What is the standard dosage of activated charcoal for an adult?

The standard dosage of activated charcoal for an adult typically ranges from 25 to 50 grams. This dosage is considered effective for the binding of various types of toxins and drugs in cases of oral poisoning or overdose. Activated charcoal works by adsorbing the substances in the gastrointestinal tract, preventing their absorption into the bloodstream, which is why it is a crucial treatment in emergency situations involving certain types of poisoning.

Dosages outside of this range, such as those listed in other choices, may not provide the desired effect or could be inadequate for effective treatment. For example, lower dosages like 10-20 grams are usually not sufficient for adults when significant toxic exposure is suspected, while excessively high dosages, such as 100 grams, are not typically recommended as they may lead to complications such as aspiration or gastrointestinal obstruction. The 5-10 gram range is generally considered too low to be effective in most cases of poisoning as well. Therefore, the 25-50 gram range is the standard dosage recommended for adults in emergency settings.
