How It Works

Morphine is an opioid. It acts upon specific receptors in the brain and spinal cord to decrease the feeling of pain and to reduce the emotional response to pain.

Why It Is Used

For a heart attack, morphine is used in the emergency setting to relieve pain.

How Well It Works

Morphine effectively treats moderate to severe pain.

Side Effects

Morphine is given in the hospital. So a person is watched closely for any side effects.

Common side effects of morphine include:

• Trouble breathing.
• Feeling lightheaded or tired.
• Nausea.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
