Broadline Spot-On – Flea, Tick & Heartworm Preventive for Cats

What is Broadline Spot-On?

Broadline Spot-On is a broad spectrum treatment for both internal and external parasites in cats. The spot-on controls fleas, ticks, intestinal worms including tapeworms and heartworms. It eliminates newly acquired fleas within 8 – 24 hours. It controls flea eggs from hatching and controls tick infestations. The topical treatment treats and controls biting lice, roundworms, hookworms and tapeworms. It treats mixed infestations in cats due to nematodes, cestodes and ectoparasites. It is easy to apply and safe to use on cats and kittens above 8 weeks of age.

How It Works?

Broadline Spot-On is all-in-one treatment designed for cats. It contains four major ingredients – Fipronil, (S)-Methoprene, Eprinomectin & Praziquantel. The ingredients work against fleas, ticks, immature heartworms and intestinal worms. Fipronil is an adulticide. It kills fleas and ticks. (s)-Methoprene is an insect growth regulator. It resists the growth of flea eggs and larvae. Praziquantel eliminates tapeworms and Eprinomectin prevents heartworm infections in cats. The single treatment of Broadline Spot-On is effective in controlling both internal and external parasites.

Please note that due to Boehringer Ingelheim’s acquisition of Merial Animal Health, the product packs may have varied manufacturer’s name according to the available stock.
