Doctors prescribe morphine sulfate to treat severe acute and chronic pain. This medication is to be used by patients whose pain does not respond to non-opioid pain relievers and who need pain relief for more than a few days. A physician may recommend morphine sulfate to patients experiencing dyspnea associated with acute left ventricular failure, which is difficulty breathing as a result of the type of heart failure. Morphine sulfate may be used for sedation before surgery, along with anesthesia or to provide pain relief during labor. This medication should be used only by patients who are already tolerant to opioids; this means a patient should have already been taking another narcotic pain reliever for at least several days before taking morphine sulfate.

Morphine sulfate works by stimulating opioid receptors in the central nervous system. This drug also causes respiratory depression, a condition where there is not enough air flow to perform the needed gas exchange. Morphine sulfate also causes peripheral dilation, slows down movement in the intestines, spasm of the sphincter which controls digestive juices and increases bladder tone. Morphine sulfate stimulates chemoreceptors in a way that causes vomiting. It takes 15 to 60 minutes for oral preparations of morphine sulfate to begin working. Pain relief typically lasts 3 to 7 hours. Morphine sulfate delivered through an epidural usually relieves pain within 6 to 30 minutes with pain relief lasting 16 to 24 hours from a single epidural injection.

Morphine sulfate is one of the most widely abused of all drugs. Recreational users favor morphine because of the way it gets them high. Others may abuse morphine because they became addicted to this powerful opioid as part of a treatment for acute or chronic pain. Abusers can acquire morphine by filing bogus prescriptions, going to multiple doctors or by stealing from friends, family members, pharmacies or strangers. Morphine is also widely available on the streets.

Withdrawal is a predictable, normal physiological response to taking high doses of opioids or taking them for a long time. Your body goes through withdrawal because it has grown dependent on morphine to feel normal. Withdrawal symptoms can vary in intensity from person to person; withdrawal may be severe enough to prevent some people from quitting morphine. Withdrawal symptoms include:
Dependence to morphine sulfate is a complex condition; you may need the help of qualified rehabilitation professionals. The most effective rehabilitative treatment programs address each aspect of the complicated syndrome of drug dependence, including overcoming withdrawal symptoms, detoxifiying your body and then addressing any social issues that contributed to your dependence on morphine. During the first phase of rehabilitation, physicians administer medication to remove the morphine from your body. Other medications ease your withdrawal symptoms. Once you are physically stabile, you can participate in counseling programs or other social services to address any issues that contributed to or are the result of your dependence on drugs, such as family problems or legal issues. Rapid detox is the most advanced, state-of-the-art, humane and extremely effective way to overcome withdrawal. During rapid detox, specially trained and highly qualified physicians administer anesthesia and sedatives along with detoxification medications. You sleep serenely through the withdrawal process, unaware of the unpleasant symptoms associated with withdrawal. When you awaken, you will have no memory of the withdrawal process.

The manufacturers of oral solution of morphine sulfate, Roxane Laboratories, and the FDA notified healthcare professionals about serious adverse effects and even deaths resulting from overdose, especially when using the high-dose, 100 mg/5 ml oral solution.
