Perfalgan is a brand name for paracetamol, also known as acetaminophen, which is a widely used over-the-counter medication for relieving pain and reducing fever. It is available in various forms, including tablets, capsules, liquid suspensions, and as an intravenous solution for hospital use. Perfalgan is particularly noted for its effectiveness in treating mild to moderate pain, such as headaches, muscle aches, arthritis, backache, toothaches, colds, and fevers. It works by inhibiting the production of chemicals in the brain that cause pain and fever, offering relief without causing stomach irritation that is often associated with other pain relievers like NSAIDs (non-steroidal anti-inflammatory drugs). However, it is important to use Perfalgan as directed, as excessive use can lead to serious liver damage.
