AUDIENCE: Family Practice, Psychiatry, Pain Management, Nursing, Endocrinology
ISSUE: FDA is warning about several safety issues with the entire class of opioid pain medicines. See the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm for a complete listing. These safety risks are potentially harmful interactions with numerous other medications, problems with the adrenal glands, and decreased sex hormone levels. We are requiring changes to the labels of all opioid drugs to warn about these risks.
BACKGROUND: Opioids are powerful prescription medicines that can help manage pain when other treatments and medicines are not able to provide enough pain relief (see List of Opioid Medicines in the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm ). However, opioids also carry serious risks, including of misuse and abuse, addiction, overdose, and death.
Prescription opioids are divided into two main categories – immediate-release (IR) products, usually intended for use every 4 to 6 hours; and extended release/long acting (ER/LA) products, intended to be taken once or twice a day, depending on the individual product and patient.
See the http://www.fda.gov/Drugs/DrugSafety/ucm489676.htm for additional information, including a listing of opioids, serotonergic medicines, and a data summary.
Health care professionals should discontinue opioid treatment and/or use of the other medicine if serotonin syndrome is suspected.
Health care professionals should perform diagnostic testing if adrenal insufficiency is suspected. If diagnosed, treat with corticosteroids and wean the patient off of the opioid, if appropriate. If the opioid can be discontinued, follow-up assessment of adrenal function should be performed to determine if treatment with corticosteroids can be discontinued.
Decreased sex hormone levels:
Health care professionals should conduct laboratory evaluation in patients presenting with such signs or symptoms.

Morphine may cause serious or life-threatening breathing problems, especially at the beginning of your treatment and any time your dose is increased. Your doctor will monitor you carefully during your treatment. Your doctor will adjust your dose carefully to control your pain and decrease the risk that you will experience serious breathing problems. Tell your doctor if you have or have ever had slowed breathing or asthma. Your doctor may tell you not to take morphine. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of lung diseases that includes chronic bronchitis and emphysema), a head injury, any condition that increases the amount of pressure in your brain, or kyphoscoliosis (curving of the spine that may cause breathing problems). The risk that you will develop breathing problems may be higher if you are an older adult or are weakened or malnourished due to disease. 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 morphine may increase the risk that you will experience breathing problems or other serious, life-threatening side effects. Tell your doctor if you are taking or plan to take any of the following medications: cimetidine (Tagamet); other narcotic pain medications; medications for anxiety, seizures, depression, mental illness, or nausea; muscle relaxants; sedatives; sleeping pills; or tranquilizers.
Drinking alcohol, taking prescription or non-prescription medications that contain alcohol, or using street drugs during your treatment with morphine increases the risk that you will experience breathing problems or other serious, life-threatening side effects. If you are taking Avinza brand long-acting capsules, it is especially important that you do not drink any drinks that contain alcohol or take any prescription or non-prescription medications that contain alcohol. Alcohol may cause the morphine in Avinza
Morphine may be habit-forming. Do not take more of it, take it more often, or take it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse morphine if you have or have ever had any of these conditions.
Do not allow anyone else to take your medication. Morphine may harm or cause death to other people who take your medication, especially children. Keep morphine in a safe place so that no one else can take it accidentally or on purpose. Be especially careful to keep morphine out of the reach of children. Keep track of how many tablets, or capsules, or how much liquid is left so you will know if any medication is missing.Dispose of any unneeded morphine capsules, tablets, or liquid properly according to instructions. (See STORAGE and DISPOSAL.)
Swallow the extended-release tablets or capsules whole. Do not split, chew, dissolve, or crush them. If you swallow broken, chewed, crushed, or dissolved extended-release tablets or capsules, you may receive too much morphine at once instead of receiving the medication slowly over time. This may cause serious breathing problems or death. If you are unable to swallow the capsules whole, follow the instructions in the ''HOW should this medication be used?'' section below to dissolve the capsule contents in applesauce.
Morphine oral solution (liquid) comes in three different concentrations (amount of medication contained in a given amount of solution). The solution with the highest concentration (100 mg/5 mL) should only be taken by people who are tolerant (used to the effects of the medication) to opioid medications. Each time you receive your medication, check to be sure that you receive the solution with the concentration prescribed by your doctor. Be sure that you know how much medication you should take and how to measure your dose.
Tell your doctor if you are pregnant or plan to become pregnant. If you take morphine regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with morphine and each time you fill your prescription if a Medication Guide is available for the morphine product you are taking. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
WHY is this medicine prescribed?
Morphine is used to relieve moderate to severe pain. Morphine extended-release tablets and capsules are only used to relieve severe (around-the-clock) pain that cannot be controlled by the use of other pain medications. Morphine extended-release tablets and capsules should not be used to treat pain that can be controlled by medication that is taken as needed. Morphine is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
HOW should this medicine be used?
Morphine comes as a tablet, a solution (liquid), an extended-release (long-acting) tablet, and as an extended-release (long-acting) capsule to take by mouth. The regular tablet and oral solution are usually taken every 4 hours as needed for pain. MS Contin brand long-acting tablets are usually taken every 8 hours or every 12 hours. Kadian brand long-acting capsules are usually taken with or without food every 12 hours or every 24 hours. Avinza brand long-acting capsules are usually taken once a day. 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 long-acting 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 long-acting capsules (Avinza, 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.
Your doctor may start you on a low dose of morphine and gradually increase your dose until your pain is controlled. Your doctor may adjust your dose at any time during your treatment if your pain is not controlled. If you feel that your pain is not controlled, call your doctor. Do not change the dose of your medication without talking to your doctor.
Do not stop taking morphine without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop taking morphine, you may experience withdrawal symptoms such as restlessness; teary eyes; runny nose; yawning; irritability; anxiety; sweating; difficulty falling asleep or staying asleep; chills; back, muscle, or joint pain; nausea; vomiting; loss of appetite; diarrhea; stomach cramps; weakness; fast heartbeat; or fast breathing.
Are there OTHER USES for this medicine?
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
