Quick Facts

Ivermectin is an antiparasitic medication used to treat internal and external parasites in rabbits.
It works by paralyzing and killing parasites such as mites, lice, and worms.
Commonly available in oral, injectable, and topical forms.
Not all rabbits are suitable candidates for ivermectin treatment; professional veterinary advice is essential.
Potential side effects include lethargy, vomiting, and diarrhea.
Interactions with other medications can occur; disclose all treatments to your veterinarian.
Use with caution in rabbits with liver or kidney disease.
Seek immediate veterinary assistance if severe side effects or allergic reactions occur.

What It Is and How It Works

Ivermectin belongs to a class of drugs known as avermectins, which target parasites. It works by binding to glutamate-gated chloride channels, found only in invertebrates such as parasites. This binding causes increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. This mechanism makes ivermectin effective against a range of parasites without affecting the host animal, in this case, rabbits.

Indications / Uses

In rabbits, ivermectin is primarily used to treat parasitic infestations, including ear mites, fur mites, and internal worms such as pinworms. It can also be effective in controlling infestations of lice and other parasites that may affect a rabbit’s health and wellbeing. While ivermectin is a valuable tool in managing parasites, it should only be used when necessary and under the guidance of a veterinarian.

Dosage Forms and Typical Dosing Considerations

Ivermectin for rabbits is available in several forms, including oral, injectable, and topical. The choice of form depends on the specific condition being treated and the veterinarian’s preference. Dosing considerations include the rabbit’s weight, age, health status, and the type of parasite being targeted. It is crucial to follow the veterinarian’s dosing instructions carefully to avoid potential toxicity or underdosing.

How to Take It Correctly Step-by-Step

Consult your veterinarian to determine the appropriate form and dosage.
Administer the medication as prescribed, whether orally, by injection, or topically.
Ensure the rabbit consumes the full dose if given orally.
Store ivermectin as directed, typically in a cool, dry place.
Do not double doses if a dose is missed; contact your veterinarian for advice.
Avoid common mistakes such as using ivermectin meant for other species, which may be too potent.
