Morphine pour soulager la douleur

About morphine

What is morphine used for?

Morphine is a analgésique opioïde puissant that is used to treat severe or long-term (chronic) pain when weaker painkillers are not effective.

It is most commonly used for pain after surgery, serious injury, or in conditions such as cancer-related pain.

Morphine works by acting on the brain and nervous system to reduce how much pain you feel.

What is morphine available as?

Morphine is available in several forms, including:

• Liquid or tablets taken by mouth.

• Slow-release tablets or capsules for long-lasting pain relief.

• Injections, which are often used in hospitals, especially after surgery.

There are different brands of oral morphine, and they are not all absorbed by the body in the same way. Once you start taking one brand, you should continue with the same one unless your doctor advises a change.
