According to the European Medicines Agency (EMA), the shelf life of Cerenia as packaged for sale is 2 years. Once the packaging is opened or the blister strip containing the tablets is broken, the shelf life of the tablets is reduced to 28 days. The EMA also states that Cerenia does not require any special storage conditions, and can be stored at room temperature in a dry place. However, it's still vital to store the medication away from direct sunlight, heat sources, and moisture, and also to keep it out of reach of kids and pets.
