Based on a literature search performed at the bedside, it was noted that diazepam in large doses was recommended in treating chloroquine poisoning.
Chloroquine poisoning is a significantly more common problem than hydroxychloroquine poisoning, some of which may relate to chloroquine's widespread use for malaria and its use as a perceived abortifacient in Asia, Africa and the Pacific Islands (4).
Commonly recommended therapies are the same as those used for chloroquine poisoning and include inotropes, sodium bicarbonate, potassium and diazepamb (6).
Initial studies in chloroquine poisoning suggested a role for large doses of diazepam in acute poisoning, although this was not shown to be effective in a subsequent prospective controlled trial (8).
