There is no evidence that any treatment for hangovers is very effective.
- Rehydration: Drinking water before going to bed or during hangover may relieve dehydration-associated symptoms such as thirst, dizziness, dry mouth, and headache.
- Non-steroidal anti-inflammatory drugs such as aspirin or ibuprofen have been proposed as a treatment for the headaches associated with a hangover. There however is no evidence to support a benefit, and there are concerns that taking alcohol and aspirin together may increase the risk of stomach bleeding and liver damage.
- Tolfenamic acid, an inhibitor of prostaglandin synthesis, in a 1983 study reduced headache, nausea, vomiting, irritation but had no effect on tiredness in 30 people.
- Pyritinol: A 1973 study found that large doses (several hundred times the recommended daily intake) of Pyritinol, a synthetic Vitamin B6 analog, can help to reduce hangover symptoms. Possible side effects of pyritinol include hepatitis (liver damage) due to cholestasis and acute pancreatitis.
- Yeast-based extracts: The difference in the change for discomfort, restlessness, and impatience were statistically significant but no significant differences on blood chemistry parameters, blood alcohol or acetaldehyde concentrations have been found, and it did not significantly improve general well-being.
Recommendations for foods, drinks and activities to relieve hangover symptoms abound. The ancient Romans, on the authority of Pliny the Elder, favored raw owl's eggs or fried canary, while the "prairie oyster" restorative, introduced at the 1878 Paris World Exposition, calls for raw egg yolk mixed with Worcestershire sauce, Tabasco sauce, salt and pepper. By 1938, the Ritz-Carlton Hotel provided a hangover remedy in the form of a mixture of Coca-Cola and milk (Coca-Cola itself having been invented, by some accounts, as a hangover remedy). Alcoholic writer Ernest Hemingway relied on tomato juice and beer. Other purported hangover cures include cocktails such as Bloody Mary or Black Velvet (consisting of equal parts champagne and stout). A 1957 survey by an American folklorist found widespread belief in the efficacy of heavy fried foods, tomato juice and sexual activity.
Other untested or discredited treatments include:
- Hair of the dog: The belief is that consumption of further alcohol after the onset of a hangover will relieve symptoms, based upon the theory that the hangover represents a form of alcohol withdrawal and that by satiating the body's need for alcohol the symptoms will be relieved. Social drinkers and alcoholics claim that drinking more alcohol gives relief from hangover symptoms, but research shows that the use of alcohol as a hangover cure seems to predict current or future problem drinking and alcohol use disorder, through negative reinforcement and the development of physical dependence. While the practice is popular in tradition and promoted by many sellers of alcoholic beverages, medical opinion holds that the practice merely postpones the symptoms, and courts addiction. Favored choices include Fernet Branca and Bloody Mary.
- Kudzu ("Pueraria montana var. lobata"): The main ingredient in remedies such as kakkonto. A study concluded, "The chronic usage of "Pueraria lobata" at times of high ethanol consumption, such as in hangover remedies, may predispose subjects to an increased risk of acetaldehyde-related neoplasm and pathology. ... Pueraria lobata appears to be an inappropriate herb for use in herbal hangover remedies as it is an inhibitor of ALDH2."
- Artichoke: Research shows that artichoke extract does not prevent the signs and symptoms of alcohol-induced hangover.
- Sauna or steam-bath: Medical opinion holds this may be dangerous, as the combination of alcohol and hyperthermia increases the likelihood of dangerous cardiac arrhythmias.
- Oxygen: There have been anecdotal reports from those with easy access to a breathing oxygen supply – medical staff, and military pilots — that oxygen can also reduce the symptoms of hangovers sometimes caused by alcohol consumption. The theory is that the increased oxygen flow resulting from oxygen therapy improves the metabolic rate, and thus increases the speed at which toxins are broken down. However, one source states that (in an aviation context) oxygen has no effect on physical impairment caused by hangover.
- Fructose and glucose: Glucose and fructose significantly inhibit the metabolic changes produced by alcohol intoxication, nevertheless they have no significant effect on hangover severity.
