Subchronic toxicity studies of fenbendazole in rats.
The effects of prolonged exposure of rats to fenbendazole were investigated. Fenbendazole was given daily by gavage for 14 consecutive days. These dosages (3000, 500 or 50 mg/kg/d) produced reductions in body weight gains. Renal tubular hyperemia or hemorrhage and glomerular capsule dilation, increased serum creatinine and hepatocellular granular degeneration occurred at dosages of 500 and 3000 mg/kg/d. Renal tubular epithelial cell granular degeneration and tubular dilation, increased serum glutamic pyruvic transaminase, cardiac hemorrhage and granular degeneration also occurred at 3000 mg/kg/d.
