What it is used for
- Cryptosporidia-associated diarrhea
- Equine protozoal myeloencephalitis (EPM) caused by Sarcocystis neurona
- Relapsing EPM
How it is given
Possible side effects
- Horses: Fever, anorexia, lethargy/depression, decreased gut sounds, diarrhea/enterocolitis, colic, laminitis, head/limb edema
- Horses: 'Treatment crisis' (CNS inflammation secondary to dying protozoa)
- Dogs: Excessive salivation, vomiting, diarrhea (often therapy-limiting)
- Humans: Yellow discoloration of sclera (rare, reversible)
Cautions & contraindications
- Horses less than 1 year of age
- Horses that are sick or debilitated for reasons other than EPM
- Use with extreme caution in stallions and horses predisposed to laminitis
- Animals with compromised renal or hepatic function (safety not established)
- Use with caution in animals with compromised renal or hepatic function. In horses, monitor closely for signs of enterocolitis (disruption of normal flora) and laminitis (stallions may be more prone). A 'treatment crisis' may occur in horses during the first two weeks of EPM therapy due to CNS inflammation from dying protozoa, which may require anti-inflammatory therapy. Not evaluated in horses weighing > 1200 lbs.
Drug interactions
- Highly protein-bound drugs with narrow therapeutic index: Use with caution; tizoxanide is >99% protein bound and may displace or be displaced by other highly bound drugs, potentially altering free drug concentrations.
