Quick Facts
- Used to control parasites in animals, especially horses.
- Works by paralysing and killing parasitic worms.
- Common form is an oral paste.
- Efficacy typically lasts for several weeks post-administration.
- Requires careful dosing based on animal weight.
- Common side effects include gastrointestinal upset.
- Pregnant or young animals may require special considerations.
- Immediate veterinary attention is needed if severe reactions occur.
What It Is and How It Works
Ivermectin paste works by interacting with the nerve and muscle cells of parasites, causing paralysis and eventually death of the parasites. This interrupts their lifecycle and helps in eliminating the parasitic infection. The medication primarily affects parasites like worms and strongyles, making it essential in veterinary medicine, especially for farm animals and horses.
Indications / Uses
Ivermectin paste is primarily used to treat and control parasitic infections in animals, including:
- Large and small strongyles (Strongyloides spp.)
- Roundworms (Parascara equorum)
- Pinworms (Oxyuris equi)
- Strongyloides westeri (threadworms)
It is especially valuable for horses that are kept in communal grazing environments where parasite load can be high.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available as an oral paste for easy administration in animals. It is critical to use the medication according to the animal\’s weight as overdosing or underdosing can have serious consequences. Regular dosing schedules can vary based on the environmental exposure to parasites, and should align with the veterinarian\’s guidance.
Adjustments might be required for pregnant animals or those with health concerns, so specific veterinary input is essential.
How to Take It Correctly Step-by-Step
- Weigh the animal accurately to determine the correct dose.
- Adjust the applicator on the syringe to give the appropriate dose.
- Insert the syringe into the animal\’s mouth, preferably toward the back to ensure full delivery of the paste.
- Press the plunger slowly to administer the correct dose.
- Ensure the animal swallows the paste completely and does not spit it out.
- Store remaining paste syringe properly for future use.
Avoid skipping doses and do not double-dose if one is missed without consulting a veterinarian.
Side Effects Common to Serious
Common Side Effects
These may include mild gastrointestinal distress, such as loose stools.
Less Common Side Effects
Occasionally, lethargy or decreased appetite may be observed post-administration.
Serious or Rare Side Effects
Severe side effects might include neurological symptoms such as ataxia or seizures, especially if overdosed. Immediate veterinary care is required if these occur.
Contraindications & Precautions
Ivermectin paste should be used cautiously or avoided in:
- Animals with a known allergy to ivermectin or similar drugs.
- Very young animals or those that are pregnant, as safety may vary.
- Any animal with neurological disorders.
A veterinarian must evaluate the risk for each individual animal.
Drug, Food, and Supplement Interactions
Some interactions might reduce efficacy or increase toxicity. It is crucial to inform the veterinarian of all other medications or supplements the animal is receiving. Using ivermectin concurrently with other central nervous system depressants can exacerbate nervous system effects.