- Vitamin B: No effects on alcohol metabolism, peak blood alcohol and glucose concentrations have been found and psychomotor function is not significantly improved when using Vitamin B supplements.
- Caffeinated drinks: No significant correlation between caffeine use and hangover severity has been found.
Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression and/or inhalation of vomit if emesis occurs while the patient is unconscious and unresponsive. Emergency treatment for acute alcohol poisoning strives to stabilize the patient and maintain a patent airway and respiration, while waiting for the alcohol to metabolize. This can be done by removal of any vomitus or, if patient is unconscious or has impaired gag reflex, intubation of the trachea using an endotracheal tube to maintain adequate airway:
Also:
- Treat hypoglycaemia (low blood sugar) with 50 ml of 50% dextrose solution and saline flush, as ethanol induced hypoglycaemia is unresponsive to glucagon.
- Administer the vitamin thiamine to prevent Wernicke-Korsakoff syndrome, which can cause a seizure (more usually a treatment for chronic alcoholism, but in the acute context usually co-administered to ensure maximal benefit).
- Apply hemodialysis if the blood concentration is dangerously high (>400 mg/dL), and especially if there is metabolic acidosis.
- Provide oxygen therapy as needed via nasal cannula or non-rebreather mask.
- Provide parenteral Metadoxine.
Additional medication may be indicated for treatment of nausea, tremor, and anxiety.
Over the counter medications are those medications that do not require a prescription to purchase in the US. Medications that require a prescription to purchase in the US may be available in other countries without a prescription. The following guidelines are recommended:
- taking oral medications after breastfeeding rather than before will allow some of the medication to leave the mother's body through her kidneys between nursings.
- in most women without kidney disease, nonsteroidal anti-inflammatory drugs and paracetamol (acetaminophen) are used safely.
- aspirin can cause rashes and even cause bleeding in infants.
- limit the use of antihistamines for long periods of time. These anti-allergy medications can cause crying, sleep problems, fussiness, exsessive sleepiness in babies. Antihistamines have an effect on the amount of milk the body produces and decrease the supply.
- carefully observe the infant for changes or side effects when first taking a medication to watch for side effects. Side effects indicating that the medication is having an affect on the baby is difficulty breathing, rash and other questionable changes that occurred after the medication was started by the mother.
- many times other young children are in the home and keeping these over the counter medications out of their reach is a safe practice.
Other substances or chemicals have been evaluated regarding their safe use during pregnancy. Hair dye or solutions used for a 'permanent' do not pass to breastmilk. No adverse reports of using oral antihastamines and breastfeeding are found. Some of the older antihistamines used by a nursing mother can cause drowsiness in the infant. This may be a concern if the infant misses feedings by sleeping instead of nursing.
RWH could be caused by the release of prostaglandins which some people are not able to metabolize. Prostaglandins are substances that can contribute to pain and swelling. Ibuprofen (Advil), paracetamol (Tylenol) and aspirin are prostaglandin inhibitors. Aspirin and ibuprofen were shown to be effective at blocking both early and late stages of the RWH, and paracetamol (acetaminophen) was effective in blocking the early stage. However, combining paracetamol/acetaminophen and/or NSAIDs (like ibuprofen) with alcohol are not good for the liver, and can be potentially harmful. Some individuals will experience extreme nausea, vomiting, and abdominal pain when combining alcohol with acetaminophen and/or NSAIDs. The combination should never be used.
Alcoholics may also require treatment for other psychotropic drug addictions and drug dependences. The most common dual dependence syndrome with alcohol dependence is benzodiazepine dependence, with studies showing 10–20 percent of alcohol-dependent individuals had problems of dependence and/or misuse problems of benzodiazepine drugs such as valium or clonazopam. These drugs are, like alcohol, depressants. Benzodiazepines may be used legally, if they are prescribed by doctors for anxiety problems or other mood disorders, or they may be purchased as illegal drugs "on the street" through illicit channels. Benzodiazepine use increases cravings for alcohol and the volume of alcohol consumed by problem drinkers. Benzodiazepine dependency requires careful reduction in dosage to avoid benzodiazepine withdrawal syndrome and other health consequences. Dependence on other sedative-hypnotics such as zolpidem and zopiclone as well as opiates and illegal drugs is common in alcoholics. Alcohol itself is a sedative-hypnotic and is cross-tolerant with other sedative-hypnotics such as barbiturates, benzodiazepines and nonbenzodiazepines. Dependence upon and withdrawal from sedative-hypnotics can be medically severe and, as with alcohol withdrawal, there is a risk of psychosis or seizures if not managed properly.
