Uses for morphine

Morphine epidural injection is used to relieve pain following a major surgery. It is given right before a surgery or during a cesarean section delivery right after the baby's umbilical cord is clamped.

This medicine is available only with your doctor's prescription and will be given by or under the immediate supervision of your doctor.

Before using morphine

Pediatric
