General Drug Information and Indications

Oral di-tri-octahedral smectite adsorbent for treatment of diarrhea in horses and foals; binds bacterial toxins (C. difficile, Salmonella) to reduce intestinal inflammation. Di-tri-octahedral (DTO) smectite adsorbent. Mechanism: high surface area clay mineral with strong adsorptive capacity for bacterial toxins (Clostridioides difficile toxins A and B, Salmonella toxins, endotoxins). Coats intestinal mucosa providing a physical barrier. Not systemically absorbed. Negatively charged surface binds positively charged toxin molecules. Key information Not a drug — smectite clay adsorbent. No specific drug interactions. Safe to administer with other medications at separate times (adsorbs other drugs if given simultaneously — separate by 2 hours). Refrigerate paste form.

How to Give this Medication

Oral: dissolve in water or mix into wet feed. Administer via oral syringe or mixed into palatable liquid. May be given via nasogastric tube in foals. Separate other oral medications by 2 hrs. If a dose is missed Give the missed dose as soon as you remember. If you forget a day, simply resume the normal schedule the next day. Missing an occasional dose of this supplement is unlikely to cause harm.

Precautions

For animals Administer other oral medications separately (2 hrs before or after) — may adsorb co-administered drugs. Safe for foals and adult horses. For people handling this medication Wash hands thoroughly with soap and water after handling. Avoid contact with eyes; if contact occurs, flush with water for 15 minutes and seek medical attention.
