Frequency. >100,000 per year (US) [ 1 ] Paracetamol poisoning, also known as acetaminophen poisoning, is caused by excessive use of the medication paracetamol (acetaminophen). [ 2 ] Most people have few or non-specific symptoms in the first 24 hours following overdose. These symptoms include feeling tired, abdominal pain, or nausea.
[107] [108] A single dose should not exceed 1000 mg, doses should be taken no sooner than four hours apart, and no more than four doses (4000 mg) in 24 hours. [40] While a majority of adult overdoses are linked to suicide attempts, many cases are accidental, often due to the use of more than one paracetamol-containing product over an extended ...
The therapeutic index (TI; also referred to as therapeutic ratio) is a quantitative measurement of the relative safety of a drug. It is a comparison of the amount of a therapeutic agent that causes toxicity to the amount that causes the therapeutic effect. [1] The related terms therapeutic window or safety window refer to a range of doses ...
Non-steroidal anti-inflammatory drugs[1][3] (NSAID) [1] are members of a therapeutic drug class which reduces pain, [4] decreases inflammation, decreases fever, [1] and prevents blood clots. Side effects depend on the specific drug, its dose and duration of use, but largely include an increased risk of gastrointestinal ulcers and bleeds, heart ...
The WHO guidelines recommend prompt oral administration of drugs ("by the mouth") when pain occurs, starting, if the patient is not in severe pain, with non-opioid drugs such as paracetamol (acetaminophen) or aspirin, [1] with or without "adjuvants" such as non-steroidal anti-inflammatory drugs (NSAIDs) including COX-2 inhibitors.
Appearance. An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [ 1 ] Tables of this general type are also available for NSAIDs ...
Timeline of US drug overdose death rates by race and ethnicity. [4] Rate per 100,000 population. 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.
The minimum dosage at which paracetamol causes toxicity usually is 7.5 to 10g in the average person. [2] The lethal dose is usually between 10 g and 15 g. [citation needed] Concurrent alcohol intake lowers these thresholds significantly. Chronic alcoholics may be more susceptible to adverse effects due to reduced glutathione levels. [3]
