Econor is an antibiotic.

It is used in pigs to treat or prevent a number of infectious diseases that are caused by bacteria and affect the lungs (i.e. swine enzootic pneumonia) or the gut (i.e. swine dysentery, porcine proliferative enteropathy or porcine colonic spirochaetosis).

Econor improves the health and reduces weight loss of the treated pigs, but may not completely eliminate the bacteria that cause lung infection.

In rabbits, Econor is used to reduce mortality during an outbreak of epizootic rabbit enteropathy (ERE). This is a disease associated with changes in the normal balance of bacteria in the gut which allow growth of clostridia, bacteria that produce a toxin which paralyses the intestine. ERE commonly occurs in commercial rabbit farms during the post-weaning fattening period.

Econor contains the active substance valnemulin.
