What It Is and How It Works
Ivermectin is an antiparasitic medication effective against a wide range of internal and external parasites. In the veterinary formulation, such as apple-flavored paste for horses, it acts by binding to glutamate-gated chloride channels found in nerve and muscle cells of invertebrates, causing paralysis and death of the parasites.
The effectiveness of ivermectin in combating parasites helps in controlling the spread of these organisms in equine populations, ultimately contributing to animal health management and welfare.
Indications / Uses
The primary approved use of ivermectin apple paste is in the treatment and control of certain parasitic infections in horses, including:
- Large and small strongyles
- Pinworms
- Roundworms
- Threadworms
- Stomach bots
While there has been interest in ivermectin for various off-label human conditions, it is crucial to approach such uses with caution and only under the direction of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available as an oral paste, often flavored like an apple to encourage administration in horses. The dosing must be tailored individually based on the animal\’s weight and the specific parasitic challenge. It is crucial to use the correct measurement and read the packaging instructions carefully.
Dosing for animals with potential sensitivities, such as certain dog breeds, should be conducted under veterinary advice to prevent adverse effects.
How to Take It Correctly Step-by-Step
- Ensure the horse\’s weight is accurately measured to calculate the correct dose.
- Adjust the syringe to the prescribed dose marked by the weight.
- Place the syringe into the horse’s mouth, aiming toward the back, and depress the plunger.
- Ensure that the paste is swallowed.
- Store remaining paste as per the packaging instructions, typically in a cool, dry place.
Never double-dose, and if a dose is missed or incorrectly given, get in touch with a veterinary professional.