In the United States there are four approved medications for alcoholism: disulfiram, two forms of naltrexone, and acamprosate. Several other drugs are also used and many are under investigation.
- Benzodiazepines, while useful in the management of acute alcohol withdrawal, if used long-term can cause a worse outcome in alcoholism. Alcoholics on chronic benzodiazepines have a lower rate of achieving abstinence from alcohol than those not taking benzodiazepines. This class of drugs is commonly prescribed to alcoholics for insomnia or anxiety management. Initiating prescriptions of benzodiazepines or sedative-hypnotics in individuals in recovery has a high rate of relapse with one author reporting more than a quarter of people relapsed after being prescribed sedative-hypnotics. Those who are long-term users of benzodiazepines should not be withdrawn rapidly, as severe anxiety and panic may develop, which are known risk factors for relapse into alcohol abuse. Taper regimes of 6–12 months have been found to be the most successful, with reduced intensity of withdrawal.
- Acamprosate may stabilise the brain chemistry that is altered due to alcohol dependence via antagonising the actions of glutamate, a neurotransmitter which is hyperactive in the post-withdrawal phase. By reducing excessive NMDA activity which occurs at the onset of alcohol withdrawal, acamprosate can reduce or prevent alcohol withdrawal related neurotoxicity. Acamprosate reduces the risk of relapse amongst alcohol dependent persons.
- Disulfiram (Antabuse) prevents the elimination of acetaldehyde, a chemical the body produces when breaking down ethanol. Acetaldehyde itself is the cause of many hangover symptoms from alcohol use. The overall effect is severe discomfort when alcohol is ingested: an extremely fast-acting and long-lasting uncomfortable hangover. This discourages an alcoholic from drinking in significant amounts while they take the medicine.
- Naltrexone is a competitive antagonist for opioid receptors, effectively blocking the effects of endorphins and opioids. Naltrexone is used to decrease cravings for alcohol and encourage abstinence. Alcohol causes the body to release endorphins, which in turn release dopamine and activate the reward pathways; hence when naltrexone is in the body there is a reduction in the pleasurable effects from consuming alcohol. Evidence supports a reduced risk of relapse among alcohol dependent persons and a decrease in excessive drinking. Nalmefene also appears effective and works by a similar manner.
- Calcium carbimide works in the same way as disulfiram; it has an advantage in that the occasional adverse effects of disulfiram, hepatotoxicity and drowsiness, do not occur with calcium carbimide.
The Sinclair method is a method of using naltrexone or another opioid antagonists to treat alcoholism by having the person take the medication about an hour before they drink alcohol, and only then. The medication blocks the positive reinforcement effects of ethanol and hopefully allows the person to stop drinking or drink less.
Evidence does not support the use of selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), antipsychotics, or gabapentin.
A normal liver detoxifies the blood of alcohol over a period of time that depends on the initial level and the patient's overall physical condition. An abnormal liver will take longer but still succeeds, provided the alcohol does not cause liver failure.
People having drunk heavily for several days or weeks may have withdrawal symptoms after the acute intoxication has subsided.
A person consuming a dangerous amount of alcohol persistently can develop memory blackouts and idiosyncratic intoxication or pathological drunkenness symptoms.
Long-term persistent consumption of excessive amounts of alcohol can cause liver damage and have other deleterious health effects.
The anti-bacterial nature of alcohol has long been associated with soothing stomach irritations and ailments like traveler's diarrhea where it was a preferred treatment to the less palatable bismuth treatments. The risk of infection from the bacterium "Helicobacter pylori", strongly associated with causing gastritis and peptic ulcers as well as being closely linked to stomach cancer, appears to lessen with moderate alcohol consumption. A German study conducted in the late 1990s showed that non-drinkers had slightly higher infection rates of "Helicobacter pylori" than moderate wine and beer drinkers.
