Buying Guide
- Horse weight and dosing: Most ivermectin pastes are designed for horses up to 1,250 lbs. Always calibrate dose to weight to ensure efficacy and reduce resistance development.
- Palatability: Apple-flavored pastes and gels tend to improve acceptance. If a horse is difficult to medicate, prioritize palatable formulations or gels that reduce stress during administration.
- Parasite spectrum: Consider products that cover internal parasites common to your region, including large and small strongyles, bots, pinworms, and ascarids. Broad-spectrum options can simplify treatment plans.
- Safety considerations: Confirm pregnancy safety if breeding mares are in the program. Some products advertise pregnancy safety, but always consult a veterinarian for pregnancy-related deworming schedules.
- Administration format: Paste vs gel vs multiple-dose supplies. Gel formulas can offer cleaner administration and precise dosing, while paste products are widely used and familiar to many handlers.
- Resistance management: Rotate dewormers or use combination strategies as recommended by a veterinarian to minimize resistance; avoid over-reliance on a single active ingredient.
- Label directions and withdrawal intervals: Follow label instructions for dosing frequency, peak parasite pressure seasons, and any withholding periods if horses consume meat or enter competitions with health regulations.
- Veterinary guidance: Always coordinate parasite control programs with a veterinarian, especially for herds, breeding programs, or horses in high-parasite regions.
