Should activated charcoal be used with lithium?

Activated charcoal should not be used with lithium due to the potential for complications. Lithium is a medication that has a narrow therapeutic index, meaning that there is a small margin between therapeutic and toxic doses. The primary concern with using activated charcoal in cases of lithium ingestion is that it can interfere with the absorption and elimination of lithium, potentially leading to increased plasma levels and a higher risk of toxicity.

Lithium is primarily eliminated through the kidneys, and activated charcoal may not effectively reduce lithium levels if significant time has passed since ingestion. In addition, complications can arise such as gastrointestinal obstruction or aspiration if the charcoal is administered inappropriately. Thus, clinical guidelines typically recommend avoiding activated charcoal in cases of lithium ingestion due to these risks.

In circumstances where lithium overdose is suspected, more careful approaches and monitoring need to be employed, potentially involving hemodialysis if the serum lithium levels are significantly elevated, rather than relying on activated charcoal as an intervention.
