Toltrazuril Explained

Toltrazuril is an antiparasitic medication used primarily to treat coccidiosis in animals. Coccidiosis is a parasitic disease caused by coccidia, which are microscopic, spore-forming, single-celled obligate intracellular parasites belonging to the apicomplexan class Conoidasida.[1] [2] [3]

Mechanism of action

Toltrazuril works by interfering with the protozoa's ability to reproduce. It disrupts the division of the protozoal nucleus and damages the cell membrane of the parasites. This action results in the destruction of the coccidia at all stages of their life cycle.[4]

Use in veterinary medicine

Toltrazuril is widely used in veterinary medicine to treat coccidiosis in various animals, including poultry, pigs, cattle, sheep, and companion animals like dogs and cats. It is often administered as a single dose or in a series of doses depending on the severity of the infection and the species being treated.[5] [6]

Dosage and administration

The dosage of toltrazuril varies depending on the species and the formulation of the medication. It is available in various forms, including oral suspensions, solutions, and powders. For accurate dosing, it is crucial to follow veterinary advice or using a reliable dosage calculator. One such tool is the Toltrazuril 5% Coccishield Max Dosage Calculator.[7] [8]

Safety and side effects

Toltrazuril is generally well-tolerated by animals, with minimal side effects when used at the recommended dosages. However, some animals may experience gastrointestinal upset, including diarrhea or vomiting. It is important to use this medication under the guidance of a veterinarian to avoid potential overdosing or underdosing.[9]
