A.k.a activated carbon, activated charcoal is administered orally to absorb certain drugs or toxins to prevent or reduce their systemic absorption. This reduces the severity of the clinical and physiological signs associated with the poison the pet has recently ingested.

Usually given after Gastric lavage (Stomach pumping), Activated Charcoal works by absorbing chemicals, to reduce toxicity, through the entire length of the stomach and intestines and is estimated to reduce absorption of poisonous substances up to 60%.
