Drug overdose

The word "overdose" implies that there is a common safe dosage and usage for the drug; therefore, the term is commonly applied only to drugs, not poisons, even though many poisons as well are harmless at a low enough dosage. Drug overdose is sometimes used as a means to commit suicide, as the result of intentional or unintentional misuse of medication. Intentional misuse leading to overdose can include using prescribed or non-prescribed drugs in excessive quantities in an attempt to produce euphoria.

Usage of illicit drugs, in large quantities, or after a period of drug abstinence can also induce overdose. Cocaine and opioid users who inject intravenously can easily overdose accidentally, as the margin between a pleasurable drug sensation and an overdose is small.Study on [http://www.biomedcentral.com/1471-2458/7/31 fatal overdose] {{webarchive|url=https://web.archive.org/web/20120119041854/http://www.biomedcentral.com/1471-2458/7/31 |date=January 19, 2012 }} in New-York City 1990-2000, visited May 11, 2008, Unintentional misuse can include errors in dosage caused by failure to read or understand product labels.

The term 'overdose' is often misused as a descriptor for adverse drug reactions or negative drug interactions due to mixing multiple drugs simultaneously.

Signs and symptoms of an overdose vary depending on the drug or exposure to toxins. The symptoms can often be divided into differing toxidromes. This can help one determine what class of drug or toxin is causing the difficulties.

Symptoms of opioid overdoses include slow breathing, heart rate and pulse.{{cite web |last=Chandler |first=Stephanie |title=Symptoms of an opiate overdose |url=http://www.livestrong.com/article/68582-symptoms-opiate-overdose/ |publisher=Live Strong |access-date=May 17, 2012 |url-status=live |archive-url=https://web.archive.org/web/20120418164856/http://www.livestrong.com/article/68582-symptoms-opiate-overdose/ |archive-date=April 18, 2012}} Opioid overdoses can also cause pinpoint pupils, and blue lips and nails due to low levels of oxygen in the blood. A person experiencing an opioid overdose might also have muscle spasms, seizures and decreased consciousness. A person experiencing an opiate overdose usually will not wake up, even if their name is called or they are shaken vigorously.

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.{{Cite web |url=https://www.tmz.com/2010/09/02/t-i-arrest-sizzurp-drugs-controlled-substance-tiny-codeine/ |title=T.I.

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.[http://www.preskorn.com/columns/0207.html "Column—Fatal Drug-Drug Interaction As a Differential Consideration in Apparent Suicides"] {{webarchive|url=https://web.archive.org/web/20080223185230/http://www.preskorn.com/columns/0207.html |date=February 23, 2008 }}.

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.{{cite book |title=Oxford Handbook of Clinical Medicine |last=Longmore |first=Murray |author2=Ian Wilkinson |author3=Tom Turmezei |author4=Chee Kay Cheung |year=2007 |publisher=Oxford |location=United Kingdom |isbn=978-0-19-856837-7}} Poison control centers and medical toxicologists are available in many areas to provide guidance in overdoses both to physicians and to the general public.

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.{{cite journal |last=Vanden Hoek |first=TL |author2=Morrison, LJ |author3=Shuster, M |author4=Donnino, M |author5=Sinz, E |author6=Lavonas, EJ |author7=Jeejeebhoy, FM |author8=Gabrielli, A |title=Part 12: cardiac arrest in special situations: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care |journal=Circulation |date=November 2, 2010 |volume=122 |issue=18 Suppl 3 |pages=S829–61 |pmid=20956228 |doi=10.1161/CIRCULATIONAHA.110.971069 |doi-access=free}} Gastric lavage, syrup of ipecac, and whole bowel irrigation are rarely used.
