Paracetamol, commonly known as acetaminophen in some countries like the US (where it is marketed as Tylenol), is one of the most widely used over-the-counter (OTC) medications globally. In the UK, it’s a household staple for treating a wide range of everyday health issues. Whether you’re dealing with a headache, muscle pain, or fever, paracetamol is often the first line of treatment due to its effectiveness and safety profile.
