My husband ordered this Ivermectin and the tube is much thicker than what I’ve previously used. Also, it doesn’t say 1.87% anywhere on the box/tube. Is this the right stuff?

Veterinarian here...this is not the same active ingredient as ivermectin. While it works similarly, they are two separate compounds.They are both broad spectrum anti-parastics, meaning that they do kill a wide array of parasites. With that said, ivermectin is known to be a bit more broad spectrum than pyrantel.
