What is Morphine and why is it prescribed?
Morphine is used to relieve moderate to severe pain. Morphine may be taken once or twice a day. Morphine is intended for people who need a pain­killer for more than just a few days. Like other narcotics, Morphine is potentially addictive. If you take Morphine for some time and then stop abruptly, you could experience withdrawal symptoms.

How should you take Morphine?
Follow your doctors directions for taking Morphine. Swallow the Morphine tablets whole. If you crush or chew the tablets, a dangerously large amount of morphine could enter your bloodstream all at once. Morphine 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 Morphine. 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 two doses at once. Store Morphine at room temperature in a tightly closed container, away from light and moisture.

Are there any Morphine side effects?
Morphine side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. As with other narcotics, the most hazardous potential side effect of Morphine is respiratory depression. 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 Morphine side effects may include anxiety, constipation, depressed or irritable mood, dizziness, drowsiness, exaggerated sense of well-being, light-headedness, nausea, sedation, sweating, and vomiting. You may be able to lessen some of these side effects by lying down. Less common Morphine 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, and weakness. Other side effects reported during trials of Morphine 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, 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, and voice changes. If you stop taking Morphine 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, and 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.

What are the possible food and drug interactions when taking Morphine?
If Morphine is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. It is especially important to check with your doctor before combining Morphine with 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), or Water pills (such as Diuril and Lasix).

Are there any special warnings about Morphine?
Morphine 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 Morphine with extreme caution if you have any of the following conditions: Alcoholism, Coma, Curvature of the spine, Delirium tremens, Drug-related psychosis, Enlarged prostate or constricted urinary canal, Kidney disorder, Liver disorder, Low adrenalin levels, Low thyroid levels, Lung disorder, or Swallowing difficulty. If taken by an epileptic person, Morphine could increase the likelihood of a seizure. Since Morphine 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. Morphine can lower blood pressure; you may feel dizzy or light-headed, especially when you first stand up.
