a message for everyone taking horse paste:
The most common horse ivermectin 1.87% paste sold online (including through sources like Ivermectinkart or similar suppliers for ~$10–25 per syringe or bundle) is a generic equine formulation. Exact excipients can vary slightly by brand (e.g., Durvet, DuraMectin, Bimectin, Dechra, Horse Health, or generic versions), but here are the typical inactive ingredients/excipients listed on labels and official sources:
Most Frequently Listed Excipients:
- Propylene Glycol (the main carrier/base, often ~94% of the paste)
- Carbomer homopolymer Type B (also called Carbopol 974P or similar – a gelling/thickening agent)
- Trolamine (also called Triethanolamine – used to adjust pH and form the gel)
- Titanium Dioxide (for color/opacity)
- Apple flavoring (natural or artificial, for palatability in horses)
These make up the clear or off-white gel-like paste in the standard 6.08 g syringe.
Other Possible VariationsSome formulations (especially older or different brands) may instead include:
- Corn oil or refined maize oil
- Polysorbate 80 (emulsifier)
- Colloidal anhydrous silica or fumed silica (thickener, sometimes called Aerosil)
- Other stabilizers or preservatives
