Descriptions


Morphine and naltrexone combination is used to treat moderate to severe pain when around-the-clock pain relief is needed for a long period of time. This medicine should not be used to treat pain that you only have once in a while, or pain that can be relieved with non-narcotic medication.

Morphine is a narcotic analgesic (pain medicine). It acts on the central nervous system (CNS) to relieve pain.

Naltrexone is an opioid antagonist. It blocks the effects of narcotics, especially the "high'' feeling that makes you want to use them. It will not produce any narcotic-like effects or cause mental or physical dependence.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Capsule, Extended Release

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of morphine and naltrexone combination in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of morphine and naltrexone combination in the elderly. However, elderly patients are more likely to have age-related heart, kidney, liver, or lung problems, which may require caution and an adjustment in the dose for patients receiving morphine and naltrexone combination.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve dizziness or lightheadedness.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Symptoms of an overdose include extreme dizziness or weakness, shortness of breath, slow heartbeat, seizures, and cold, clammy skin. Call your doctor right away if you notice these symptoms.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine. Serious side effects can occur if your medical doctor or dentist gives you certain other medicines without knowing that you are using morphine and naltrexone combination.

This medicine may make you dizzy, drowsy, or lightheaded. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous until you know how this medicine affects you.

This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

If you have been using this medicine regularly for several weeks or more, do not suddenly stop using it without first checking with your doctor. You may be directed to gradually reduce the amount you are using before stopping treatment completely, or to take another narcotic for a while, to lessen the chance of withdrawal side effects.

Tell your doctor if you are pregnant or plan to become pregnant while taking this medication. Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn baby, which can be life-threatening. Tell your doctor right away if your baby has the following symptoms: abnormal sleep pattern, diarrhea, high-pitched cry, irritability, shakiness or tremor, weight loss, vomiting, or failure to gain weight.
