Quick Facts
- Ivermectin is used to treat various parasitic infections in cats, such as ear mites and some internal parasites.
- It works by interfering with the nerve and muscle function of parasites, leading to their paralysis and death.
- Common forms include oral tablets, topical formulations, and injectables specifically for veterinary use.
- Onset of action can vary based on form and purpose; always follow veterinary guidance.
- Common side effects can include vomiting and diarrhea.
- Significant caution is advised with dosing, particularly in certain cat breeds sensitive to ivermectin.
- Important interactions include some antiparasitic drugs and heartworm preventatives.
- Always consult with a veterinarian regarding special populations, such as pregnant or lactating cats.
- Seek urgent veterinary help if your cat shows signs of toxicity, such as lethargy, tremors, or seizures.
What It Is and How It Works
Ivermectin is a broad-spectrum antiparasitic agent. It belongs to the avermectin class of medications and is effective against a variety of internal and external parasites. In cats, ivermectin can eliminate parasites like ear mites by disrupting their neural and muscle function, leading to paralysis and subsequent death of the parasites.
Technically, ivermectin binds to the glutamate-gated chloride channels found in invertebrate nerve and muscle cells, leading to an influx of chloride ions that paralyze and kill the parasite. This action is generally safe in mammals, as the blood-brain barrier prevents the drug from affecting CNS function. However, certain breeds or individual animals may be more susceptible due to genetics or underlying health conditions.
Indications / Uses
In cats, ivermectin is primarily used for the treatment of ear mites. It may also be employed in controlling roundworms and hookworms. While its use for some other parasitic conditions is recognized, it is crucial to follow veterinary advice, especially as incorrect use can lead to adverse effects or resistance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations suitable for cats:
- Oral Tablets: Tablets are dosed according to the cat\’s weight and the specific parasitic infection being treated.
- Topical Formulations: Spot-on solutions that are applied directly to the skin can treat external parasites like ear mites.
- Injectables: Used by veterinarians for immediate and potent parasitic control.
Dosing of ivermectin in cats must be carefully calculated based on weight, the specific parasite, and the formulation. Veterinarians consider factors such as the presence of any underlying health conditions, breed predispositions, and potential interactions with other medications the cat is taking.
How to Take It Correctly Step-by-Step
- Follow Prescription: Always adhere to the dosage and administration instructions provided by your veterinarian.
- With or without Food: Oral ivermectin can generally be given with or without food, although administration with food might reduce gastrointestinal side effects.
- Missed Dose: If a dose is missed, give it as soon as you remember. If it\’s close to the time of the next dose, skip the missed dose. Do not double-up doses.
- Storage: Store ivermectin according to the packaging guidelines, typically in a cool, dry place away from direct sunlight.
Common Mistakes: Avoid giving doses meant for other animals, and never use expired medication. Do not mix ivermectin with other treatments without veterinary approval.
