Added flavoring
[edit]
Masking undesired taste may impair judgement of the potency, which is a factor in overdosing. For example, lean is usually created as a drinkable mixture, the cough syrup is combined with soft drinks, especially fruit-flavored drinks such as Sprite, Mountain Dew or Fanta, and is typically served in a foam cup.[9][10] A hard candy, usually a Jolly Rancher, may be added to give the mixture a sweeter flavor.[11]
Diagnosis
[edit]
The substance that has been taken may often be determined by asking the person. However, if they will not, or cannot, due to an altered level of consciousness, provide this information, a search of the home or questioning of friends and family may be helpful.
Examination for toxidromes, drug testing, or laboratory test may be helpful. Other laboratory test such as glucose, urea and electrolytes, paracetamol levels and salicylate levels are typically done. Negative drug-drug interactions have sometimes been misdiagnosed as an acute drug overdose, occasionally leading to the assumption of suicide.[12]
Prevention
[edit]
The distribution of naloxone to injection drug users and other opioid drug users decreases the risk of death from overdose.[13] The Centers for Disease Control and Prevention (CDC) estimates that U.S. programs for drug users and their caregivers prescribing take-home doses of naloxone and training on its utilization are estimated to have prevented 10,000 opioid overdose deaths.[14] Healthcare institution-based naloxone prescription programs have also helped reduce rates of opioid overdose in the U.S. state of North Carolina, and have been replicated in the U.S. military.[15][16] Nevertheless, scale-up of healthcare-based opioid overdose interventions is limited by providers' insufficient knowledge and negative attitudes towards prescribing take-home naloxone to prevent opioid overdose.[17] Programs training police and fire personnel in opioid overdose response using naloxone have also shown promise in the U.S.[18]
Supervised injection sites (also known as overdose prevention centers) have been used to help prevent drug overdoses by offering opioid reversal medications such as naloxone, medical assistance and treatment options. They also provide clean needles to help prevent the spread of diseases like HIV/AIDS and hepatitis.[19][20][21][22]
Management
[edit]
Activated carbon is a commonly used agent for decontamination of the gastrointestinal tract in overdoses.
Stabilization of the person's airway, breathing, and circulation (ABCs) is the initial treatment of an overdose. Ventilation is considered when there is a low respiratory rate or when blood gases show the person to be hypoxic. Monitoring of the patient should continue before and throughout the treatment process, with particular attention to temperature, pulse, respiratory rate, blood pressure, urine output, electrocardiography (ECG) and O2 saturation.[23] Poison control centers and medical toxicologists are available in many areas to provide guidance in overdoses both to physicians and to the general public.
Antidotes
[edit]
Specific antidotes are available for certain overdoses. For example, naloxone is the antidote for opiates such as heroin or morphine. Similarly, benzodiazepine overdoses may be effectively reversed with flumazenil. As a nonspecific antidote, activated charcoal is frequently recommended if available within one hour of the ingestion and the ingestion is significant.[24] Gastric lavage, syrup of ipecac, and whole bowel irrigation are rarely used.[24]
Epidemiology and statistics
[edit]
Further information: US drug overdose death rates and totals over time
A two milligram dose of fentanyl powder (on pencil tip) is a lethal amount for most people.[25]
The UN gives a figure of 300,000 deaths per year in the world through drug overdose.
1,015,060 US residents died from drug overdoses from 1968 to 2019. 22 people out of every 100,000 died from drug overdoses in 2019 in the US.[26] From 1999 to Feb 2019 in the United States, more than 770,000 people have died from drug overdoses.[27]
In the US around 107,500 people died in the 12-month period ending August 31, 2022, at a rate of 294 deaths per day.[28] 70,630 people died from drug overdoses in 2019.[29] The U.S. drug overdose death rate has gone from 2.5 per 100,000 people in 1968 to 21.5 per 100,000 in 2019.[26]
The National Center for Health Statistics reports that 19,250 people died of accidental poisoning in the U.S. in the year 2004 (eight deaths per 100,000 population).[30]
In 2008 testimony before a Senate subcommittee, Leonard J. Paulozzi,[31] a medical epidemiologist at the Centers for Disease Control and Prevention said that in 2005 more than 22,000 American people died due to overdoses, and the number is growing rapidly. Paulozzi also testified that all available evidence suggests unintentional overdose deaths are related to the increasing use of prescription drugs, especially opioid painkillers.[32] However, the vast majority of overdoses are also attributable to alcohol. It is very rare for a victim of an overdose to have consumed just one drug. Most overdoses occur when drugs are ingested in combination with alcohol.[33]
Drug overdose was the leading cause of injury death in 2013. Among people 25 to 64 years old, drug overdose caused more deaths than motor vehicle traffic crashes. There were 43,982 drug overdose deaths in the United States in 2013. Of these, 22,767 (51.8%) were related to prescription drugs.[34]
The 22,767 deaths relating to prescription drug overdose in 2013, 16,235 (71.3%) involved opioid painkillers, and 6,973 (30.6%) involved benzodiazepines. Drug misuse and abuse caused about 2.5 million emergency department (ED) visits in 2011. Of these, more than 1.4 million ED visits were related to prescription drugs. Among those ED visits, 501,207 visits were related to anti-anxiety and insomnia medications, and 420,040 visits were related to opioid analgesics.[35]
