Need a fresh tube of 1.87 % ivermectin paste and wondering where to snag it fast? In the United States the cheapest, easiest places are still the big farm-supply chains. Walk into Tractor Supply Co. and the Durvet, Bimectin, or Zimecterin horse syringes sit on an open shelf for about $10–$12; the website even shows real-time stock so there’s no wasted drive. Smaller regional stores—Rural King, local co-op feed shops, tack boutiques—sell the same formula within a dollar of that price and you’ll be back in the truck in five minutes.
Prefer to order online? Valley Vet Supply and Jeffers currently list single-dose Durvet or DuraMectin tubes for $8.49–$8.99 before shipping, and orders over $75 go freight-free. Both warehouses are FDA-inspected and ship with tamper-evident lot stickers and temperature strips, which is handy if you’re building out a barn medicine kit. Chewy also stocks the major brands, but its inventory yo-yos—several SKUs show “email me when available” as of June 2025 so treat it as a fallback, not a guarantee.
Amazon Marketplace and other discount platforms do show “ivermectin paste” search results, but stick to listings that name the manufacturer, show the 1.87 % label, and ship from a U.S. address. Skip any seller bundling “human dosage charts” or advertising higher concentrations; genuine equine paste carries the “Not for human use” warning and nothing more.
A quick safety reminder: store tubes under 77 °F, purge a rice-grain line before dosing to clear air, and ask your vet for weight-specific guidance especially with foals or minis. Ivermectin paste remains over-the-counter for livestock everywhere in the U.S., but it’s not approved for self-medicating people. Buy from a feed store or a vetted vet-supply site, check the lot seal, and you’ll deworm the barn without de-worming your wallet.
