Broadline is a veterinary medicine that contains four active substances: fipronil, (S)-methoprene, eprinomectin and praziquantel. It is available as a spot-on solution in applicators of two different strengths for use in cats of various bodyweights.
The content of one full applicator (appropriate to the cat's weight) is applied directly to the cat's skin after parting the hair, in one spot on the middle of the neck.
Broadline is used to treat cats with, or at risk of, mixed infestations by tapeworms, roundworms and external parasites (fleas and ticks). The product is to be used only when all three groups of parasites are targeted at the same time.
For external parasites, Broadline treats flea infestations and prevents new infestations for at least one month; it also prevents environmental flea contamination for over a month. It may also be used as part of a treatment strategy for flea allergy dermatitis (an allergic reaction to flea bites). It treats tick infestations and prevents new infestations for up to three weeks.
For worms, Broadline is used to treat tapeworms and gastrointestina roundworms as well as a type of worm that infests the bladder. It can also be used to prevent heartworm disease for one month.
