USES: This medication is used to help relieve moderate to severe ongoing pain (such as due to cancer). Morphine belongs to a class of drugs known as narcotic (opiate) analgesics. It works in the brain to change how your body feels and responds to pain.The higher strengths of this drug (90 and 120 milligrams per capsule) should be used only if you have been regularly taking moderate to large amounts of narcotic pain medication. These strengths may cause overdose (even death) if taken by a person who has not been regularly taking narcotic medication.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.
HOW TO USE: See also Warning section.Read the Medication Guide provided by your pharmacist before you start using morphine and each time you get a refill. If you have any questions, consult your doctor or pharmacist.Take this medication on a regular schedule as directed by your doctor, not as needed for sudden (breakthrough) pain. Take this drug with or without food, usually once daily (every 24 hours). If you have nausea, it may help to take this drug with food. 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).Swallow the capsules whole. Adults who have trouble swallowing the capsule may open the capsule and carefully sprinkle its contents on a spoonful of soft, cool applesauce. Swallow all of the drug/food mixture immediately without chewing. Then rinse your mouth and swallow the rinse liquid to make sure that you have swallowed all of the dose. Do not chew the mixture or prepare a supply in advance. Do not give this medication to a child this way, since they might chew the mixture and overdose. For children who have trouble swallowing the capsule, ask the doctor about using a different form of morphine instead.Because of the risk for overdose, do not give this medication down a feeding tube.The dosage is based on your medical condition and response to treatment. Do not increase your dose, take the medication more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.The maximum recommended dose of this medication is 1600 milligrams per 24-hour period.
