Morphine is an opioid pain medication. An opioid is sometimes called a narcotic. It is used to treat moderate to severe pain. Short-acting formulations are taken as needed for pain. The extended-release form of this medicine is for around-the-clock treatment of pain. This form of morphine is not for use on an as-needed basis for pain. Morphine is not for treating short-term pain just after surgery unless you were already taking morphine before the surgery. You should not take morphine if you have severe asthma or breathing problems, a blockage in your stomach or intestines, or a bowel obstruction called paralytic ileus. Morphine can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Morphine may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away morphine to any other person is against the law.

Common morphine side effects may include: drowsiness, dizziness; constipation, stomach pain, nausea, vomiting; headache, tired feeling; anxiety; or mild itching.
