Medication Guide
KADIAN® (key-dee-un) 
(morphine sulfate)
Extended-Release Capsules, CII
  • A strong prescription pain medicine that contains an opioid (narcotic) that is used to manage pain severe enough to require daily around-the-clock, long-term treatment with an opioid, 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.
  • A long-acting (extended-release) opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed you are at risk for opioid addiction, abuse, and misuse that can lead to death.
  • Not for use to treat pain that is not around-the-clock.
Important information about KADIAN:
  • Get emergency help or call 911 right away if you take too much KADIAN (overdose). When you first start taking KADIAN, when your dose is changed, or if you take too much (overdose), serious or life- threatening breathing problems that can lead to death may occur.  Talk to your healthcare provider about naloxone, a medicine for the emergency treatment of an opioid overdose.
  • Taking KADIAN with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.
  • Never give anyone else your KADIAN. They could die from taking it. Selling or giving away KADIAN is against the law.
  • Store KADIAN securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.
Do not take KADIAN if you have:
  • severe asthma, trouble breathing, or other lung problems.
  • a bowel blockage or have narrowing of the stomach or intestines.
Before taking KADIAN, tell your healthcare provider if you have a history of:
  • head injury, seizures • liver, kidney, thyroid problems
  • problems urinating • pancreas or gallbladder problems
  • abuse of street or prescription drugs, alcohol addiction, opioid overdose, or mental health problems.
Tell your healthcare provider if you are:
  • pregnant or planning to become pregnant. Prolonged use of KADIAN during pregnancy can cause withdrawal symptoms in your newborn baby that could be life-threatening if not recognized and treated.
  • breastfeeding.  Not recommended during treatment with KADIAN. It may harm your baby.
  • living in a household where there are small children or someone who has abused street or prescription drugs.
  • taking prescription or over-the-counter medicines, vitamins, or herbal supplements.  Taking KADIAN with certain other medicines can cause serious side effects.

  • Do not change your dose. Take KADIAN exactly as prescribed by your healthcare provider. Use the lowest dose possible for the shortest time needed.
  • Take your prescribed dose every 12 or 24 hours at the same time every day. Do not take more than your prescribed dose in 24 hours. If you miss a dose, take your next dose at your usual time.
  • Swallow KADIAN whole. Do not cut, break, chew, crush, dissolve, snort, or inject KADIAN because this may cause you to overdose and die.
  • You should not receive KADIAN through a nasogastric tube.
  • If you cannot swallow KADIAN capsules, see the detailed Instructions for Use.   
  • Call your healthcare provider if the dose you are taking does not control your pain.      
  • Do not stop taking KADIAN without talking to your healthcare provider.
