How do I apply Cheristin to my cat?
Cheristin is a quick-drying, topical solution that isn't greasy or messy. It has a rounded applicator that makes it easy to apply and comfortable for your cat. Cheristin is only for cats and kittens eight weeks of age or older and weighing 1.8 pounds or more. Always read, understand and follow the label and use directions.
HOW TO APPLY:
- Remove one applicator tube from its packaging.
- Hold the applicator tube in an upright position.
- Press the cap down and listen for a "click" that indicates the tube has been punctured.
- Hold upright and remove the cap. Check to be sure there is an opening at the tip of the tube.
- Part the hair on your cat's neck at the base of the head until skin is visible. Place the open tip of the tube directly above the skin and squeeze the tube 2-4 times to expel the contents directly on the skin.
- Discard the empty applicator tube in the trash.
We recommend applying Cheristin monthly. For best results, apply at the base of the head—not between the shoulder blades—to minimize the chances of your cat licking the product. Avoid getting the product in your cat's eyes or mouth.
Can Cheristin be administered to large and small cats?
Cheristin is a low-volume, one-size-fits-all solution for cats and kittens 8 weeks of age or older and 1.8 pounds or greater, which makes it ideal for families with multiple cats.
Does seeing fleas on my cat mean that Cheristin isn't working?
Not at all. Cheristin kills adult fleas in 30 minutes after contact. If you see fleas on your cat, they are most likely new adult fleas that will die very quickly.
If there are any fleas in your cat's environment, it can take weeks or even months for flea larvae to emerge and grow into adults. Cheristin kills adult fleas before they can lay eggs, breaking the flea lifecycle.
All cats in the household should be treated with an approved flea protection product to minimize the likelihood of flea reinfestation. It may also be necessary to apply an approved flea treatment product to your carpet and furniture in an attempt to remove the presence of fleas in your cat's environment. Low-volume dosage is one-size-fits-all for cats or kittens 8 weeks of age and older that weigh 1.8 pounds or greater. Maintain consistent monthly application of Cheristin to provide continual flea protection for your cat and prevent future infestations.
Will one tube of Cheristin be enough if my cat is over 20 pounds?
Yes. Effectiveness studies have demonstrated that a single tube of Cheristin topical solution is appropriate for, and welltolerated by, cats and kittens 8 weeks of age and older that weigh 1.8 pounds or greater.
Can I split one tube or application of Cheristin between two cats?
No. Giving a partial dose should not be done and is inconsistent with product labeling. Cheristin is one-size-fits-all solution that's ideal for families with multiple cats. Since its low-volume dose is gentle enough for all cats and kittens 8 weeks of age and older that weigh 1.8 pounds or greater, you'll want to be sure to apply an entire single dose to each of your cats.
Why can't Cheristin be used on both dogs and cats?
Cheristin is not approved for use in dogs. Dogs and cats respond to medications differently. Cheristin is specifically designed for cats with an ingredient not found in other flea solutions. Cheristin has been rigorously tested and approved by the EPA for use specifically on cats. I have multiple cats that lick each other.
Is it a problem if they groom each other after treatment?
In multiple cat households, do not allow the cats to groom each other until the product has dried.
Can I combine Cheristin with any other flea and tick products?
There are no known interactions between Cheristin and any EPA-registered or FDA-approved flea control (treatment) product for cats at labeled dosages. Please consult with your veterinarian if you have questions about medications that you are using on your cat. Is Cheristin safe to use with other medications? While there are no known medication interactions with Cheristin, it's important to discuss all of your cat's current medications with your veterinarian.
How many applications of Cheristin are in each box?
Cheristin is available in 1-, 3- and 6-dose packages. What are the potential side effects of Cheristin? Side effects may include application site reactions such as hair loss, hair change (greasy, clumping or matting) or redness, inflammation and itching. Other side effects such as inactivity, vomiting and loss of appetite have also been reported. View product label for complete safety information and always talk with your veterinarian.
