Vomiting caffeine

Large doses of caffeine can cause nausea and vomiting. Caffeine is a potent stimulant of hydrochloric acid secretion (20) and has been incriminated in exacerbating duodenal ulcers. However, decaffeinated coffee has also been reported to be as potent as instant coffee in stimulating gastric acid secretion (20). 

Several factors predispose to lithium toxicity, including sodium restriction, dehydration, vomiting, diarrhea, drug interactions that decrease lithium clearance, heavy exercise, sauna baths, hot weather, and fever. Patients should be told to maintain adequate sodium and fluid intake and to avoid excessive coffee, tea, cola, and other caffeine-containing beverages and alcohol. 

Physical effects of high doses of ketamine include decreased respiration and heart rate, increased blood pressure, and the possibility of vomiting and convulsions. These can lead to cardiac and respiratory arrest, coma, and death. The risk of ketamine overdose is much greater when it is mixed with other drugs such as alcohol, Ecstasy, caffeine, or cocaine. Overdoses of ketamine have been reported when people boost the drug (take another dose before the first dose wears off) to prolong its psychedelic effects. 

Headaches Arising from Contact with NG or Dynamites. Test exposure (oral and skin contact) to a 20% NG Dynamite produced severe headaches, nausea and vomiting. These effects are ascribed to intracranial vasodilation produced by the NG vapors or liquid. Headaches were alleviated by intramuscular injection of caffeine-Na-benzoate followed by oral administration of... 

A 73-year-old man with diabetic gangrene who had used insulin and acarbose 300 mg/day for 15 months developed ileus with abdominal pain and vomiting after he took PL granules (containing salicylamide, paracetamol, anhydrous caffeine, and promethazine methylene disalicylate) for a common cold (51). The ileus subsided after acarbose and the other drugs were withdrawn. 

People with anorexia nervosa starve themselves. People with bulimia eat and purge their food by vomiting or by some other means. People with both conditions may take diet pills, as well as laxatives, diuretics, and caffeine beverages. 

Caffeine qualifies as an addicting drug because it presents qualities of reinforcement and its withdrawal induces a syndrome of symptoms. These include headache, drowsiness, fatigue, decreased performance, depression, and occasionally nausea and vomiting. Symptoms appear within 12-24 hours of last caffeine use, peak at 20-48 hours, and last about 1 week. Although withdrawal symptoms are more common in moderate to heavy users of caffeine (in excess of three cups of coffee a day), it can also occur with low to moderate intake (235 mg/day, equivalent to 2.5 cups of coffee). 

Cardamom is also used internally for indigestion, nausea, vomiting and pulmonary disease with copious phlegm and also as a laxative to prevent stomach pain and griping, as well as flatulence. The seeds are also chewed to sweeten the breath and taken to detoxify caffeine in people drinking excessive amounts of coffee.

Caffeine is a stimulant of the central nervous system. It eliminates fatigue and drowsiness. However, high doses cause gastrointestinal motility, restlessness, sleeplessness, nervousness, and tremor. Acute poisoning effects include nausea, vomiting, headache, excitability, tremor, and sometimes, convulsive coma. Other symptoms may be respiratory depression, muscle contraction, distorted perception, and hallucination. Ingestion of 15-20 g may be fatal to humans. 

Similar to the clinical efficacy of theophylline, side effects are also closely related to sernm concentrations. No critical side effects have been observed at sernm theophylline levels np to 20 pg/ml. However, transient comparatively slight side effects similar to those of caffeine, including nausea, vomiting, headache, diarrhea, and insomnia, occnr in some patients at theophylline sernm concentrations below 20 pg/ml. These side effects may be present in np to 50% of patients when serum concentrations of 10 to 20 pg/ml are rapidly achieved, bnt they are usually much less frequent when the initial dose is low and the hnal drng concentration is gradually achieved by increasing doses in intervals of at least 3 days. 

A. The earliest symptoms of acute caffeine poisoning are usually anorexia, tremor, and restlessness. These are followed by nausea, vomiting, tachycardia, and confusion. With serious intoxication, delirium, seizures, supraventricular and ventricular tachyarrhythmias, hypokalemia, and hyperglycemia may occur. Hypotension is caused by excessive beta-2-mediated vasodilation and is characterized by a low diastolic pressure and a wide pulse pressure. 

IV. Diagnosis is suggested by the history of caffeine exposure or the constellation of nausea, vomiting, tremor, tachycardia, seizures, and hypokalemia (also consider theophylline see p 354).
