Doramectin, sold under the brand name Dectomax among others, is a veterinary medication approved by the US Food and Drug Administration (FDA) for the treatment of parasites such as gastrointestinal roundworms, lungworms, eyeworms, grubs, sucking lice, and mange mites in cattle.[1][2] It is available as a generic medication.[3] It is available as a combination with levamisole under the brand name Valcor.[4]

It is used for the treatment and control of internal parasitosis (gastrointestinal and pulmonary nematodes), ticks and mange (and other ectoparasites). Doramectin is a derivative of avermectin. Similarly to other drugs of this family, it is produced by fermentation by selected strains of Streptomyces avermitilis followed by chemical modification.[1][2][5] Its spectrum includes: Haemonchus, Ostertagia, Trichostrongylus, Cooperia, and Oesophagostomum species and Dictyocaulus viviparus, Dermatobia hominis, Boophilus microplus, and Psoroptes bovis, among many other internal and external parasites. It is available as an injection and as a topical solution.[1][2]
