It appears to reduce pain primarily in the central nervous system by more than one mechanism, possibly in part by inhibiting a form of COX known as COX-3, although this is the subject of much debate. It is, therefore, considered to be a weak analgesic and does not possess anti-inflammatory properties. What this means to you is that acetaminophen is great for headaches, fever and minor aches and pains, but wonât reduce inflammation due to, say, a muscle sprain.
Tylenol also comes in a liquid formula for young children and babies. While the recommended dosages may help relieve pain and fever, giving your baby too much Tylenol can pose certain health risks.
