What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

  • Product Details


    A healthy cat will have a healthy coat, but all that fur all over the feline allows fleas to hide themselves from view and get up to all the no-good biting behavior that makes them public enemy number one for pets. Going through all that fur with a flea comb is going to be way too time consuming and not nearly effective enough for killing fleas on cats, so it’s best to use a cat flea medication like Cheristin. One application gives your pet a full month of flea protection for cats, and within 12 hours of applying Cheristin nearly all of the fleas on your cat will have been eliminated.


    1. Hold applicator tube steady in hands and facing up.
    2. Press the cap down until you hear a click, which will break the seal and allow solution to come out of the applicator tip.
    3. Part the fur at the base of your cat’s skull and apply the entire contents of the applicator onto the exposed skin. Medication should be allowed to be absorbed into the skin naturally. Do not rub or touch the treatment area.

    Keep the treated area dry for at least 4 hours.

    Repeat once every month for effective flea prevention for cats.


    The active ingredient in Cheristin for cats topical flea treatment is Spinetoram.


    Never exceed dosage guideline – cats can only have one application per month. Speak with your veterinarian again if you feel the medication is not working well enough.

    For cats 8 weeks of age and up, and animal must weigh at least 1.8lbs.

    For topical use only, and not to be ingested orally. Only use with breeding, pregnant, or lactating cats if a veterinarian approves treatment this way for your cat.

    Harmful if swallowed. Keep away from eyes, ears, nose, and mouth.


    There are no established drug interaction risks between Cheristin for cats flea preventative and other Rx pet medications. It is advisable to always tell your veterinarian about all medications your pet is currently taking before getting a prescription and proceeding to buy Cheristin for cats.

    Side Effects

    Cheristin for cats side effects are rare, but some cats may have application site hair loss, hair change (greasy, clumping or matting), skin irritation, inactivity, vomiting, or loss of appetite. If these Cheristin for cats side effects are observed then discontinue use and consult with a veterinarian again for other flea prevention for cats solutions.
