Morphine Sulfate/Naltrexone Hydrochloride
Morphine sulfate/naltrexone hydrochloride is a type of narcotic primarily used for relieving pain. This prescription medication contains tiny, extended-release beads that release morphine evenly throughout the day. Each bead contains a dose of naltrexone, which counteracts the effects of morphine if the drug is taken incorrectly (such as if it is crushed or dissolved in order to snort or inject the medication). Common side effects include constipation and drowsiness.
Morphine sulfate/naltrexone hydrochloride (Embeda™) is a long-acting prescription pain medication. It is specially formulated in such a way as to reduce the potential for abuse (especially for abuse by crushing and snorting or injecting the medication).
