Ivermectin Injection for Cats: an Effective Option for Feline Care

Uses of Ivermectin Injection in Cats

In cats, Ivermectin injection is primarily used to treat:

External parasites: It is effective against fleas, ticks, and mites.

Internal parasites: It can be used to treat certain types of intestinal worms, such as roundworms and hookworms. However, the medication has been shown to be ineffective against tapeworms.

Heartworm prevention: Although less common in cats than in dogs, it can be used in specific cases.

 

Ivermectin Action Against Parasites

It impedes neurotransmission within parasites by enhancing gamma-aminobutyric acid (GABA) activity—leading them ultimately toward immobilization. While this mechanism serves well against many external parasites such as mites or lice.

 

Dosage and Administration

General Dosage: The typical dosage of ivermectin injection for cats is 0.1 to 0.2 mg/kg of body weight. However, the exact dosage may vary based on the specific condition being treated and should always be determined by a veterinarian.

Injection Site: It is often administered subcutaneously or intramuscularly. The veterinarian will decide the appropriate route based on the clinical situation.

Administration Procedure

Preparation: Ensure that the injection site is clean. Use aseptic techniques to avoid infection.

Choose the Route of Administration:

Subcutaneous (SC): This is the most common route for administering ivermectin in cats. The injection is given under the skin, usually in the scruff of the neck.

Intramuscular (IM): This route may also be used, particularly in cases where a more rapid absorption is needed.

 

Precautions

Species Sensitivity: Cats are more sensitive to ivermectin than dogs. Dosing must be carefully controlled to avoid toxicity.

Health Conditions: Cats with certain health conditions, such as liver disease or those who are pregnant, may be at higher risk for adverse effects.

Drug Interactions: Always inform your veterinarian about any other medications your cat is taking, as ivermectin can interact with certain drugs.

 

Considerations for Use

Do not use in kittens younger than 6 weeks of age.

Avoid using alongside benzodiazepines, ketamine, erythromycin, spinosad, or certain anti-fungal treatments.

 

Side Effects of Ivermectin Injection for Cats

When given correctly, ivermectin is safe for most cats. Allergies to the drug are not common but can cause adverse reactions. Ivermectin toxicity can also occur if too much of the drug is given to a cat. Cats under 1 year of age are more prone to nervous system toxicity from higher doses. Some side effects include:

‌1. Blindness:‌ Clinical signs of blindness can include cloudy eyes, uneven pupils, and bumping into objects.

2‌. Lack of coordination (also known as ataxia):‌ cats suffering from ataxia may have a wobbly gait and sway when they walk.

‌3. Lethargy:‌ When cats are lethargic, they may eat less, play less, and hide from humans with whom they are normally affectionate.

‌4. Dilated pupils (mydriasis):‌ Cats’ pupils can become dilated if they are startled by something. However, if it is ongoing, it might be a concern.

‌5. Upset stomach:‌ A cat with an upset stomach may vomit; have diarrhea; refuse to eat; or show signs of nausea, such as licking their lips.

‌6. Lack of appetite and/or thirst:‌ If a cat is eating or drinking less than usual after receiving a dose of ivermectin, it should be mentioned to the veterinarian.

‌7. Seizures:‌ Seizures cause unusual behavior, such as excessive drooling, aggressive behavior, and facial twitching.

‌8. Death:‌ In the most extreme cases, ivermectin toxicosis can lead to death if the cat is not brought to the veterinarian immediately.

Cats suffering from ivermectin toxicosis need immediate and intensive veterinary treatment.
