Doramectin is a synthetic avermectin shown to be effective against internal and external parasites of cattle[1].

It is a macrocyclic lactone effective against gastrointestinal nematodes, lungworms, eyeworms, warbles, lice, ticks, mange mites and dung beetles[2]. It appears equally efficacious as ivermectin and moxidectin[3].

Doramectin is available as an oral or injectable formulation.

Recommended dose is 200-500 μg/kg body weight given by subcutaneous injection.

Sensitivity to avermectin B1 was reported in Murray Grey cattle.