Wine's positive effects on the metabolism of cholesterol has been suggested as a link to lower occurrences of gallstones among moderate drinkers since cholesterol is a major component of gallstones.
One of the short-term effects of alcohol is impaired mental function, which can cause behavioral changes and memory impairment. Long-term effects of heavy drinking can inhibit new brain cell development and increase the risk for developing major depressive disorders. Studies have linked moderate alcohol consumption to lower risk of developing Alzheimer's and dementia though wine's role in this link is not yet fully understood. A 2009 study by Wake Forest University School of Medicine suggest that moderate alcohol consumption may help healthy adults ward off the risks of developing dementia but can accelerate declining memory for those already suffering from cognitive impairment. The reason for the potential positive benefit of moderate consumption is not yet identified and may even be unrelated to the alcohol but rather other shared lifestyle factors of moderate drinkers (such as exercise or diets). If it is the moderate consumption, researchers theorize that it may be alcohol's role in promoting the production of "good cholesterol" which prevents blood platelets from sticking together. Another potential role of alcohol in the body may be in stimulating the release of the chemical acetylcholine which influences brain function and memory.
Tyramine may well be a major player in RWH syndrome. Tyramine is an amine that is produced naturally from the breakdown of protein as food ages. More specifically it is formed by the decarboxylation of the amino acid tyrosine. It is found in aged, fermented, and spoiled foods. Everyday foods we consume including aged cheeses, overripe and dried fruit, sauerkraut, soy, and many processed foods contain high levels of tyramine. Tyramine is suspected of inducing migraine headaches in about 40% of migraine sufferers, according to F.G.Freitag of Diamond Headache Clinic in Chicago.
A related issue is overprescription, which occurs when doctors give prescription drugs to patients who do not need them. Antibiotics are a common example, as are narcotic painkillers. Aggressive marketing by drug companies is sometimes cited as a reason for overprescription.
A number of medications have been approved for the treatment of substance abuse. These include replacement therapies such as buprenorphine and methadone as well as antagonist medications like disulfiram and naltrexone in either short acting, or the newer long acting form. Several other medications, often ones originally used in other contexts, have also been shown to be effective including bupropion and modafinil. Methadone and buprenorphine are sometimes used to treat opiate addiction. These drugs are used as substitutes for other opioids and still cause withdrawal symptoms.
Antipsychotic medications have not been found to be useful. Acamprostate is a glutamatergic NMDA antagonist, which helps with alcohol withdrawal symptoms because alcohol withdrawal is associated with a hyperglutamatergic system.
Psychedelics, such as LSD and psilocin, may have anti-addictive properties.
Sobriety is the condition of not having any measurable levels, or effects from mood-altering drugs. According to WHO "Lexicon of alcohol and drug terms..." sobriety is continued abstinence from psychoactive drug use. Sobriety is also considered to be the natural state of a human being given at a birth. In a treatment setting, sobriety is the achieved goal of independence from consuming or craving mind-altering substances. As such, sustained abstinence is a prerequisite for sobriety. Early in abstinence, residual effects of mind-altering substances can preclude sobriety. These effects are labeled "PAWS", or "post acute withdrawal syndrome". Someone who abstains, but has a latent desire to resume use, is not considered truly sober. An abstainer may be subconsciously motivated to resume drug use, but for a variety of reasons, abstains (e.g. such as a medical or legal concern precluding use). Sobriety has more specific meanings within specific contexts, such as the culture of Alcoholics Anonymous, other 12 step programs, law enforcement, and some schools of psychology. In some cases, sobriety implies achieving "life balance".
From the applied behavior analysis literature, behavioral psychology, and from randomized clinical trials, several evidenced based interventions have emerged: behavioral marital therapy, motivational Interviewing, community reinforcement approach, exposure therapy, contingency management They help suppress cravings and mental anxiety, improve focus on treatment and new learning behavioral skills, ease withdrawal symptoms and reduce the chances of relapse.
