What It Is and How It Works
Ivermectin is an antiparasitic drug that belongs to the macrocyclic lactone class. It functions by disrupting nerve and muscle function in parasites, ultimately causing paralysis and death. In dogs, it’s primarily used to control heartworm and treat mite infestations.
Indications / Uses
Major indications for ivermectin use in dogs include the treatment and prevention of heartworm disease, control of ear mites, and treatment of certain types of mange. It is sometimes used off-label under veterinary guidance to manage other parasite infestations. Dogs can often benefit from ivermectin as part of their routine parasite prevention regimen.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets, chewable tablets, and topical solutions. The dosing regimen is influenced by factors such as the dog’s weight, age, health status, and the specific condition being treated. Due to the potential for ivermectin toxicity, especially in certain breeds like Collies, dosing should be strictly followed as prescribed by a veterinarian.
How to Take It Correctly Step-by-Step
- Follow your veterinarian\’s prescription: do not alter the dosage.
- Oral forms can often be given with or without food, but following specific instructions is crucial.
- If a dose is missed, contact your veterinarian for guidance and do not double the next dose.
- Store ivermectin at room temperature, away from moisture and heat.
- Avoid sharing the medication with other pets.
Side Effects Common to Serious
Common Side Effects
Some common side effects include mild digestive issues like vomiting or diarrhea. Lethargy is also occasionally noted.
Less Common Side Effects
Less frequently, dogs may experience dizziness or loss of appetite.
Serious or Rare Side Effects
Serious side effects may include seizures, drooling, and tremors. If these occur, seek urgent veterinary care.
Contraindications & Precautions
Certain breeds like Collies and others with the MDR1 gene mutation may have increased sensitivity to ivermectin and require specific dosing adjustments. It\’s crucial for owners to inform veterinarians of any pre-existing conditions, allergies, or medications the dog might be taking in order to avoid adverse effects. Pregnant or nursing dogs should only be treated with ivermectin under the advice of a veterinarian.
Drug, Food, and Supplement Interactions
Ivermectin can interact with other medications that affect the central nervous system. It is important for pet owners to disclose all medications and supplements their dog is taking to avoid harmful interactions. Some adverse interactions can occur with sedatives, antifungal drugs, and certain other parasiticides.
Price & Availability
The price of ivermectin varies depending on form, dosage, and geographical location. Factors that can influence cost include whether it’s a generic versus a brand-name product, the size of the dose, and whether it\’s purchased through a veterinarian or a pharmacy.
