Altered blood bears resemblance to coffee grounds (as the iron in the blood is oxidized) and, when this matter is identified, the term coffee-ground vomiting is used. Bile can enter the vomit during subsequent heaves due to duodenal contraction if the
If dehydration is so severe as to cause shock (severely decreased blood pressure with insufficient blood supply to the body's organs), or a depressed level of consciousness, rapid infusion of saline (1 liter for adults, 10 mL/kg in repeated doses for children) is recommended to restore circulating volume.
Treatment may include activated charcoal if the person seeks medical help soon after the overdose. [1] Attempting to force the person to vomit is not recommended. [6] If there is a potential for toxicity, the antidote acetylcysteine is recommended. [1] The medication is generally given for at least 24 hours. [6]
Physostigmine, a cholinergic drug that readily crosses the blood–brain barrier, has been used as an antidote to treat the central nervous system depression symptoms of a scopolamine overdose. [33] Other than this supportive treatment, gastric lavage and induced emesis (vomiting) are usually recommended as treatments for oral overdoses. [32]
