What is the shelf life for calamine lotion?

The shelf life of calamine lotion is typically around 3 years when stored properly, away from direct sunlight and at room temperature. Always check the expiration date printed on the packaging, as it indicates the period during which the product is guaranteed to remain effective. After the expiration date, the potency may decrease, so it's advisable to dispose of any expired lotion. If the lotion has changed in color, consistency, or smell, it’s best not to use it.
