Tylenol is a brand of medication primarily used to reduce pain and fever. Its active ingredient is acetaminophen (also known as paracetamol), which acts as an analgesic (pain reliever) and antipyretic (fever reducer). Tylenol is commonly used for conditions such as headaches, muscle aches, arthritis, menstrual cramps, colds, and flu-related discomforts. It is available in various forms including tablets, liquids, and chewables. Tylenol is not an anti-inflammatory drug like ibuprofen but is often preferred for people who cannot tolerate nonsteroidal anti-inflammatory drugs (NSAIDs). It should be used with caution to avoid overdose, as excessive intake can cause severe liver damage.