In children and adolescents, cognitive behavioral therapy (CBT) and family therapy currently has the most research evidence for the treatment of substance abuse problems. Well-established studies also include ecological family-based treatment and group CBT. These treatments can be administered in a variety of different formats, each of which has varying levels of research support Research has shown that what makes group CBT most effective is that it promotes the development of social skills, developmentally appropriate emotional regulatory skills and other interpersonal skills. A few integrated treatment models, which combines parts from various types of treatment, have also been seen as both well-established or probably effective. A study on maternal alcohol and drug use has shown that integrated treatment programs have produced significant results, resulting in higher negative results on toxicology screens. Additionally, brief school-based interventions have been found to be effective in reducing adolescent alcohol and cannabis use and abuse. Motivational interviewing can also be effective in treating substance use disorder in adolescents.
Alcoholics Anonymous and Narcotics Anonymous are one of the most widely known self-help organizations in which members support each other not to use alcohol. Social skills are significantly impaired in people suffering from alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. It has been suggested that social skills training adjunctive to inpatient treatment of alcohol dependence is probably efficacious, including managing the social environment.
Meth mouth is very difficult to treat unless the patient stops using methamphetamine; persistent drug use makes changes in hygiene or nutrition practices unlikely. Many drug users lack access to dental treatment, and few are willing to participate in such a course of action, often because of poverty. Those who are willing to seek dental treatment often resist discussing their drug use. Providing dental treatment to individuals who use methamphetamine can also be dangerous, because the potential combination of local anesthetic and methamphetamine can cause serious heart problems. There is also an increased risk of serious side effects if opioid medications are used in the patient's treatment.
Treatment of meth mouth usually attempts to increase salivary flow, halt tooth decay, and encourage behavioral changes. Toothpaste with fluoride is very important to the restoration of dental health. Only prescription fluoride rinses can adequately treat the condition. Sialogogues, drugs that increase the amount of saliva in the mouth, can be used to treat dry mouth and protect against dental health problems. Pilocarpine and cevimeline are sialogogues approved by the Food and Drug Administration (FDA) to treat low salivation caused by Sjogren's syndrome and may have the potential to effectively treat dry mouth caused by methamphetamine use.
Education about oral hygiene for long-term methamphetamine users is sometimes required. Changes in diet are often necessary for recovering drug users that are receiving dental treatment, and the use of sugar-free gum may be beneficial. The consumption of water and the avoidance of beverages with a diuretic (dehydrating) effect can also help patients with meth mouth.
The determination of the safety of a medication can be evaluated by considering the following:
- The age and maturity of the infant. Full term infants are better able to metabolize medications than premature infants
- The weight of the infant.
- The amount and percentage of breastmilk consumed by the infant. An infant taking solid foods with breastfeeding will receive a lower dose of medication.
- The general health of the infant and the general health of the mother.
- The nature of the mother's illness, if present.
- The general information about the drug other literature documenting studies related to the drug and breastfeeding.
- The duration of the drug therapy.
- Is the drug short-acting? A short-acting form of the drug may be a better choice for a breastfeeding mother rather than a longer-acting form that stays in the mother's system for a longer period.
- How is the medication being given?
- Does the drug interfere with lactation?
The overmedication of children has dramatically risen with those between the ages of 2 and 5 years old who are being prescribed atypical antipsychotics for bipolar disorders, developmental disabilities, ADHD, and behavior disorders. Drug companies have benefited considerably with profits made in sales for drugs such as stimulants for hyperactive children, with half a million children in the United States receiving medication. Children have become more involved with technology resulting in less play time outside and less time spent with parents. The long hours children spend with technology has impacted their attachment development, sensory and motor development, along with socialization skills, in return causing behavioral and psychological disorders and learning disabilities being diagnosed by psychotropic medication.
According to recent data from IMS health one of the leading services for data distribution in health care, 274,000 infants (0 to 1) are on anti-anxiety drugs, and 26,000 under a year old are on antidepressants. This is only a fraction of the millions of children 5 to 12 being prescribed these same drugs.
