What is the most important information I should know about morphine and naltrexone (Embeda)?
You should not use morphine and naltrexone if you have ever had an allergic reaction to a narcotic medicine, if you are having an asthma attack or if you have a bowel obstruction called paralytic ileus.
Do not use morphine and naltrexone if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.
Before taking morphine and naltrexone, tell your doctor if you have a breathing disorder, liver or kidney disease, low blood pressure, a thyroid disorder, curvature of the spine, gallbladder or pancreas disorders, a blockage in your stomach or intestines, Addison's disease, enlarged prostate, urination problems, a seizure disorder, a debilitating condition, mental illness, a history of head injury or brain tumor, or a history of alcoholism or drug addiction.
Morphine and naltrexone may cause addiction or withdrawal symptoms in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using morphine and naltrexone.
You should not breast-feed while you are using morphine and naltrexone.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how morphine and naltrexone will affect you. Do not take morphine and naltrexone with other medicines that can make you sleepy or slow your breathing. Dangerous side effects may result.
Do not drink alcohol while you are using this medication. Dangerous side effects or death can occur when alcohol is combined with morphine and naltrexone. Check your food and medicine labels to be sure these products do not contain alcohol.
Do not crush, chew, or dissolve the medicine pellets inside an extended-release capsule. If possible, swallow the pill whole. Crushing or chewing the medicine pellets would cause too much of the drug to be released at one time, which may cause a life-threatening overdose.
Never take morphine and naltrexone in larger amounts, or for longer than recommended by your doctor. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
