Warnings:

Morphine has a risk for abuse and addiction, which can lead to overdose and death. Morphine may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you take the smallest dose of morphine that works, and take it for the shortest possible time. See also How to Use section for more information about addiction.

The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you take the wrong dose/strength. Taking this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Be sure you know how to take morphine and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.

Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, take the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms.

This medication is used to help relieve severe ongoing pain (such as due to cancer). Morphine belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain.The higher strengths of this drug (100 milligrams or more per tablet) should be used only if you have been regularly taking moderate to large amounts of opioid pain medications. These strengths may cause overdose (even death) if taken by a person who has not been regularly taking opioids.Do not use the extended-release form of morphine to relieve pain that is mild or that will go away in a few days. This medication is not for occasional ("as needed") use.

Ask your doctor or pharmacist about other ways to decrease nausea (such as lying down for 1 to 2 hours with as little head movement as possible). If nausea persists, see your doctor.
