I was a vet tech for seven years, up till about two years ago. At all the clinics i have worked for albon was the main txt for coccidia. Coccidia can be difficult to treat. Ivermectin is a one time dosage, but can be very dangerous if dosed incorrect. Albon is a relativly harmful drug even when overdosed. The worst an animal might get is some diarrhea from an over dose of albon.
