question: Why you shouldn't vomit after accidentally ingesting chemical products?
comment: First of all, that's not an absolute, sometimes you should. Secondly, when you don't have to. What you want to avoid is the chemicals to injure you further going again thorough the trachea and throat that is much less protected than the stomach. Add to that the fact that you also throw up chloridic acid which can injure you even more
passages: The other elimination pathways are less important in the elimination of drugs, except in very specific cases, such as the respiratory tract for alcohol or anaesthetic gases. The case of mother's milk is of special importance. The liver and kidneys of newly born infants are relatively undeveloped and they are highly sensitive to a drug’s toxic effects. For this reason it is important to know if a drug is likely to be eliminated from a woman’s body if she is breast feeding in order to avoid this situation.
  
  Section::::Pharmacokinetic parameters of elimination.
   It takes around five days of total abstinence to unmask a food or chemical, during the first week on an elimination diet withdrawal symptoms can occur but it takes at least two weeks to remove residual traces. If symptoms have not subsided after six weeks, food intolerance is unlikely to be involved and a normal diet should be restarted. Withdrawals are often associated with a lowering of the threshold for sensitivity which assists in challenge testing, but in this period individuals can be ultra-sensitive even to food smells so care must be taken to avoid all exposures.
   Contrary to common misconception, swallowing gasoline does not generally require special emergency treatment, and inducing vomiting does not help, and can make it worse. According to poison specialist Brad Dahl, "even two mouthfuls wouldn't be that dangerous as long as it goes down to your stomach and stays there or keeps going." The US CDC's Agency for Toxic Substances and Disease Registry says not to induce vomiting, lavage, or administer activated charcoal.
  
  Section::::Safety.:Inhalation for intoxication.
   While on the diet some patients become sensitive to fumes and odours, which may also cause symptoms. They are advised to avoid such exposures as this can complicate the elimination and challenge procedures. Petroleum products, paints, cleaning agents, perfumes, smoke and pressure pack sprays are particular chemicals to avoid when participating in an elimination diet. Once the procedure is complete this sensitivity becomes less of a problem.
   BULLET::::- 15 – 20 minutes - moderate to severe irritants and chemicals that cause acute toxicity
  
  BULLET::::- 30 minutes - most corrosives
  
  BULLET::::- 60 minutes - strong alkalis such as sodium, potassium or calcium hydroxide
  
  Transporting the affected person to a health care facility may be important, depending on condition. In the case that the victim needs to be transported before the recommended flush time, then flushing should be done during the transportation process. Some chemical manufacturers may state the specific type of cleansing agent that is recommended.

   In addition, the National Library of Medicine Toxicology Data Network (TOXNET) reviewed the range of toxicity of CPC, and stated that, "Significant toxicity is rare after exposure to low concentration products that are typically available in the home."
  
  The fatal dose in humans ingesting cationic detergents has been estimated to be 1 to 3 g. Therefore, a person using a typical oral ingestible product that provides 0.25 mg CPC per dose will need to take 4000 doses at one time before they would be in the estimated fatal dose range.
   Inducing vomiting with syrup of ipecac has no role in paracetamol overdose because the vomiting it induces delays the effective administration of activated charcoal and oral acetylcysteine. Liver injury is extremely rare after acute accidental ingestion in children under 6 years of age. Children with accidental exposures do not require gastrointestinal decontamination with either gastric lavage, activated charcoal, or syrup of ipecac.
  
  Section::::Treatment.:Acetylcysteine.
   Defensive vomiting
  
  Defensive vomiting refers to the use of emesis to defend against ingested pathogens or, in animals, against predators.
  
  Section::::In humans.
  
  Vomiting serves an evolutionary purpose for humans by preventing the ingestion of something harmful, and by expelling noxious substances once ingested.
  
  Vomiting excessive amounts of alcohol is an attempt by the body to prevent alcohol poisoning and death. Vomiting may also be caused by other drugs, such as opiates, or toxins found in some foods and plants. Food allergies and sensitivities, such as lactose intolerance, can cause vomiting.
   Caustic ingestion
  
  Caustic ingestion occurs when someone accidentally or deliberately ingests a caustic or corrosive substance. Depending on the nature of the substance, the duration of exposure and other factors it can lead to varying degrees of damage to the oral mucosa, the esophagus, and the lining of the stomach.
  
  The severity of the injury can be determined by endoscopy of the upper digestive tract, although CT scanning may be more useful to determine whether surgery may be required.
  
  During the healing process, strictures of the oesophagus may form, which may require therapeutic dilatation and insertion of a stent.
   BULLET::::- "Aspiration hazard" includes severe acute effects such as chemical pneumonia, varying degrees of pulmonary injury or death following aspiration. Aspiration is the entry of a liquid or solid directly through the oral or nasal cavity, or indirectly from vomiting, into the trachea and lower respiratory system. Substances and mixtures of this hazard class are assigned to one of two hazard categories this hazard class on the basis of viscosity.
  
  Section::::Hazard classification.:Environmental hazards.
   BULLET::::- "Toxins" may either be present naturally in food or released by bacteria or from contamination of food products.
  
  BULLET::::- "Psychological reactions" involve manifestation of clinical symptoms caused not by the food but by emotions associated with the food. The symptoms do not occur when the food is given in an unrecognizable form. Although an individual may have an adverse reaction to a food, this is not considered a food intolerance.
  
