Painkillers, also known as analgesics, are medications that help alleviate or reduce pain. They work by interfering with the transmission of pain signals to the brain or by reducing inflammation that causes pain. Common types of painkillers include acetaminophen (such as Tylenol), nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofen, and naproxen, and opioid painkillers such as codeine, morphine, and oxycodone. Painkillers are available in different forms, including tablets, capsules, liquids, creams, and patches. It is important to use painkillers according to the instructions provided and to consult a healthcare professional before taking them, especially if you have a medical condition or are taking other medications.
