When treating a patient with activated charcoal, which dosage is appropriate for adults?

  1. 10-15 gm

  2. 25-50 gm

  3. 100 gm

  4. 5-10 gm

The correct answer is: 25-50 gm

The appropriate dosage of activated charcoal for adults is in the range of 25 to 50 grams. This dosage is effective for adsorbing certain toxins and preventing their absorption in the gastrointestinal tract. Activated charcoal works by binding to various substances in the stomach and intestines, thereby reducing their availability for absorption into the body. Administering less than the recommended range, such as 10-15 grams or 5-10 grams, may not provide sufficient coverage for effective treatment of poisoning or overdose situations. Similarly, while 100 grams may seem effective, such a high dosage could lead to complications, like gastrointestinal obstruction or adverse effects without added benefit. Therefore, the 25 to 50 grams dosage is optimal for adult patients, balancing efficacy and safety.
