What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the avermectins class, which works by binding to glutamate-gated chloride channels prevalent in invertebrate nerve and muscle cells. This results in increased permeability of cell membranes to chloride ions, leading to paralysis and eventual death of the parasites. This mechanism effectively targets multiple parasite species without affecting the host animal.

Dechra Ivermectin Paste is primarily approved for treating various parasitic infections in horses. These include:
- Strongyles (large and small)
- Pinworms (Oxyuris sp.)
- Ascarids (Parascaris equorum)

- Threadworms (Strongyloides westeri)
- Bots (Gasterophilus spp.)

Ivermectin paste is provided in syringes for oral administration, with a typical concentration tailored to the animal\’s body weight. The paste is usually dosed at about 200 micrograms per kilogram of body weight. It is crucial to adhere strictly to dosing instructions from a veterinarian, as overdosing can be harmful. Factors influencing dosing include the horse\’s age, weight, and overall health condition.
How to Take It Correctly Step-by-Step
