Morphine is a phenanthrene derivative which acts mainly on the CNS and smooth muscles. It binds to opiate receptors in the CNS altering pain perception and response. Common brand names: Avinza & DepoDur. Morphine is used to help relieve severe pain. Morphine is in a class of medications known as opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain. It is prescribed to relieve moderate to severe pain, especially for around-the-clock relief of pain that cannot be controlled by other pain medications. Knowing how long morphine remains in the system can help prevent an accidental overdose or dangerous interactions with other medications or alcohol. Even though morphine is an FDA-approved medication for pain treatment, its use is associated with serious and sometimes life-threatening side effects—even when taken as prescribed. Side effects most commonly occur within the first 1 to 3 days of taking morphine or whenever a dose is increased 1.
Serious side effects to be aware of include 1:
A bluish or purplish hue to the skin.
Agitation or irritability.
