Contraindicated in Tortoise / Turtle

Tortoise / Turtle: Ivermectin causes fatal toxicosis in chelonians at doses other reptiles tolerateChelonians are far more sensitive than lizards and snakes: doses routine elsewhere in reptile practice have produced paralysis and death in turtles and tortoises. Do not use ivermectin in chelonians; use fenbendazole or another alternative. (The cited study did find 0.05 mg/kg IM tolerated in red-footed tortoises when not repeated inside 7 days, so the hazard is dose- and interval-dependent rather than absolute — but that margin is far too narrow to work to in a clinical setting.)
