Prescription painkillers are medications specifically prescribed by healthcare professionals to help manage moderate to severe pain. They work by altering the way the brain and nervous system respond to pain signals. Common types include opioids, such as morphine and oxycodone, as well as non-opioid medications like acetaminophen and NSAIDs (non-steroidal anti-inflammatory drugs). These medications are typically used after surgeries, injuries, or for chronic pain conditions. While they can be effective in providing relief, they also carry risks, including potential for addiction and side effects. Therefore, they should be used under strict medical supervision.
