Myths About Morphine

Morphine is an opioid analgesic that offers safe and effective relief of moderate to severe pain. There are many myths about morphine. These myths may affect people’s willingness to accept morphine for pain relief, and may affect the family’s perceptions of why morphine is being prescribed.

There is evidence that nurse’s beliefs about morphine affect their readiness to administer it. [1]
