication after 14 days, regardless of whether they are stored in the refrigerator or at room temperature.
