Morphabond brand extended-release tablets are usually taken every 12 hours. Kadian brand extended-release capsules are usually taken with or without food every 12 hours or every 24 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
If you are taking morphine solution, use the dosing cup or syringe that comes with the medication to measure your dose. Be sure that you know how many milliliters of the liquid you should take. Ask your pharmacist if you have any question about how much medication you should take or how to use the dosing cup or syringe.
If you are taking Kadian brand extended-release capsules and you have a gastrostomy tube (surgically inserted feeding tube), ask your doctor or pharmacist how to administer the medication through your tube.
If you are unable to swallow the extended-release capsules (Kadian), you can carefully open a capsule, sprinkle all of the beads that it contains on a spoonful of cold or room temperature applesauce, and swallow the entire mixture immediately without chewing or crushing the beads. Then rinse your mouth with a little water and swallow the water to be sure that you have swallowed all the medication. Do not mix the beads into any other food. Do not save mixtures of medication and applesauce for later.
If you are taking the extended-release tablets (Arymo ER), swallow them one at a time with plenty of water. Swallow the extended-release tablets right after putting it in your mouth. Do not presoak, wet, or lick the extended-release tablets before you put them in your mouth.
