Fomepizole should be administered immediately to prevent further conversion of glycolic acid in the system, which contributes to profound metabolic acidosis and further life-threatening com-plications.
Physostigmine is indicated for toxicity associated with anticholinergic agents.
Although calcium and sodium bicarbonate may also be given, they would be administered when hypocalcemia and metabolic acidosis, respectively, occur. The immediate goal is to stop the conversion of glycolic acid.
