Paracetamol, also known as acetaminophen, is a medication used to treat pain and fever. [15] [16] It is typically used for mild to moderate pain relief. [15] Evidence is mixed for its use to relieve fever in children. [17] [18] It is often sold in combination with other medications, such as in many cold medications. [15] Paracetamol is also used for severe pain, such as cancer pain and pain after surgery, in combination with opioid pain medication. [19] It is typically used either by mouth or rectally, but is also available by injection into a vein. [15] [20] Effects last between two and four hours. [20]
Paracetamol is generally safe at recommended doses. [13] [21] The recommended maximum daily dose for an adult is three to four grams. [22] [23] [21] Higher doses may lead to toxicity, including liver failure. [15] Serious skin rashes may rarely occur. [15] It appears to be safe during pregnancy and when breastfeeding. [15] In those with liver disease, it may still be used, but in lower doses. [24] It is classified as a mild analgesic. [20] It does not have significant anti-inflammatory activity. [25] How it works is not entirely clear. [25] [26] [27]
Paracetamol was first made in 1877. [28] It is the most commonly used medication for pain and fever in both the United States and Europe. [29] It is on the World Health Organization's List of Essential Medicines. [30] Paracetamol is available as a generic medication, with brand names including Tylenol and Panadol among others. [31] The wholesale price in the developing world is less than US$0.01 per dose. [32] In the United States, it costs about US$0.04 per dose. [33] In 2017, it was the 25th-most commonly prescribed medication in the United States, with more than 24 million prescriptions. [34] [35]

In postoperative conditions for acute pain of mild to moderate intensity, the quickest reported time to onset of analgesia with APAP is 8 minutes9 for the iv route and 37 minutes6 for the oral route.
