Morphine: Uses, Side Effects, and Drug Interactions

# Morphine: What You Need to Know Morphine is a powerful pain medication that doctors use to treat moderate to severe pain, especially in patients who have been seriously injured, had surgery, or have cancer. It works by changing the way your body feels and responds to pain. Morphine comes in different forms, including tablets, liquids, and extended-release versions that slowly release medicine over time. Because morphine is very strong, it should only be used exactly as a doctor prescribes it. Morphine is a controlled substance, which means the government carefully monitors its use because people can become dependent on it if they take it for too long or use it incorrectly. It's very important not to mix morphine with alcohol or other drugs that make you sleepy or drowsy, like certain anxiety medications, because this combination can be extremely dangerous and even life-threatening. Common side effects include drowsiness, constipation, and nausea. Always tell your doctor about all the medications you take, and never share your morphine with anyone else, even if they have similar pain. If you have questions about your morphine prescription, talk to your pharmacist or doctor—never change how much you take or how often you take it without their permission.
