Analgesics are medications designed to relieve pain. They work by blocking pain signals in the brain or reducing inflammation in the body. Common types of analgesics include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and opioids such as morphine. These medications can be used for various types of pain, including headaches, muscle aches, and post-surgical discomfort. While many analgesics are available over-the-counter, some require a prescription due to their potential for addiction or side effects. It's important to use them as directed to ensure safety and effectiveness.
