Activated Charcoal Magnesium Hydroxide
Activated Charcoal/Magnesium Hydroxide is a combination medication pairing an adsorbent agent with a saline laxative. The activated charcoal binds to ingested toxins and medications in the gastrointestinal tract to prevent their absorption, while magnesium hydroxide acts as an osmotic laxative to promote bowel movements and prevent constipation that can result from the charcoal. This combination is commonly used in the management of acute poisoning and drug overdoses.

Treatment of acute oral poisoning and drug overdoses, including overdose from medications, chemicals, and certain toxins; prevention of constipation associated with activated charcoal therapy.
Activated charcoal adsorbs (binds) toxic substances in the GI tract, preventing their absorption into the bloodstream. Magnesium hydroxide draws water into the intestines and promotes peristalsis, acting as an osmotic laxative to facilitate elimination of bound toxins.
Most effective when administered within 1-2 hours of ingestion. Contraindicated in patients with compromised airways, intestinal perforation, or those who have ingested corrosive substances or petroleum products. Should not be taken with other oral medications as it may reduce their absorption. Medical evaluation is essential after any poisoning exposure.
