Information on Tablets A-Z
MS ContinPronounced: em-ess KON-tin
Generic name: Morphine sulfate
Other brand name: Kadian
Why is this drug prescribed: MS Contin, a controlled-release tablet containing morphine, is used to relieve moderate to severe pain. While regular morphine is usually given every 4 hours, MS Contin is typically taken every 12 hours--only twice a day. The Kadian brand may be taken once or twice a day. The drugs are intended for people who need a morphine painkiller for more than just a few days.
Most important fact about this drug: Like other narcotics, MS Contin is potentially addictive. If you take MS Contin for some time and then stop abruptly, you could experience withdrawal symptoms. For this reason, do not make dosage changes on your own; always consult your doctor.
How should you take this medication: Take MS Contin exactly as prescribed by your doctor--typically one tablet every 12 hours. Swallow the tablets whole. If you crush or chew the tablets, a dangerously large amount of morphine could enter your bloodstream all at once. Kadian capsules and the pellets they contain should not be dissolved, or mixed with food, either. Do not increase the dose or take the drug more frequently than prescribed. It will take a little time for the drug to begin working. Do not drink alcoholic beverages while using MS Contin. --If you miss a dose... Take the forgotten dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once. --Storage instructions... Store at room temperature in a tightly closed container, away from light and moisture.
What side effects may occur: Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor immediately. Only your doctor can determine whether it is safe for you to continue taking MS Contin. As with other narcotics, the most hazardous potential side effect of MS Contin is respiratory depression (dangerously slow breathing). If you are older or in a weakened condition, you are particularly vulnerable to respiratory depression; you may be at special risk at any age if you have a lung or breathing problem. More common side effects may include: Anxiety, constipation, depressed or irritable mood, dizziness, drowsiness, exaggerated sense of well-being, light-headedness, nausea, sedation, sweating, vomiting You may be able to lessen some of these side effects by lying down. Less common side effects may include: Agitation, allergic reaction, appetite loss, apprehension, blurred vision, chills, constipation, cramps, depression, diarrhea, difficult urination disorientation, double vision, dreams, dry mouth, facial flushing, fainting, faintness, floating feeling, hallucinations, headache, high blood pressure, hives, inability to urinate insomnia, involuntary movement of the eyeball, itching, low blood pressure, mood changes, nervousness "pinpoint" pupils, rapid heartbeat, rash, rigid muscles, seizure, sexual drive or performance problems, slow heartbeat, sweating, swelling due to fluid retention, taste alterations, throbbing heartbeat, tingling or pins and needles, tremor, uncoordinated muscle movements, vision disturbances, weakness Other side effects reported during trials of Kadian include: Abdominal pain, abnormal thinking, accidental injury, anemia, apathy, asthma, back pain, bedsores, blood disorders, bone pain, breast development in males, chest pain, confusion, conjunctivitis (pinkeye), difficulty swallowing, feeling of illness, fever, fluid in the lungs, flushing, flu symptoms, heartburn, hiccups, inability to concentrate, indigestion, irregular heartbeat, joint pain, lack of menstrual period, lack of sensation, memory loss, nasal inflammation, pain, pallor, sluggishness, slurred speech, vertigo, voice changes If you stop taking MS Contin after a long period of use, you will probably experience some degree of narcotic withdrawal syndrome. During the first 24 hours, you may have: dilated pupils, goose bumps, restlessness, restless sleep, runny nose, sweating, tearing, or yawning. Over the next 72 hours, the following may be added: Abdominal and leg pains, abdominal and muscle cramps, anxiety, diarrhea, hot and cold flashes, inability to fall or stay asleep, increase in body temperature, blood pressure, and breathing and heart rate, kicking movements, loss of appetite, nasal discharge, nausea, severe backache, sneezing, twitching and spasm of muscles, vomiting, weakness Even without treatment, your withdrawal symptoms will probably disappear within a week or two. However, you could experience a second phase of withdrawal, involving aching muscles, irritability, and insomnia, which might last for 2 to 6 months.
Why should this drug not be prescribed: Do not take MS Contin if you have ever had an allergic reaction to morphine or are sensitive to it, or if you have bronchial asthma. If your breathing is abnormally slow, you should not take MS Contin unless there is resuscitation equipment nearby. MS Contin should not be prescribed if you are suffering an intestinal blockage.
Special warnings about this medication: MS Contin should not be used by anyone who might have a brain injury, or the beginnings of an abdominal problem requiring surgery; the drug could mask the symptoms, making correct diagnosis difficult or impossible. For people facing biliary tract surgery, there is a chance that the drug could make their condition worse. Your doctor will also prescribe MS Contin with extreme caution if you have any of the following conditions: Alcoholism Coma Curvature of the spine Delirium tremens (severe alcohol withdrawal) Drug-related psychosis Enlarged prostate or constricted urinary canal Kidney disorder Liver disorder Low adrenalin levels Low thyroid levels Lung disorder Swallowing difficulty If taken by an epileptic person, MS Contin could increase the likelihood of a seizure. Since MS Contin can impair judgment and coordination, do not drive, climb, or operate hazardous equipment while taking this drug. If you become overly calm or lethargic, call your doctor. MS Contin can lower blood pressure; you may feel dizzy or light-headed, especially when you first stand up.
Possible food and drug interactions when taking this medication: If MS Contin is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining MS Contin with the following: Alcohol Certain analgesics such as Talwin, Nubain, Stadol, and Buprenex Drugs that control vomiting, such as Compazine and Tigan Drugs classified as MAO inhibitors, such as the antidepressants Nardil and Parnate Major tranquilizers such as Thorazine and Haldol Muscle relaxants such as Flexeril and Valium Sedatives such as Dalmane and Halcion Tranquilizers such as Librium and Xanax Water pills such as Diuril and Lasix
Special information if you are pregnant or breastfeeding: If you are pregnant or plan to become pregnant, inform your doctor immediately. Although there is no evidence so far that a pregnant woman's short-term use of MS Contin can harm her unborn baby, this drug should be taken during pregnancy only if the benefit to the mother outweighs a possible risk to the child. MS Contin is not recommended for use as a painkiller during childbirth. If a woman takes this drug shortly before giving birth, her baby may have trouble breathing. Babies born to mothers who use morphine chronically may suffer from drug withdrawal symptoms. Since some of the morphine from MS Contin appears in breast milk, do not take this medication while breastfeeding. If you do nurse while using MS Contin, your baby could experience withdrawal symptoms once you stop taking this medication.
Recommended dosage: Because MS Contin and Kadian are so potent, the doctor will set the dosage schedule and amount to meet your individual needs.
Overdosage: Any medication taken in excess can have serious consequences. An overdose of MS Contin can be fatal. If you suspect an overdose, seek medical attention immediately. Symptoms of MS Contin overdose may include: Cold, clammy skin, flaccid muscles, fluid in the lungs, lowered blood pressure, "pinpoint" or dilated pupils, sleepiness leading to stupor and coma, slowed breathing, slow pulse rate
