In the USA, paracetamol is known as acetaminophen. Acetaminophen is a non-opioid analgesic and antipyretic agent used to treat mild-to-moderate pain, headache, and fever. It is available as brand names such as Tylenol, Mapap, or Panadol, and also as generics and store-specific brands. There are no differences in the chemical structure or therapeutic uses of acetaminophen and paracetamol, although recommended doses and available strengths may vary slightly between countries. Acetaminophen comes in many over-the-counter (OTC) forms in the U.S., including regular (325 mg) and extra-strength (500 mg) oral tablets or capsules, rapid-release, oral liquids, chewable or orally-disintegrating tablets, and rectal suppositories.
