Treatment of cyathostominosis
Treatment is likely to include:
• a larvicidal anthelmintic to eliminate the encysted larvae. Moxidectin (Equest) is the
treatment of choice. Ideally horses should be accurately weighed, or a weigh tape used to
avoid toxicity from overdosing thin or small horses
• fluid replacement – by mouth, stomach tube or intravenously as necessary
• codeine phosphate to control the diarrhoea