  Elimination diets are useful to assist in the diagnosis of food allergy and pharmacological food intolerance. Metabolic, toxic and psychological reactions should be diagnosed by other means.
  
  Section::::Diagnosis.
   After two or more weeks if the symptoms have reduced considerably or gone for at least five days then challenge testing can begin. This can be carried out with selected foods containing only one food chemical, to isolate it if reactions occur. In Australia, purified food chemicals in capsule form are available to doctors for patient testing. These are often combined with placebo capsules for control purposes. This type of challenge is more definitive. New challenges should only be given after 48 hours if no reactions occur or after five days of no symptoms if reactions occur.
   Since both the digestive system and the respiratory system are connected by the pharynx, there are many problems and diseases that occur when the body is unable to regulate passage of food and air into the appropriate tracts. Perhaps the most preventable cause of damage to these reflexes originates from smoking. One study has shown that, when compared to non-smokers, the threshold volumes (in other words the lowest volume at which one of these reflexes is triggered) for both the pharyngo-upper esophageal sphincter contractile reflex and reflexive pharyngeal swallowing is increased.

  BULLET::::- Retching, also known as dry heaving
   BULLET::::- "Metabolic food reactions" are due to an inborn or acquired errors of metabolism of nutrients such as in diabetes mellitus, lactase deficiency, phenylketonuria and favism. Toxic food reactions are caused by the direct action of a food or additive without immune involvement.
  
  BULLET::::- "Pharmacological reactions" are generally to low molecular weight chemicals which occur either as natural compounds such as salicylates, amines, or to artificially added substances such as preservatives, coloring, emulsifiers and taste enhancers including glutamate (MSG). These chemicals are capable of causing drug-like (biochemical) side effects in susceptible individuals.
   Vomiting is different from regurgitation, though the terms are often used interchangeably. Regurgitation is the return of undigested food back up the esophagus to the mouth, without the force and displeasure associated with vomiting. The causes of vomiting and regurgitation are generally different.
  
  Section::::Complications.
  
  Section::::Complications.:Aspiration.
  
  Vomiting is dangerous if gastric content enters the respiratory tract. Under normal circumstances the gag reflex and coughing prevent this from occurring; however, these protective reflexes are compromised in persons under the influence of certain substances (including alcohol) or even mildly anesthetized. The individual may choke and asphyxiate or suffer aspiration pneumonia.
   DEET may be quantitated in blood, plasma or urine by gas or liquid chromatography-mass spectrometry to confirm a diagnosis of poisoning in hospitalized patients or to provide evidence in a medicolegal death investigation. Blood or plasma DEET concentrations are expected to be in a range of 0.3-3.0 mg/L during the first 8 hours after dermal application in persons using the chemical appropriately, 6 mg/L in intoxicated patients and 100 mg/L in victims of acute intentional oral overdose.
  
  Section::::Effects on materials.
   Chemicals can change their physical state depending on temperature or pressure. Thus it is important to identify the health risks as these states can determine the potential route the chemical will take. For example, gas state chemicals will be inhaled or liquid state chemicals can be absorbed by the skin.

  Section::::Symbols.
   BULLET::::- Nasogastric aspiration involves the placement of a tube via the nose down into the stomach, the stomach contents are then removed by suction. This procedure is mainly used for liquid ingestions where activated charcoal is ineffective, e.g. ethylene glycol poisoning.
   Avoidance of ethanol is the safest, surest, and cheapest treatment. Indeed, surveys find a positive correlation between high incidences of glu487lys ALDH2 allele-related alcohol-induced respiratory reactions as well as other causes of these reactions and low levels of alcohol consumption, alcoholism, and alcohol-related diseases. Evidently, people suffering these reaction self-impose avoidance behavior. There is a proviso here: ethanol, at surprisingly high concentrations, is used as a solvent to dissolve many types of medicines and other ingredients. This pertains particularly to liquid cold medicines and mouthwashes. Ethanol avoidance includes avoiding the ingestion of and, depending on an individual's history, mouth washing with, such agents.
   On other occasions drugs combine with bile juices and enter the intestines. In the intestines the drug will join with the unabsorbed fraction of the administered dose and be eliminated with the faeces or it may undergo a new process of absorption to eventually be eliminated by the kidney.
   BULLET::::- Mucin: The stomach has a priority to destroy the bacteria and viruses using its highly acidic environment but also has a duty to protect its own lining from its acid. The way that the stomach achieves this is by secreting mucin and bicarbonate via its mucous cells, and also by having a rapid cell turn-over.
   BULLET::::- In severe cases, patient can suffer apnea secondary to motor block, requiring mechanical ventilation.
  
  Usually, the victims of mild and severe acute intoxications eliminate the toxin in urine during the first 24 hours after ingestion, and improve to full recovery in the first day of intrahospital care (when vital support is provided in a timely manner).
   Over a period of time it is possible for individuals avoiding food chemicals to build up a level of resistance by regular exposure to small amounts in a controlled way, but care must be taken, the aim being to build up a varied diet with adequate composition.
  
  Section::::Prognosis.
   BULLET::::- Treatment of a recently ingested poison may involve gastric decontamination to decrease absorption. Gastric decontamination can involve activated charcoal, gastric lavage, whole bowel irrigation, or nasogastric aspiration. Routine use of emetics (syrup of Ipecac), cathartics or laxatives are no longer recommended.
