Paracetamol (also known as acetaminophen) is one of the most widely used medicines globally for pain relief and fever reduction. Understanding its appropriate use and important precautions can help you use it safely under medical guidance.
Paracetamol (acetaminophen) is an analgesic (pain reliever) and antipyretic (fever reducer) that works by inhibiting prostaglandin synthesis in the central nervous system. It is a first-line medicine for mild to moderate pain and fever and is widely available in Korea at pharmacies without a prescription. Common brand names in Korea include Panadol, Tylenol, and Calpol (paediatric liquid formulation).
Paracetamol is used for a range of conditions including headache, dental pain, muscle aches, arthritis, menstrual pain, and fever management in adults and children. It is generally preferred over NSAIDs (such as ibuprofen) in patients with peptic ulcers, kidney disease, or cardiovascular risk — as it does not irritate the stomach lining or affect blood pressure in therapeutic doses.
Despite being widely available, paracetamol requires careful use. The most serious risk is liver toxicity from overdose — even an inadvertent overdose from taking multiple products that each contain paracetamol can cause severe, potentially fatal liver damage. Patients should always check that they are not taking paracetamol in multiple products simultaneously. Liver risk is significantly increased by regular alcohol consumption.
Always consult a doctor or pharmacist before using paracetamol if you have liver disease, take blood thinners, or are unsure about the appropriate formulation for a child.
