The most commonly used painkiller is Tylenol.

First of all, it's because the most widely known and easily accessible fever reducer and painkiller is used habitually in urgent situations. When raising a child, there are times when they suddenly develop a fever or wake up in the morning with a sore throat... in such cases, using it temporarily helps to reduce the fever and relieve the pain, which provides some peace of mind when you can't immediately go to the hospital.

Since it is an analgesic that only has antipyretic effects and no anti-inflammatory action, when inflammation becomes a problem, there are cases where you ultimately need to go to the hospital and use anti-inflammatory analgesics or antibiotics. However, for reducing pain initially, it seems to be the first medication that is primarily used.

And the reason why Tylenol is often considered the first choice as a pain reliever is also because acetaminophen is highly safe and does not cause gastrointestinal issues.

Of course, there are other painkillers containing acetaminophen, but I think it's mainly because of the recognition level that makes it almost synonymous with that ingredient, haha.
