Sentinel Flavor Tabs from Merck are an oral monthly preventive labeled for use in dogs to help protect against heartworm disease while managing flea populations. This flavored tablet combines milbemycin oxime and lufenuron and is designed for convenient, once-monthly administration.
Sentinel Flavor Tabs are indicated for the prevention of heartworm disease and the treatment and control of adult hookworms, roundworms, and whipworms. The lufenuron component prevents flea eggs from hatching, helping to break the flea life cycle when used as part of a comprehensive flea control program. This product is commonly used in dogs that require reliable internal parasite protection along with flea birth control in a single monthly tablet.
