What you need to know about morphine capsules (Morphine Sustained-Release) for severe pain

You may have noticed that the name of this medicine says 'Sustained-Release'. This means that when you take this medicine, the medicine is gradually released into the body and lasts for several hours, meaning it works for a long time . Therefore, it is used for long-term pain, not for sudden pain.

Even after giving Naloxone, immediate hospitalization is essential.
