Toxic megacolon as a rare complication following atropine therapy due to organophosphate poisoning: A case report

The main therapeutic basis for a case of organophosphate poisoning is a combination therapy which includes atropine as an anticholinergic drug and pralidoxime. If the poisoning is severe, a high dose of this combination of medicines may be needed, but this may cause serious side effects: paralytic ileus or even megacolon; however, these gastrointestinal events are very rare. Here, we report a case of organophosphate poisoning where atropine therapy was given and led to drug-associated toxic megacolon.
