Dictionary

Painkillers are drugs used to relieve pain. They come in many forms, including over-the-counter (OTC) versions such as acetaminophen and ibuprofen and prescription medications such as opioids and non-steroidal anti-inflammatory drugs (NSAIDs). Painkillers work by blocking pain signals from reaching the brain, reducing inflammation, or changing how the brain perceives pain.

They are commonly used to treat a wide range of conditions, including headaches, menstrual cramps, arthritis, back pain, and cancer pain. However, many painkillers, especially opioids, are addictive and have a high potential for abuse and overdose, especially when taken in large doses or used for non-medical purposes. It is important to use painkillers only as directed by a healthcare provider and to be aware of their potential risks and side effects.
