What It Is and How It Works
Ivermectin belongs to a class of drugs known as macrocyclic lactones. It works by binding to certain ion channels in nerve and muscle cells of parasites, causing paralysis and death of the parasitic organisms. This mechanism effectively eliminates infestations of internal parasites such as various worms and external parasites like bots.
In more technical terms, ivermectin enhances the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) or glutamate-gated chloride channels in the nerve and muscle cells of parasites, leading to an increased permeability of the cell membrane to chloride ions, hyperpolarization, and eventual paralysis and death of the parasite.
Indications / Uses
Durvet Ivermectin Horse Paste is primarily used for the prevention and treatment of parasitic infections in horses. These include:
- Large and Small Strongyles: Common intestinal worms affecting horses.
- Pinworms: Cause irritation and discomfort in horses.
- Roundworms: Affect young horses and may cause growth delays.
- Bots: External parasites that can cause gastrointestinal issues.
The product is not intended for use in animals other than horses, and its use in humans is not approved or considered safe outside of a licensed healthcare context.
Dosage Forms and Typical Dosing Considerations
Durvet Ivermectin comes as an oral paste. Each tube can treat horses up to 1,250 pounds, with the dosage tailored according to the horse\’s weight. For administration, the paste is delivered via a syringe, which ensures accurate dosing based on weight markings on the syringe.
While dosage for animals is relatively standard, use in humans requires specific dosage formulations and should only be done when monitored by a healthcare professional. Factors like weight, age, health conditions, and concurrent medications specify dosing adjustments that only a veterinarian can determine for horses.
How to Take It Correctly Step-by-Step
- Ensure the horse’s mouth is free of food material.
- Determine the correct dosage based on the horse’s weight.
- Adjust the syringe to the appropriate setting for the dose.
- Remove the cap and insert the tip of the syringe into the horse’s mouth at the side where there are no teeth.
- Depress the plunger to administer the paste, ensuring the horse swallows it to prevent spitting out.
- Store the remaining paste as per the storage instructions on the packaging.
Missed doses are less of a concern in horses than in humans, but adhering to a regular deworming schedule is crucial. Ensure storage conditions are met to maintain efficacy, typically away from extreme temperatures and direct sunlight.
Side Effects Common to Serious
Common Side Effects
In horses, side effects are uncommon but can include mild digestive upset.
Less Common Side Effects
Some horses may experience temporary lethargy post-treatment. This is typically self-resolving.
Serious or Rare Side Effects
Severe side effects may include swelling and itching, especially if a horse experiences hypersensitivity from a rapid death of large numbers of parasites. If serious side effects occur, a veterinarian should be consulted immediately. Rarely, overdose in horses can lead to neurotoxicity, seizures, or coma, necessitating urgent veterinary care.
Contraindications & Precautions
Ivermectin should not be used in horses known to be hypersensitive to it. Caution is advised with foals and very young animals or those with impaired liver function, given their potentially increased sensitivity to the drug. Pregnant mares can generally use ivermectin, but consulting a veterinarian is advised.
This product is not safe for human use unless prescribed by a healthcare provider for an approved indication. Always adhere to veterinary guidance when treating animals.
Drug, Food, and Supplement Interactions
Interactions of ivermectin with other medications in horses are rare but possible. It should not be combined with other ivermectins or similar antiparasitics without veterinary advice. Horses on concurrent medications should be monitored for adverse interactions.
Human medications can interact differently with ivermectin, underlining the need for healthcare oversight if used in such contexts.
