Seresto® for cats

There is no expiration date required on the packaging by the EPA for Seresto® for cats. The product should be kept in its original packaging and stored as directed on the label.

How to apply the Seresto® collar on your cat:

1. Remove the collar from its packaging.
2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain.
3. Insert the end of the collar through the buckle and loops.
4. Adjust the collar around your cat's neck until it fits comfortably on them.
5. Two fingers should fit beneath the collar and neck to ensure it is not too tight. Any excess length of the collar beyond an inch past the loops should be cut off unless it is on a growing kitten, where some additional length may be needed for adjustment as the kitten grows. Also, make sure the collar cannot be pulled over the head.
6. Check periodically and adjust fit if necessary, especially if you have a kitten that is rapidly growing.
7. Seresto® comes with three optional reflector clips that can be attached to the collar to help keep your cat visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

How to take the Seresto® collar off your cat:

Squeeze the outer sides of the buckle while pulling from the other end or side of the collar. Some may find it just as easy to cut the collar off before applying the new Seresto® collar.

Seresto^® kills fleas and ticks.

Seresto^® was designed with specific ingredients at doses that are active against fleas and ticks. Studies show that fleas and ticks are highly susceptible to the combination of imidacloprid and flumethrin found in Seresto^®.

The Seresto^® collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your dog. The active ingredients in Seresto^® are released in low concentrations from within the collar. As the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. Imidacloprid has been used in products for years to control flea infestations. Flumethrin effectively kills and repels ticks.

It’s crucial that pet owners purchase real and genuine Seresto® products from authorized veterinary clinics and trusted retailers to help ensure product authenticity and performance.

There is no evidence in the scientific evaluation conducted for registration or the regularly reviewed pharmacovigilance data to suggest a recall of Seresto® is warranted, nor has one been requested, or even suggested by any regulatory agency. As a result, Elanco continues to stand behind the safety profile of Seresto®. It remains available to consumers as an effective way to protect pets against fleas and ticks that can transmit disease and can impact their quality of life.
