What is Kadian?
Kadian (morphine) is an opioid medication. An opioid is sometimes called a narcotic.
Kadian extended-release capsules are used to treat moderate to severe pain.
Kadian extended-release capsules are used for around-the-clock treatment of pain when other pain treatments, such as non-opioid pain medicines or immediate-release opioid medicines, do not treat your pain well enough or you cannot tolerate them.
Kadian is not for use on an as-needed basis for pain.
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, and may be habit-forming MISUSE OF KADIAN CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, , especially in a child or other person using the medicine without a prescription. Keep the medication in a place where others cannot get to it.
Taking Kadian during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use Kadian with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
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; or
a blockage in your stomach or intestines.
Do not use Kadian if you have used an 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.
To make sure Kadian is safe for you, tell your doctor if you have ever had:
breathing problems, sleep apnea;
a drug or alcohol addiction, or mental illness;
liver or kidney disease; or
problems with your gallbladder, pancreas, or thyroid.
If you use opioid medicine 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 opioids may need medical treatment for several weeks.
Do not breast-feed while taking morphine. Morphine can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.
How should I use Kadian?
Take Kadian exactly as prescribed by your doctor. Follow the directions on your prescription label and read all medication guides. Never use morphine in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.
Never share opioid medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it. Selling or giving away opioid medicine is against the law.
Stop taking all other around-the-clock narcotic pain medications when you start taking Kadian.
Swallow the capsule whole to avoid exposure to a potentially fatal overdose. Crushing, chewing, or dissolving the pellets will result in uncontrolled delivery of morphine and can lead to overdose or death.
To make swallowing easier, you may open the extended-release capsule and sprinkle the medicine into a spoonful of applesauce. Swallow right away without chewing. Rinse the mouth to ensure all pellets have been swallowed. Do not save the mixture for later use.
Do not stop using Kadian suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
Never crush or break 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 with the misuse of morphine and similar prescription drugs.
Store at room temperature, away from heat, moisture, and light. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.

Appropriate dose should be taken 1 to 2 times daily.
What happens if I miss a dose?

Kadian side effects