While these drugs can provide relief from some symptoms the children may suffer, psychiatric drugs have been shown in some instances to worsen the symptoms of mental illness and can cause adverse physical effects such as liver damage, weight gain, decreased cognitive function and dependency on the drug. (1) Antidepressants have side effects that can include suicidal thoughts and worsening depression. These medications can have long lasting effects on the children and these risks need to be taken into consideration.
It's important for parents to monitor their child's behavior and regulate their environment in order to help prevent any future affective disorders. Medication is often prescribed to these children however, it alone will not teach a child to create more valuable relationships at home or in the community. Other forms of intervention can be applied to supplement the effects of medication therapy and teach the child self-regulatory behaviors and healthy coping skills. The increase of psychiatric medication of children may be a result of the declining support for caregiving, leading to psychopathology in which drugs are oftentimes the go to method of treatment. Families do not always have knowledge regarding or the means to pursue other methods of intervention such as one-on-one therapy with the child, family therapy and parenting counseling that can teach effective parenting strategies to meet their child's specific needs. There is debate that healthcare professionals have been put under pressure to perform proficiently causing the influence of piecemeal polypharmacy.
Different countries recommend different maximum quantities. For most countries, the maximum quantity for men is 140 g–210 g per week. For women, the range is 84 g–140 g per week. Most countries recommend total abstinence during pregnancy and lactation.
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.
Type H1 antagonists in the histamine antagonist family of drugs were tested in Japanese volunteers with alcohol-induced asthma (who presumably have glu487lys ALDH2 allele-associated asthma) and found to be completely effective in blocking bronchoconstriction responses to alcoholic beverages; these blockers, it is suggested, may be taken 1–2 hours before consumption of alcohol beverages as a preventative of alcohol-induced respiratory reactions. In the absence of specific studies on the prevention of classical alcohol induced rhinitis and asthma due to allergens in alcoholic beverages, see asthma section on Prevention and rhinitis section on Prevention of allergen-induced reactions.
In the absence of specific studies on the treatment of acute alcohol-induced bronchoconstriction and rhinitis, treatment guidelines should probably follow those of their comparable allergen-induced classical allergic reactions (see asthma section on Treatment and rhinitis section on Treatment) but possibly favoring the testing of H1 antagonist anti-histamines as part of the initial protocol.
Injury is defined as damage or harm that is done or sustained. The potential of injuring oneself or others can be increased after consuming alcohol due to the certain short term effects related to the substance such as lack of coordination, blurred vision, and slower reflexes to name a few. Due to these effects the most common injuries include head, fall, and vehicle related injuries. These include a range of soft tissue damage and fractures. A study was conducted between November 1, 2001 and June 30, 2002 of patients admitted to The Ulster Hospital in Northern Ireland with fall related injuries. They found that 113 of those patients admitted to that hospital during that had consumed alcohol recently and that the injury severity was higher for those that had consumed alcohol compared to those that hadn't. Another study showed that 21% of patients admitted to the Emergency Department of the Bristol Royal Infirmary had either direct or indirect alcohol related injuries. If these figures are extrapolated it shows that the estimated number of patients with alcohol related injuries are over 7000 during the year at this ED alone.
In the United States alcohol resulted in about 88,000 deaths in 2010.
In cases of suspected copper poisoning, penicillamine is the drug of choice, and dimercaprol, a heavy metal chelating agent, is often administered. Vinegar is not recommended to be given, as it assists in solubilizing insoluble copper salts. The inflammatory symptoms are to be treated on general principles, as are the nervous ones.
There is some evidence that alpha-lipoic acid (ALA) may work as a milder chelator of tissue-bound copper. Alpha lipoic acid is also being researched for chelating other heavy metals, such as mercury.
The mainstays of treatment are removal from the source of lead and, for people who have significantly high blood lead levels or who have symptoms of poisoning, chelation therapy. Treatment of iron, calcium, and zinc deficiencies, which are associated with increased lead absorption, is another part of treatment for lead poisoning. When lead-containing materials are present in the gastrointestinal tract (as evidenced by abdominal X-rays), whole bowel irrigation, cathartics, endoscopy, or even surgical removal may be used to eliminate it from the gut and prevent further exposure. Lead-containing bullets and shrapnel may also present a threat of further exposure and may need to be surgically removed if they are in or near fluid-filled or synovial spaces. If lead encephalopathy is present, anticonvulsants may be given to control seizures, and treatments to control swelling of the brain include corticosteroids and mannitol. Treatment of organic lead poisoning involves removing the lead compound from the skin, preventing further exposure, treating seizures, and possibly chelation therapy for people with high blood lead concentrations.
