Centragard is an FDA-approved preparation containing Centragard, for veterinary use. Available by prescription.
Veterinarians most commonly consider Centragard® for patients presented with risks associated with heartworm disease, hookworms, roundworms and tapeworms. It is frequently a point of discussion for cats with outdoor access or those residing in geographic regions with high mosquito and flea pressure. By delivering a combination of ingredients through a localized dermal application, your veterinarian can manage the risk of multiple infestations simultaneously without the need for oral administration.
At a pharmacological level, this medication functions through the complementary actions of eprinomectin, praziquantel and moxidectin. Eprinomectin and moxidectin are macrocyclic lactones that act by binding selectively to glutamate-gated chloride ion channels. This action help address the transmission of nerve impulses in susceptible nematodes, leading to paralysis and elimination of parasites such as roundworms, hookworms and heartworm larvae. Praziquantel, a pyrazineisoquinoline derivative, acts by affecting the permeability of the parasite's cell membrane to calcium ions, causing severe muscle spasms and the detachment of tapeworms from the host tissue. Your veterinarian will determine the clinical appropriateness of this medication based on your cat’s age, weight and the specific parasite challenges prevalent in your environment.

Commonly observed effects following the administration of Centragard® include localized skin reactions at the application site, such as temporary hair loss, redness or itching. Some cats may exhibit behavioral shifts including lethargy or digestive changes like vomiting or salivation, particularly if the medication is ingested through grooming. Because Centragard® contains agents discussed in the context of heartworm management, your veterinarian will prioritize a heartworm test before prescribing this prescription, as the physiological response to the elimination of larvae in heartworm-positive cats requires specialized monitoring.
This medication is typically used with caution in cats presented with severe debilitation or those with a known history of sensitivity to macrocyclic lactones. It is formulated exclusively for topical use and should not be administered orally or to other species. Owners should monitor the application site for any persistent irritation and contact their veterinarian promptly with any concerns regarding their cat’s behavior or appetite. Your veterinarian is the right person to provide guidance on the necessary duration of use and to ensure the administration protocol is appropriately tailored to your cat's individual health status.
Yes. Centragard® is a prescription-only medication and can only be dispensed by a licensed pharmacy upon receipt of a valid authorization from a licensed veterinarian. Mixlab verifies all veterinarian-client-patient relationships before any medication is prepared or shipped to your home.
Centragard® is a proprietary commercial topical solution designed for precise dosing based on the active ingredients' stability in the manufacturer's applicator. While Mixlab specializes in compounding many medications, this specific combination is typically dispensed in its original commercial format to ensure the integrity of the long-acting formula.
Veterinarians often discuss Centragard® because it includes praziquantel, an ingredient specifically considered for the management of tapeworm populations. This makes it a comprehensive option for owners looking to address both common intestinal worms and heartworm larvae in a single application.
Veterinarians most commonly discuss a monthly administration schedule to ensure continuous management of parasite risks. Your veterinarian will determine the most appropriate protocol for your pet based on their lifestyle and the specific environmental risks in your geographic area.
