Diclacox is indicated for the treatment of coccidiosis in chicken caused by Eimeria tenella, E. necatrix, E. brunetti, E. acervulina, E. mitis (mivati), and E. maxima. Diclacox liquid reduces the damage and lesion scores of Coccidia and improves the performance and health of infected animals. Diclazuril, the active ingredient of Diclacox, is a benzeneacetonitrile derivative. Its effect on the asexual and sexual stages of coccidia blocks the excretion of oocysts inducing an interruption of the life cycle of the parasite. Diclazuril was shown in studies to reduce lesions scores and improve the performance and health of birds challenged with E. maxima
