Astramorph treats pain that is not relieved by non narcotic pain relievers.

Astramorph Overview

Updated: 

Astramorph is a prescription medication used to treat pain that is not relieved by non narcotic pain relievers. 

It belongs to a group of drugs called opioid narcotics. These work by changing the way the brain and nervous system respond to pain.

This medication is available as an injection to be given into the vein (IV) by a healthcare professional. It can also be administered epidurally (into the epidural space) or intrathecally (within the spinal canal).

Common side effects of Astramorph include constipation, nausea, itchiness, and sleepiness. Do not drink alcohol or any foods or medications containing alcohol while receiving Astramorph as alcohol increases the risk that you will experience breathing problems or other serious, life-threatening side effects.

Astramorph Precautions

Astramorph may be habit-forming. There is a greater risk that you will overuse Astramorph if you have or have ever had depression or another mental illness, or if you have abused alcohol, used street drugs, or overused prescription medications.

Astramorph may cause slowed or stopped breathing, especially when you begin your treatment and any time your dose is increased. Tell your doctor if you have slowed breathing and if you have or have ever had lung disease such as asthma, chronic obstructive pulmonary disease (COPD; a group of diseases including chronic bronchitis and emphysema that cause difficulty breathing), or other breathing problems. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.

Taking certain other medications during your treatment with Astramorph may increase the risk that you will experience breathing problems or other serious, life-threatening side effects.

Do not receive Astramorph if you have:

  • severe asthma, trouble breathing, or other lung problems.
  • a bowel blockage or have narrowing of the stomach or intestines.

While receiving Astramorph do not:

  • Drive or operate heavy machinery, until you know how Astramorph affects you. Astramorph can make you sleepy, dizzy, or lightheaded.
  • Drink alcohol or use prescription or over-the-counter medicines that contain alcohol.

Astramorph Food Interactions

Medicines can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods. In the case of Astramorph there are no specific foods that you must exclude from your diet when receiving this medication.

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements.

Astramorph and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

This medication falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Astramorph and Lactation

Tell your healthcare provider if you are breastfeeding. Astramorph passes into human breast milk and may harm your baby.

Astramorph Usage

This medication is available as an injection to be given into the vein (IV) by a healthcare professional. It can also be administered epidurally (into the epidural space) or intrathecally (within the spinal canal).

If you feel that your pain is not controlled, inform your physician. 

Astramorph Dosage

The dose your doctor recommends may be based on the following:

  • the type and severity of the pain you have
  • other medical conditions you have
  • how you respond to this medication
  • your weight

Astramorph Overdose

Astramorph is usually administered by a healthcare provider in a medical setting making it unlikely for an overdose to occur. However, if overdose is suspected, seek emergency medical attention.

Other Requirements

Do not miss your follow-up appointment with your doctor.

Astramorph FDA Warning

Astramorph may be habit forming. Overdoses may cause respiratory depression, coma and death.

Astramorph administration should be limited to use by those familiar with the management of respiratory depression. Rapid intravenous administration may result in chest wall rigidity.

Prior to any epidural or intrathecal drug administration, the physician should be familiar with patient conditions (such as infection at the injection site, bleeding diathesis, anticoagulant therapy, etc.) which call for special evaluation of the benefit versus risk potential.

SEVERE RESPIRATORY DEPRESSION UP TO 24 HOURS FOLLOWING EPIDURAL OR INTRATHECAL ADMINISTRATION HAS BEEN REPORTED.

In the case of epidural or intrathecal administration, Astramorph should be administered by or under the direction of a physician experienced in the techniques and familiar with the patient management problems associated with epidural or intrathecal drug administration. Because epidural administration has been associated with less potential for immediate or late adverse effects than intrathecal administration, the epidural route should be used whenever possible. 

BECAUSE OF THE RISK OF SEVERE ADVERSE EFFECTS WHEN THE EPIDURAL OR INTRATHECAL ROUTE OF ADMINISTRATION IS EMPLOYED, PATIENTS MUST BE OBSERVED IN A FULLY EQUIPPED AND STAFFED ENVIRONMENT FOR AT LEAST 24 HOURS AFTER THE INITIAL DOSE.

THE FACILITY MUST BE EQUIPPED TO RESUSCITATE PATIENTS WITH SEVERE OPIATE OVERDOSAGE, AND THE PERSONNEL MUST BE FAMILIAR WITH THE USE AND LIMITATIONS OF SPECIFIC NARCOTIC ANTAGONISTS (NALOXONE, NALTREXONE) IN SUCH CASES.

PATIENTS SOMETIMES MANIFEST UNUSUAL ACCELERATION OF NEURAXIAL ASTROMORPH REQUIREMENTS, WHICH MAY CAUSE CONCERN REGARDING SYSTEMIC ABSORPTION AND THE HAZARDS OF LARGE DOSES; THESE PATIENTS MAY BENEFIT FROM HOSPITALIZATION AND DETOXIFICATION. TWO CASES OF MYOCLONIC-LIKE SPASM OF THE LOWER EXTREMITIES HAVE BEEN REPORTED IN PATIENTS RECEIVING MORE THAN 20 MG/DAY OF INTRATHECAL ASTROMORPH. AFTER DETOXIFICATION, IT MIGHT BE POSSIBLE TO RESUME TREATMENT AT LOWER DOSES, AND SOME PATIENTS HAVE BEEN SUCCESSFULLY CHANGED FROM CONTINUOUS EPIDURAL ASTROMORPH TO CONTINUOUS INTRATHECAL ASTROMORPH. REPEAT DETOXIFICATION MAY BE INDICATED AT A LATER DATE. THE UPPER DAILY DOSAGE LIMIT FOR EACH PATIENT DURING CONTINUING TREATMENT MUST BE INDIVIDUALIZED.
