Codeine is an opioid medication often used to relieve mild to moderate pain and to suppress coughing. It works by binding to opioid receptors in the brain and spinal cord. Codeine is less potent than some other opioids, but it can still be habit-forming and has potential side effects, including drowsiness and constipation. It's typically available in combination with other medications, such as acetaminophen or aspirin. Like other opioids, codeine should be used only as directed by a healthcare professional to minimize the risk of misuse and dependence. It’s available in different types like 15mg, 30mg, 300/30mg, and 60mg.