A chelating agent is a molecule with at least two negatively charged groups that allow it to form complexes with metal ions with multiple positive charges, such as lead. The chelate that is thus formed is nontoxic and can be excreted in the urine, initially at up to 50 times the normal rate. The chelating agents used for treatment of lead poisoning are edetate disodium calcium (CaNaEDTA), dimercaprol (BAL), which are injected, and succimer and d-penicillamine, which are administered orally.
Chelation therapy is used in cases of acute lead poisoning, severe poisoning, and encephalopathy, and is considered for people with blood lead levels above 25 µg/dL. While the use of chelation for people with symptoms of lead poisoning is widely supported, use in asymptomatic people with high blood lead levels is more controversial. Chelation therapy is of limited value for cases of chronic exposure to low levels of lead. Chelation therapy is usually stopped when symptoms resolve or when blood lead levels return to premorbid levels. When lead exposure has taken place over a long period, blood lead levels may rise after chelation is stopped because lead is leached into blood from stores in the bone; thus repeated treatments are often necessary.
People receiving dimercaprol need to be assessed for peanut allergies since the commercial formulation contains peanut oil. Calcium EDTA is also effective if administered four hours after the administration of dimercaprol. Administering dimercaprol, DMSA (Succimer), or DMPS prior to calcium EDTA is necessary to prevent the redistribution of lead into the central nervous system. Dimercaprol used alone may also redistribute lead to the brain and testes. An adverse side effect of calcium EDTA is renal toxicity. Succimer (DMSA) is the preferred agent in mild to moderate lead poisoning cases. This may be the case in instances where children have a blood lead level >25μg/dL. The most reported adverse side effect for succimer is gastrointestinal disturbances. It is also important to note that chelation therapy only lowers blood lead levels and may not prevent the lead-induced cognitive problems associated with lower lead levels in tissue. This may be because of the inability of these agents to remove sufficient amounts of lead from tissue or inability to reverse preexisting damage.
Chelating agents can have adverse effects; for example, chelation therapy can lower the body's levels of necessary nutrients like zinc. Chelating agents taken orally can increase the body's absorption of lead through the intestine.
Chelation challenge, also known as provocation testing, is used to indicate an elevated and mobilizable body burden of heavy metals including lead. This testing involves collecting urine before and after administering a one-off dose of chelating agent to mobilize heavy metals into the urine. Then urine is analyzed by a laboratory for levels of heavy metals; from this analysis overall body burden is inferred. Chelation challenge mainly measures the burden of lead in soft tissues, though whether it accurately reflects long-term exposure or the amount of lead stored in bone remains controversial. Although the technique has been used to determine whether chelation therapy is indicated and to diagnose heavy metal exposure, some evidence does not support these uses as blood levels after chelation are not comparable to the reference range typically used to diagnose heavy metal poisoning. The single chelation dose could also redistribute the heavy metals to more sensitive areas such as central nervous system tissue.
The European Food Safety Authority concluded that chromium is not an essential nutrient, making this the only mineral for which the United States and the European Union disagree. The proposed mechanism for cellular uptake of Cr via transferrin has been called into question. There is no proof that chromium supplementation has physiological effects on body mass or composition, and its use as a supplement may be unsafe. A 2014 systematic review concluded that chromium supplementation had no effect on glycemic control, fasting plasma glucose levels, or body weight in people with or without diabetes.
Chromium may be needed as an ingredient in total parenteral nutrition (TPN), since deficiency may occur after months of intravenous feeding with chromium-free TPN. For this reason, chromium is added to normal TPN solutions for people with diabetes, and in nutritional products for preterm infants.
Education and counselling by physicians of children and adolescents has been found to be effective in decreasing the risk of tobacco use.
