PCM 500 Tablet is used to relieve pain and reduce fever. It contains Paracetamol (also known as Acetaminophen), a widely used analgesic (pain reliever) and antipyretic (fever reducer). It is effective in easing mild to moderate pain, such as headaches, toothaches, body aches, joint pain, and muscle discomfort. Paracetamol works by blocking the action of certain chemical messengers (prostaglandins) in the brain that transmit pain signals and regulate body temperature. This helps provide reliable and effective relief, improving comfort and overall well-being when used as directed.
