What It Is and How It Works
Ivermectin is an antiparasitic drug that is effective against a variety of parasitic worms and external parasites such as lice and mites. The drug works by binding to glutamate-gated chloride ion channels in the nerve and muscle cells of invertebrates. This results in increased permeability to chloride ions, leading to paralysis and death of the parasite.
While highly effective for many types of parasites, it is crucial to administer the correct dose, as certain dog breeds have a genetic mutation that makes them particularly sensitive to the drug.
Indications / Uses
Ivermectin tablets for dogs are primarily indicated for the prevention of heartworm disease and treatment of other parasitic infestations like mites and roundworms. Veterinarians may prescribe ivermectin for:
- Prevention of Heartworm Disease: Administered as part of a monthly heartworm prevention regimen.
- Treatment of Demodectic Mange: Used to address demodex mite infestations.
- Control and Treatment of Intestinal Parasites: Effective against certain types of worms.
Off-label use of ivermectin should only be considered under veterinary supervision to ensure efficacy and safety.
Dosage Forms and Typical Dosing Considerations
Ivermectin comes in several forms, including tablets, flavored chewing tabs, liquids, and topical solutions. The form and dosing schedule largely depend on the dog’s weight, the type of parasite being treated, and any concurrent medical conditions. It\’s vital for owners to follow dosing instructions provided by a veterinarian strictly, as the risk of overdose can be severe, particularly in breeds that carry the MDR1 mutation affecting drug sensitivity.
How to Take It Correctly Step-by-Step
When giving ivermectin to your dog, follow these steps:
- Administer the medication as per the veterinarian\’s instructions. Timing and whether to administer with food can depend on the specific product prescribed.
- Ensure the entire dose is swallowed; occasional dosing errors like missing a dose should be discussed with your vet.
- Store medication away from light and moisture, and keep out of reach of children and pets.
- If a dose is missed, refer to your veterinarian for advice rather than doubling the dose on the next administration.
