Description
Paracetamol (acetaminophen) is a widely used over-the-counter analgesic and antipyretic medication (drug class) used to relieve mild-to-moderate pain—such as headaches, muscle aches, and arthritis—and to reduce fever. It is generally safe when used correctly, with common side effects being rare, though improper high doses can cause severe liver damage. It acts centrally to block chemical messengers in the brain.
