How does this medication work? What will it do for me?
Morphine belongs to the class of medications called narcotic analgesics (pain relievers). These pain relievers are also known as opioid analgesics. This medication relieves severe pain when less potent pain relievers are not effective. Opioids decrease pain by working on the brain to increase pain tolerance. Morphine immediate release works quickly. It will usually relieve pain within about 30 minutes.

How should I use this medication?
Doses of morphine vary widely and depend on an individual's circumstances.
After a certain dose of morphine has been taken for a period of time, the body often gets used to it and a higher dose of morphine is needed to relieve the pain. Generally, your doctor will try to find the dose of morphine that will give you acceptable pain relief without an unacceptable level of side effects. This helps to reduce the side effects of the medication and allows for the dose to be adjusted upwards if needed. Always check with your doctor if you feel your medication isn't working well anymore.
Over time, this medication may produce tolerance and physical dependence as your body becomes used to the medication. Tolerance occurs when a dose that used to provide acceptable pain relief is no longer effective, and higher doses are required to achieve the same level of pain relief. Physical dependence is a state where the body will go into withdrawal if the medication is stopped suddenly. If you have been taking morphine on a regular basis for a long period of time, talk to your doctor before stopping the medication, as withdrawal effects can occur.
Tolerance and physical dependence are not the same as addiction. Addiction is defined as a psychological need to use the medication for reasons other than pain relief. Although people may become addicted to this medication, it is most common for people who have had addictions to other substances in the past.
The liquid form of morphine may be mixed with a glass of fruit juice just before taking it to improve the taste.
If you are using a suppository, first remove the foil wrapper and moisten the suppository with cold water. Lie down on your side and use your finger to push the suppository well up into the rectum. If you find the suppository is too soft to insert, chill it in the refrigerator for 30 minutes or run cold water over it before removing the foil wrapper.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abdominal (stomach) conditions: Morphine and other narcotic medications may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have abdominal or stomach problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Asthma and other respiratory conditions: Morphine may cause increased breathing difficulty for people having an acute asthma attack or those with chronic obstructive pulmonary disease (chronic bronchitis, emphysema) or other conditions that affect breathing. If you have asthma or other breathing disorders, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dependence and withdrawal: Drug addiction is usually not a problem for people who require this medication for pain relief. Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with narcotic analgesics such as morphine. Withdrawal symptoms may be experienced if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, headache, muscle cramps, extreme anxiety, tension, restlessness, sweating, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms when this medication is no longer required for pain control.
Drowsiness/reduced alertness: Morphine may impair the mental or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. You should avoid such activities until you are certain this medication does not have this effect on you.
Head injury: Morphine can cause increased pressure inside the head. If you have an acute head injury or other conditions that increase your intracranial pressure (pressure inside the head), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Other medical conditions: Morphine may cause increased symptoms or reduce the symptoms of worsening illness for people with the following conditions:
If you have any of these conditions, you should discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Seizures: Morphine may worsen pre-existing seizure disorders. If tolerance to the medication develops and the dosage is increased substantially above recommended levels, seizures may occur in people without a history of seizure disorders. If you have a seizure disorder, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking morphine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Seniors: Seniors may be more sensitive to the side effects of this medication and may require lower doses.
