Help please, what is morphine used for (i know pain but what kind)?

Morphine: Narcotic analgesics are the most efficacious agents available for relief of pain. Morphine is "strong" or "major" narcotic analgesic which is indicated for moderate to severe pain. Because of concerns about tolerance, physical dependence and addiction, many health professionals are still reluctant to prescribe opioids for chronic pain. Rec.: talk to your pcp for more information.
