Frontline Plus typically has an expiration date printed on the packaging. This expiration date indicates the last day that the product is guaranteed to be effective and safe to use.
The expiration date is usually several years from the date of manufacture, as Frontline Plus is designed to remain stable and effective for an extended period when stored properly. It's important to check the expiration date before using Frontline Plus on your pet, and to avoid using any product that has expired.
Using expired Frontline Plus may reduce its effectiveness in controlling fleas and ticks, and there could be potential risks associated with using expired products. Additionally, the active ingredients in the product may degrade over time, rendering it less potent or ineffective.
If you have Frontline Plus that is expired or nearing its expiration date, it's best to dispose of it properly and purchase a new supply to ensure optimal flea and tick control for your pet.
