Acepromazine should not be used in conjunction with certain toxicities, or in pets with heart disease or low blood pressure. It should be used cautiously in pets with mild liver or heart disease, clotting problems, or in pregnant, debilitated, or young animals. If a negative reaction occurs, call your veterinary office.

Do not use this medication in pets with liver or kidney disease, or low sodium or potassium blood levels. Use with caution in pets with acidosis, diabetes, pregnancy or lactation. If a negative reaction occurs, please call your veterinary office.

  • The combination of activated charcoal, kaolin, and sorbitol (ToxiBan® suspension with sorbitol) is a non-drug health product used to help manage poison ingestion in dogs and cats. Charcoal and kaolin bind poisons in the stomach and intestinal tract, preventing the body from absorbing them. Sorbitol accelerates defecation, and so gets the poison out of the body faster.

If a negative reaction occurs, call your veterinary office.
