Acetaminophen, widely known as paracetamol, is an analgesic and antipyretic drug used to relieve mild to moderate pain and fever. Paracetamol is one of the most common over-the-counter drugs. It can be used across all age groups, including infants, the elderly, and both pregnant and lactating women. Paracetamol is often combined with other drugs to provide synergistic effects for patients. Some popular brand names of paracetamol include CROCIN, METACIN, and PARACETAMOL RECTAL SUPPOSITORY.
