Norit is a product made of activated charcoal, which, due to its large internal surface, can adsorb harmful or undesirable substances in the gastrointestinal tract. Norit Carbomix is used as an emergency treatment for acute oral poisoning or drug overdose. It works by absorbing toxic substances or drugs taken in overdose in order to reduce their absorption or increase their elimination from the blood. Carbomix itself is not absorbed into the blood and passes through the gastro-intestinal tract unchanged. Carbomix is usually taken under medical supervision.
