What It Is and How It Works
Ivermectin works by interfering with the nerve and muscle function of parasites, ultimately causing paralysis and death of the parasite. It targets a broad spectrum of internal and external parasites, including worms and mites. In veterinary usage, it is an effective preventive and treatment method against heartworms and other parasites in dogs.
Indications / Uses
The primary use of ivermectin in dogs is for the prevention of heartworm disease and the treatment of other parasitic infections such as ear mites and sarcoptic mange. It can help control certain species of gastrointestinal worms. While it is available over-the-counter at some supply stores, it should be administered under veterinary guidance to ensure safety and efficacy.
Dosage Forms and Typical Dosing Considerations
Ivermectin can be found in oral tablets, chewables, and injectable forms. The accurate dosage of ivermectin depends on various factors, including the dog\’s weight, the specific infection being treated, and any underlying health conditions. Particularly in young, pregnant, or certain sensitive breeds, dosing should be carefully managed under veterinary supervision.
How to Take It Correctly Step-by-Step
- Follow the precise instructions provided by your veterinarian regarding dosage and administration.
- Administer at the same time each day, if prescribed daily.
- If a dose is missed, contact your veterinarian for advice on proper catch-up dosing.
- Store ivermectin at room temperature, away from excessive heat and moisture.
