Pain Home > Avinza Uses

Avinza is used for treating moderate to severe chronic pain that requires around-the-clock pain relief. It comes in the form of capsules that contain tiny extended-release beads that are specially designed to release morphine evenly throughout the day, allowing for once-daily dosing. There are currently no approved Avinza uses for children.

What Is Avinza Used For?

Avinza® (morphine sulfate ER) is a prescription medication approved to treat chronic moderate to severe pain.
 
Avinza is meant to be taken every day on a regular schedule. It is not approved for "as needed" use (unscheduled use only when needed) or for short-term use. Avinza is not appropriate for treating pain after a surgery, unless you were already taking Avinza before the surgery. People who are unaccustomed to taking opioid medications should not take the higher-strength capsules (60, 90, and 120 mg).
 
Avinza is used to provide a steady "background" level of pain relief. Often, people need to take additional short-acting "rescue" painkillers in addition to Avinza for "breakthrough" pain. Because Avinza contains morphine, it can be used (or rather, abused) inappropriately (see Avinza Abuse).
 

How Does Avinza Work?

Avinza capsules contain tiny extended-release beads that are specially designed to release morphine evenly throughout the day, allowing for once-daily dosing.
 
Morphine is an opioid narcotic medication. It binds to opioid receptors throughout the body and produces a number of different effects, some desirable (such as pain control) and some undesirable (such as itching). These effects include, but are not limited to:
 
  • Pain relief
  • Cough suppression
  • Unusual unpleasant feelings (dysphoria) or unusual pleasant feelings (euphoria)
  • Slowing of the digestive tract
  • Drowsiness
  • Release of histamine (which often causes itching)
  • Decreased breathing (slow or shallow breathing)
  • Certain changes in the circulatory system
  • Physical dependence.
