"Painkiller" is a term commonly used to describe medications that help alleviate pain. These drugs can be classified into various categories, including over-the-counter options like acetaminophen and ibuprofen, as well as prescription medications such as opioids. Painkillers work by blocking pain signals in the brain or reducing inflammation in the body. The use of painkillers has become a significant topic in healthcare due to concerns about addiction, especially with opioids. While they can provide relief for conditions like chronic pain or post-surgical discomfort, it is essential to use them responsibly and under medical supervision to minimize risks and side effects.
