Generic Name: morphine (MOR feen)
Brand Names: AVINza, Kadian, MS Contin
What is Kadian?
Kadian (morphine) is an opioid pain medication. An opioid is sometimes called a narcotic.
Kadian is used to treat moderate to severe pain.
Extended-release Kadian capsules are used when around-the-clock pain relief is needed. This form of morphine is not for use on an as-needed basis for pain.
Kadian may also be used for purposes not listed in this medication guide.
You should not take Kadian if you have severe asthma or breathing problems, a blockage in your stomach or intestines, or a bowel obstruction called paralytic ileus.
Morphine can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never take Kadian in larger amounts, or for longer than prescribed. Do not crush or break an extended-release tablet. Swallow it whole to avoid exposure to a potentially fatal dose.
Morphine may be habit-forming, even at regular doses. Take Kadian exactly as prescribed by your doctor. Never share the medicine with another person. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Tell your doctor if you are pregnant. Kadian may cause life-threatening withdrawal symptoms in a newborn if the mother has taken this medicine during pregnancy.
Do not drink alcohol. Dangerous side effects or death could occur.
Before using Kadian
You should not take Kadian if you have ever had an allergic reaction to morphine or other narcotic medicines, or if you have:
severe asthma or breathing problems;
a blockage in your stomach or intestines; or
a bowel obstruction called paralytic ileus.
Do not use Kadian if you have used a MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
You may not be able to take Kadian if you are NOT already being treated with a similar opioid (narcotic) pain medicine and are tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.
Kadian may be habit-forming. Never share morphine with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it. Selling or giving away Kadian to any other person is against the law.
Some medicines can interact with morphine and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. Ask your doctor before making any changes in how or when you take your medications.
To make sure Kadian is safe for you, tell your doctor if you have:
any type of breathing problem or lung disease;
a history of head injury, brain tumor, or seizures;
a history of drug abuse, alcohol addiction, or mental illness;
liver or kidney disease;
problems with your gallbladder, pancreas, or thyroid; or
if you use a sedative like Valium (diazepam, alprazolam, lorazepam, Ativan, Klonopin, Restoril, Tranxene, Versed, Xanax, and others).
It is not known whether Kadian will harm an unborn baby. If you use morphine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Morphine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How should I use Kadian?
Kadian may be habit-forming, even at regular doses. Take Kadian exactly as prescribed by your doctor. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH.
Follow all directions on your prescription label. Morphine can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never take Kadian in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Always check your bottle to make sure you have received the correct pills (same brand and type) of medicine prescribed by your doctor. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.
Stop taking all other around-the-clock narcotic pain medications when you start taking Kadian.
Do not crush or chew the pellets found inside a Kadian capsule.
To make swallowing easier, you may open the extended-release Kadian capsule and sprinkle the pellets into a spoonful of applesauce. Swallow all of the mixture right away without chewing. Do not save for later use.
Take the medicine at the same time each day.
Do not stop using Kadian suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using morphine.
Never crush the pelletes in a Kadian capsule to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death.
Store Kadian at room temperature, away from heat, moisture, and light.
Keep track of the amount of medicine used from each new bottle. Morphine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover Kadian capsules. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program flush any unused capsules down the toilet. Disposal of medicines by flushing is recommended to reduce the danger of accidental overdose causing death. This advice applies to a very small number of medicines only. The FDA, working with the manufacturer, has determined this method to be the most appropriate route of disposal and presents the least risk to human safety.

What happens if I miss a dose?
Kadian is taken once or twice per day. Since morphine is used for pain, you are not likely to miss a dose. If you do miss a dose, take the medicine as soon as you remember. Then take your next dose as follows:
If you take Kadian 2 times per day: Take your next dose 12 hours after taking the missed dose.
If you take Kadian 1 time per day: Take your next dose 24 hours after taking the missed dose.
Do not take extra medicine to make up a missed dose. Do not take more than your prescribed dose in a 24-hour period.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A morphine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, and fainting.
What should I avoid?
Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with morphine.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how Kadian will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Kadian side effects
Get emergency medical help if you have signs of an allergic reaction to Kadian: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Like other narcotic medicines, morphine can slow your breathing. Death may occur if breathing becomes too weak.
Call your doctor at once if you have:
slow heart rate, sighing, weak or shallow breathing;
chest pain, fast or pounding heartbeats;
extreme drowsiness, feeling like you might pass out;
infertility, missed menstrual periods;
impotence, sexual problems, loss of interest in sex; or
low cortisol levels - nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Morphine is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.
Common Kadian side effects may include:
constipation, stomach pain, nausea, vomiting;
headache, tired feeling;
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect Kadian?
Narcotic (opioid) medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:
other narcotic medications - opioid pain medicine or prescription cough medicine;
drugs that make you sleepy or slow your breathing - a sleeping pill, muscle relaxer, sedative, tranquilizer, or antipsychotic medicine; or
drugs that affect serotonin levels in your body - medicine for depression, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting.
